Overview

What this SWMS covers

Electrical new installation work represents the foundation of building electrical infrastructure, involving the systematic installation of electrical systems from initial service connection through to final commissioning in new construction projects. This work requires licensed electricians to coordinate with architects, engineers, builders, and other trades to deliver electrical installations meeting Australian Wiring Rules, client specifications, energy efficiency requirements, and occupational health and safety regulations. The scope and complexity of new electrical installations varies dramatically from simple domestic installations in residential houses through to complex commercial office buildings, industrial facilities, and infrastructure projects. New electrical installation work typically progresses through distinct phases aligned with building construction sequencing. The first phase involves establishing temporary builder's supply providing power for construction tools, site lighting, and temporary facilities during construction. This temporary installation must be designed for robustness in harsh construction environments, positioned to avoid interference with permanent works, and maintained in safe condition throughout construction. The second phase, commonly called 'rough-in' or 'first fix', occurs after structural framing is complete but before wall and ceiling linings are installed. Electricians install conduits, cable trays, and containment systems, run cables through wall and ceiling cavities, install switchboards and distribution boards, install wall boxes for power outlets and switches, and coordinate cable routes with plumbing, HVAC, and other services. The third phase, known as 'second fix' or 'trim out', occurs after wall and ceiling linings are installed and typically after painting is complete. Electricians install power outlets and switches into previously installed wall boxes, connect light fixtures and ceiling fans, install door bells and communication systems, connect hardwired appliances such as air conditioning units and hot water systems, and install external fixtures including security lighting and power outlets. The final phase involves testing and commissioning where electricians conduct insulation resistance testing, earth continuity testing, RCD operation testing, polarity checks, and circuit verification before energising systems and conducting functional testing of all electrical equipment. Electrical new installation requires detailed planning and coordination to sequence work appropriately with other construction activities. Electricians must install underground conduits before concrete slabs are poured, coordinate ceiling cavity work with plumbers and HVAC installers, ensure switchboard locations are accessible and compliant, provide adequate electrical capacity for current and future loads, comply with disability access requirements for switch and outlet heights, integrate smart building systems and communications infrastructure, meet minimum energy efficiency requirements, and coordinate with supply authorities for service connection timing. This coordination complexity means electrical contractors must maintain regular communication with project managers, attend site meetings, monitor construction progress, and adapt installation sequences as building construction progresses. The scale of electrical new installation work varies significantly across project types. Residential electrical installations typically involve 10-20 lighting circuits, 5-10 power circuits, switchboard with 20-40 circuit positions, multiple power outlets per room meeting Australian Standards minimums, external lighting and power for outdoor areas, hardwired appliance connections, and increasingly solar PV systems and electric vehicle charging. Commercial electrical installations add complexity through three-phase power distribution, emergency and exit lighting systems, fire detection and alarm systems, communications and data cabling infrastructure, security and access control systems, and coordination with building management systems. Industrial electrical installations further increase complexity with high-voltage distribution, motor control circuits, specialised equipment power supplies, hazardous area wiring requirements, and complex earthing and bonding systems. Licensed electricians must possess appropriate competency levels for the installation complexity they undertake.

Why this SWMS matters

Electrical new installation work forms the permanent electrical infrastructure of buildings that must operate safely and reliably for decades. Inadequate electrical installation creates serious immediate and long-term consequences including electrocution of building occupants from incorrectly wired electrical circuits, electrical fires from overloaded circuits or poor connections causing tens of millions of dollars in property damage annually in Australia, equipment damage from incorrect voltage or phase connections, inability to obtain building occupancy certificates when installations fail compliance inspections, and costly remediation work to correct installation defects discovered during or after construction. The quality and safety of electrical installations directly affects building safety, functionality, energy efficiency, and occupant satisfaction throughout the building's operational life. Under the Work Health and Safety Act 2011, electrical installation is classified as high-risk construction work requiring documented Safe Work Method Statements before work commences. The WHS Regulations Section 291 specifically addresses electrical work, mandating that electrical work is performed by licensed electricians holding appropriate qualifications, electrical installations are designed and installed to prevent risks to health and safety, adequate testing and inspection is conducted to verify installation safety and compliance, and proper documentation is maintained throughout installation work. These requirements reflect the serious consequences of electrical installation failures and the specialised knowledge required to install electrical systems safely. Electrical licensing requirements across Australian states and territories mandate minimum qualifications, training, and supervision for electrical installation work. Unrestricted electrical licences allow installation of any electrical work including high-voltage systems and complex commercial installations. Restricted electrical licences limit work scope to domestic installations, specific voltage levels, or defined installation types. Apprentice electricians must work under direct supervision of licensed electricians with appropriate supervision ratios maintained at all times. These licensing requirements exist because electrical installation requires deep understanding of electrical theory, Australian Wiring Rules, electrical hazards, safe work practices, and practical installation techniques that can only be developed through structured training and supervised experience. Unlicensed electrical work is not only illegal but creates serious safety risks and invalidates insurance coverage, building approvals, and manufacturer warranties for electrical equipment. Compliance with AS/NZS 3000 Wiring Rules is mandatory for all electrical installations in Australia. The Wiring Rules specify detailed technical requirements including minimum conductor sizes for different circuit types and load capacities, required disconnection times for protective devices, earthing and bonding requirements, installation methods for different wiring systems, clearances from other services and structural elements, IP ratings for equipment in different environmental conditions, and special requirements for hazardous areas, hospitals, and agricultural installations. Electrical installations that fail to comply with Wiring Rules requirements do not meet legal obligations under electrical safety regulations, will fail compliance inspections by electrical safety regulators, cannot be energised by electricity supply authorities, and create liability for electrical contractors if defects cause incidents. Recent amendments to AS/NZS 3000 have introduced requirements for arc fault detection devices in certain applications, surge protection devices, and minimum energy efficiency standards reflecting evolving safety and sustainability priorities. Electrical new installation involves significant coordination with other construction trades creating interface hazards if not properly managed. Electricians work in ceiling cavities alongside plumbers and HVAC installers where physical conflict over space, accidental damage to services, and falling object hazards are common. Electrical conduits installed in concrete slabs can be damaged by concrete pumping operations or reinforcement placement if not adequately protected. Switchboards installed in wet areas require waterproofing coordination with builders to prevent moisture ingress. Underground electrical services require careful coordination with earthworks contractors, landscaping teams, and civil works to prevent damage during subsequent excavation. These coordination challenges require proactive communication, well-defined work sequencing, adequate trade separation when necessary, and comprehensive hazard identification addressing multi-trade environments. Construction sites where coordination breaks down experience elevated incident rates, costly rework, schedule delays, and compromise safety of all trades. From a quality assurance perspective, electrical new installation must satisfy multiple inspection and approval stages before buildings can be occupied and electrical systems energised. Inspections typically include rough-in inspections before wall and ceiling linings conceal wiring, verifying cable types and sizes comply with specifications, confirming switchboards are properly installed and labelled, and checking adequate protection and separation from other services. Final inspections occur after completion of installation, requiring demonstration that all circuits are complete and functional, adequate testing has been conducted and documented, labelling and documentation is complete, and the installation complies with Wiring Rules and specifications. Electrical supply authorities conduct separate connection inspections verifying service installation is safe for connection to the distribution network. Building certifiers review electrical compliance certificates as prerequisite for issuing occupancy certificates. This multi-stage inspection regime reflects the critical importance of electrical installation quality and safety. Comprehensive SWMS documentation demonstrates systematic approach to safety and quality, facilitating smoother inspection processes and demonstrating professional standards.

Hazard identification

Surface the critical risks tied to this work scope and communicate them to every worker.

Risk register

Electrocution from Contact with Existing Energised Electrical Systems

High

Despite new installation work being conducted in buildings without permanent electrical supply, electricians frequently encounter electrocution risks from temporary construction power supplies, neighbouring properties' electrical systems, and inadvertent energisation during installation work. Temporary builder's supply circuits may be damaged by construction activities, creating exposed energised conductors. Underground electrical cables from neighbouring properties may be encountered during trenching for new service connections. Overhead power lines near construction sites create electrocution risks when installing electrical services, using elevated work platforms, or handling long lengths of conduit or cable. During commissioning phases, electrical systems become energised while installation work continues, creating live work situations if not properly coordinated. The consequences include electrocution causing cardiac arrest and death, severe electrical burns requiring extended hospitalisation and permanent scarring, and falls from heights when electric shock causes loss of balance. Electricians may become complacent during new installation work assuming no electrical hazards exist, failing to implement isolation and testing procedures when working near temporary supplies or during energisation phases. Construction environments with multiple trades working simultaneously increase the risk that temporary electrical systems are damaged or modified by other workers, creating unexpected hazards for electricians returning to work areas.

Falls from Heights During Ceiling and Elevated Installation Work

High

Electrical new installation requires extensive work at heights including installing ceiling light fixtures, running cables through ceiling cavities, installing switchboards at elevated positions, mounting cable trays and conduits on walls and ceilings, and connecting services at roof level. Falls from heights represent a leading cause of construction fatalities and serious injuries. This hazard is elevated in new construction where access equipment must be positioned on rough concrete slabs with debris, where structural elements are incomplete affecting fall protection anchor point availability, where ceiling access requires working from ladders or platforms in confined roof spaces, and where electricians must handle heavy equipment or long lengths of conduit while maintaining balance on elevated platforms. The physical demands of electrical installation work frequently require both hands, preventing maintenance of continuous handhold on ladders. Cable pulling operations create reaction forces that can destabilise electricians working on ladders or platforms. Ceiling cavity work involves walking on ceiling joists or battens where a misstep results in falling through ceiling linings to floor level below. The cumulative fatigue from repetitive climbing and elevated work throughout the day increases fall risk as physical and mental fatigue affects balance and judgement. Young apprentice electricians without extensive experience working at heights face elevated risk due to lack of familiarity with height hazards and overconfidence in their abilities.

Manual Handling Injuries from Heavy Electrical Equipment and Materials

Medium

Electrical new installation involves extensive manual handling of heavy equipment and materials including switchboards weighing up to 200kg requiring multiple persons or mechanical aids, cable drums containing hundreds of metres of cable weighing several hundred kilograms, distribution boards and sub-boards ranging from 20-50kg, conduit in 3-6 metre lengths creating awkward lifting and carrying, bags of fittings and accessories carried repeatedly throughout the day, and ladders and elevated work platforms moved frequently between work locations. Repetitive manual handling throughout installation creates cumulative strain on backs, shoulders, and knees even when individual lifts are manageable. Awkward lifting positions are common when installing switchboards at height, pulling cables through ceiling cavities with restricted postures, and positioning equipment in confined spaces. Team lifting operations require coordination between workers to prevent uneven loading. Manual handling in new construction occurs on rough surfaces with debris creating trip hazards, on uneven or sloped ground affecting balance, and in tight spaces where proper lifting techniques cannot be employed. The consequences of inadequate manual handling practices include acute back injuries requiring immediate medical attention and time off work, chronic musculoskeletal disorders developing over time from cumulative strain, shoulder injuries from overhead work and repetitive reaching, and knee injuries from frequent squatting and kneeling during installation activities. Manual handling injuries are the most common cause of workers compensation claims in electrical contracting, creating substantial costs through lost productivity, injured worker rehabilitation, and workers compensation premiums.

Electrical Arc Flash During Energisation and Commissioning

High

Arc flash incidents occur during electrical installation commissioning phases when newly installed electrical systems are energised for testing, during energised testing of circuits with unintentional short circuits or equipment faults, when inadvertent contact occurs between conductors during termination work in switchboards, or when energised equipment fails during testing due to installation defects. The intense heat of electrical arcs reaching temperatures above 10,000 degrees Celsius causes devastating burns, vaporises metal components creating molten projectiles, generates explosive pressure waves causing blast injuries, and ignites flammable materials including clothing and construction debris. Commissioning phases of electrical installation create elevated arc flash risk because new installations may contain undetected wiring errors, equipment may have manufacturing defects discovered only when energised, protective device settings may not be coordinated correctly, and fault current levels are uncertain until actual supply is connected. Electricians conducting commissioning may focus on functional testing without adequately considering arc flash hazards. The pressure to energise systems quickly to meet project deadlines can lead to shortcuts in testing procedures or inadequate personal protective equipment use. Arc flash incidents during commissioning have caused fatalities and life-changing burn injuries that could have been prevented through proper testing sequences and appropriate arc-rated PPE.

Struck by Falling Objects and Materials from Height

Medium

Electrical installation in new construction involves work at multiple levels simultaneously, creating struck-by hazards when tools, materials, or equipment fall from elevated work areas. Electricians working below ceiling level face risks from tools dropped by workers in ceiling cavities, lengths of conduit falling during installation at height, cable drums rolling off elevated platforms, fittings and accessories dropped during overhead installation work, and ladders or platforms collapsing due to overloading or instability. The dynamic nature of construction sites means work areas below electricians may be occupied by other trades who are unaware of overhead work. Tools and materials stored on elevated work platforms or ladder platforms can be knocked off by inadvertent contact. Cable pulling operations involving multiple workers can cause tools and equipment to fall when cables snag on stored items. Construction sites with inadequate housekeeping have elevated falling object risks as debris accumulates on platforms, in ceiling cavities, and on elevated surfaces creating opportunities for materials to fall. The consequences of struck-by incidents depend on falling object mass, fall height, and impact location. Hand tools falling from ceiling height can cause serious head injuries even when wearing safety helmets. Heavier items such as switchboards or cable drums falling from height cause fatal crush injuries. Eye injuries from small falling particles are common when working below other trades.

Confined Space Entry During Underground Cable Installation

High

Electrical new installation frequently requires entry into confined spaces including underground cable pits, service tunnels, ceiling cavities with limited access, subfloor areas, and electrical equipment rooms with restricted entry. These confined space entries create compounded hazards where limited ventilation causes oxygen depletion or accumulation of hazardous gases, restricted entry and exit points prevent rapid emergency egress, inadequate lighting obscures hazards and creates trip and fall risks, and limited working space creates awkward postures and manual handling difficulties. Underground cable pits may accumulate water requiring dewatering or work in wet conditions, may contain hazardous atmospheres from sewer gases or decomposing materials, and may have inadequate structural integrity causing collapse risks. Working in ceiling cavities combines confined space risks with heat stress in summer months when ceiling temperatures exceed 60 degrees Celsius, asbestos exposure if older buildings contain asbestos insulation, and electrical hazards from existing services. The restricted emergency egress from confined spaces means any incident including electric shock, medical emergency, or atmospheric contamination becomes more serious due to delayed rescue. Confined space incidents frequently result in multiple fatalities when would-be rescuers enter spaces to assist collapsed workers without proper equipment or atmospheric testing, succumbing to the same atmospheric hazards.

Control measures

Deploy layered controls aligned to the hierarchy of hazard management.

Implementation guide

Field ready
1

Review Electrical Plans and Conduct Pre-Installation Site Assessment

Begin electrical new installation by comprehensively reviewing electrical design drawings, specifications, and conducting site assessment to understand installation requirements and site conditions. Obtain complete set of electrical drawings including site plans, floor plans, switchboard layouts, lighting layouts, power layouts, and single-line diagrams showing electrical distribution architecture. Review electrical specifications identifying cable types, switchboard equipment, circuit protection devices, and special requirements such as emergency lighting, exit lighting, or communications systems. Study architectural and structural drawings identifying building layout, structural elements affecting electrical installation, ceiling cavity configurations, and coordination requirements with other services. Conduct physical site inspection walking entire building to verify actual conditions match drawings, identifying any site constraints affecting installation such as limited ceiling cavity height, restricted switchboard locations, or difficult cable routes. Identify interface locations with other trades including plumbing, HVAC, and fire services where coordination will be required to prevent service conflicts. Assess temporary electrical supply requirements determining circuit capacity needed for power tools, temporary lighting, and construction equipment throughout installation period. Plan material storage locations ensuring electrical materials are stored in weather-protected areas secure from theft and damage. Identify access requirements for electrical installation including scaffold, elevated work platforms, and ceiling access equipment. Prepare electrical installation work plan documenting installation sequence, resource requirements, coordination activities, and key milestones aligned with overall construction schedule.

Safety considerations

Inadequate planning and site assessment leads to installation problems, rework, and safety issues when electricians encounter unexpected conditions. Comprehensive planning prevents coordination conflicts with other trades and ensures adequate resources are available throughout installation.

2

Install Temporary Builder's Electrical Supply

Establish temporary electrical supply system providing power for construction activities throughout building construction period. Coordinate with electrical supply authority or existing facility management if temporary supply will connect to existing electrical systems. Install temporary distribution board in weatherproof location accessible to all trades but secure from unauthorised access. Run temporary sub-main cables from supply connection point to temporary distribution board using appropriate cable types for outdoor installation and mechanical protection. Install temporary power outlets at locations throughout building providing convenient power access for all construction areas. Connect temporary lighting circuits providing adequate illumination for safe construction work and emergency egress, positioning temporary lights to avoid creating shadows in work areas. Install residual current devices on all temporary power circuits providing electrical shock protection for workers using power tools and equipment. Label all temporary circuits clearly identifying circuit capacity and restrictions on equipment that can be connected. Implement overcurrent protection appropriate for temporary cable types preventing cable overload. Establish lockout-tagout procedures for temporary electrical supply allowing electricians to isolate circuits when conducting installation work in specific areas. Conduct regular maintenance inspections of temporary electrical supply throughout construction period, replacing damaged cables, testing RCD operation, and ensuring weatherproofing remains effective. Document temporary electrical supply configuration including circuit layout, protection device ratings, and any restrictions on use. Coordinate with construction project manager regarding procedures for other trades accessing temporary electrical supply and reporting electrical issues.

Safety considerations

Temporary electrical supply is often subjected to harsh treatment in construction environments. Robust installation design, regular maintenance, and clear usage procedures prevent electrical incidents affecting all construction trades throughout project duration.

Install Underground Electrical Service and Conduits (First Fix Phase 1)

Coordinate installation of underground electrical service conduits and cables before concrete slab is poured. Mark electrical service entry point on building foundations based on supply authority requirements and electrical design drawings. Excavate trench from supply authority connection point to building entry point maintaining minimum depth requirements per AS/NZS 3000 (typically 600mm under roadways, 450mm elsewhere). Install electrical warning tape 300mm above underground cables warning future excavators of underground electrical services. Lay underground electrical conduits in trench bedding on fine sand or approved bedding material, ensuring conduits have adequate fall for drainage. Install draw wires through all underground conduits facilitating future cable installation. Protect underground conduits where they pass through concrete foundations using protective sleeves preventing concrete damage to conduits. Install underground cable if supply authority requires cable installation before service connection, using appropriate cable types for underground installation with mechanical protection. Install earthing system including main earth electrode, earth bar in switchboard position, and earth continuity conductors before slab pour. Install conduits through concrete slab for circuits requiring sub-floor installation including floor outlets, columns with power points, and service penetrations. Coordinate conduit positions with concrete reinforcement installation preventing damage during steel placement. Photograph all underground electrical services before concrete pour creating record of service locations for future reference. Mark conduit termination points protruding above slab level with visible tags identifying circuit destinations. Conduct final inspection before concrete pour verifying all underground services are correctly installed, adequately protected, and draw wires are installed in all conduits.

Safety considerations

Underground electrical service installation requires excavation near building foundations creating structural stability risks. Coordinate with structural engineers and builders to ensure excavation does not undermine foundations. Confined space entry may be required for deep trenches or service pits requiring atmospheric testing and rescue procedures.

Install Cable Trays, Conduits, and Containment Systems (First Fix Phase 2)

After building structural framing is complete but before wall and ceiling linings are installed, install electrical cable trays, conduits, and containment systems providing pathways for electrical cables. Mark cable tray and conduit routes on structural members using electrical drawings as reference, coordinating routes with plumbing, HVAC ducts, and other services to prevent conflicts. Install cable tray support brackets at spacings complying with AS/NZS 3000 and manufacturer specifications, ensuring adequate structural strength for loaded cable tray weight. Erect cable tray sections connecting them with approved joining methods and ensuring electrical continuity through cable tray earthing connections. Install flexible conduits at points where cables will drop from cable trays to distribution boards or equipment connection points. Run electrical conduits through wall and ceiling cavities for circuits that will be concealed, ensuring adequate support and mechanical protection. Install wall boxes for power outlets and switches at locations shown on electrical drawings, verifying heights comply with AS/NZS 3000 and disability access requirements. Label all conduits and wall boxes with circuit identification preventing confusion during cable installation phase. Install ceiling support wires and mounting points for light fixtures at positions shown on lighting layouts. Coordinate with ceiling installers regarding ceiling grid requirements for recessed light fixtures. Install access covers or junction boxes where future access to cable connections will be required. Ensure adequate clearances are maintained from plumbing, gas services, and HVAC ducts per AS/NZS 3000 separation requirements. Photograph cable tray and conduit installation creating record of service routes before concealment by building linings.

Safety considerations

Installation of cable trays and conduits at heights requires elevated work platforms or ladders. Use elevated work platforms where extended work at heights is required. Maintain fall protection by wearing fall arrest harnesses connected to suitable anchor points when working above 2 metres height.

5

Install Switchboards and Distribution Boards (First Fix Phase 3)

Install main switchboard and distribution boards at locations specified on electrical drawings. Verify switchboard installation location provides adequate clearance per AS/NZS 3000 requirements including minimum 600mm working space in front of switchboard, adequate headroom above switchboard, and no obstruction to switchboard door operation through full opening arc. Ensure switchboard mounting surface is structurally adequate to support switchboard weight which may exceed 200kg for large commercial switchboards. Use mechanical lifting aids including cranes, hoists, or forklifts for heavy switchboards to prevent manual handling injuries. Position switchboard to mounting surface ensuring it is plumb and level, using shims where necessary to achieve correct alignment. Secure switchboard to wall or mounting frame using appropriate fixings rated for switchboard weight and installation surface type. Install switchboard in location accessible for future maintenance and emergency disconnection but not exposed to weather, moisture, or physical damage. Connect main earthing conductor from switchboard earth bar to main earth electrode ensuring earth continuity and adequate conductor sizing. Install incoming service conduits to switchboard from supply authority connection point and outgoing conduits to distribution boards. Label switchboard location clearly with identification visible from normal access routes. Install distribution boards throughout building at locations providing convenient circuit distribution for building areas. Ensure distribution board heights comply with AS/NZS 3000 and disability access requirements where applicable. Connect distribution board earth bars to equipotential bonding system ensuring earth continuity throughout electrical installation. Install conduits connecting distribution boards to switchboard for sub-main cables. Verify all switchboards and distribution boards are suitable for environmental conditions where they are installed based on IP ratings and corrosion protection.

Safety considerations

Heavy switchboards require mechanical lifting to prevent manual handling injuries. Coordinate crane or hoist availability during switchboard installation planning. Multiple personnel may be required to guide switchboards into position during lifting operations, requiring clear communication between workers.

6

Install Cables Through Containment Systems (First Fix Phase 4)

Install electrical cables through cable trays, conduits, and wall/ceiling cavities for all electrical circuits. Begin with sub-main cables connecting switchboard to distribution boards, followed by final circuit cables from distribution boards to outlets and fixtures. Set up cable drums on drum stands or motorised drum lifts preventing manual handling of heavy drums. Install cable pulling equipment including mechanical cable pullers for long cable runs preventing manual strain during cable pulling. Pull cables through conduits using draw wires installed during conduit installation, applying appropriate pulling tension to prevent cable damage. For multiple cables in common conduits, pull cables simultaneously where practical rather than pulling individually. Support cables on cable trays using cable ties at regular intervals preventing cable sagging and maintaining neat installation. Install cables in wall and ceiling cavities ensuring adequate support per AS/NZS 3000 requirements (typically support every 300-450mm depending on cable type). Protect cables where they pass through metal structures using grommets or protective sleeves preventing insulation damage. Maintain adequate separation between power cables and communication cables per electromagnetic compatibility requirements. Label cables at both ends using cable tags or labels identifying circuit numbers corresponding to electrical drawings. Leave adequate service loops at switchboards, distribution boards, and equipment termination points facilitating future connection and maintenance. For three-phase installations, maintain consistent phase colours throughout installation (red, white, blue for Australian three-phase systems). Install underground cables through previously installed conduits, applying cable lubricant to reduce friction in long conduit runs. Install cable markers at regular intervals along cable routes allowing future circuit tracing.

Safety considerations

Cable pulling operations create significant physical strain. Use mechanical cable pullers for long cable runs and heavy cables to prevent manual handling injuries. Multiple workers should coordinate cable pulling with clear communication to prevent uneven loading. Work at heights during cable installation in ceiling cavities requires fall protection.

7

Terminate Cables at Switchboards and Distribution Boards (First Fix Phase 5)

Terminate electrical cables at switchboards and distribution boards preparing systems for testing and energisation. Strip cable outer sheaths to appropriate lengths exposing individual conductors while maintaining outer sheath protection to point of entry to switchboard. Strip individual conductor insulation using appropriate stripping tools ensuring no conductor damage or excessive bare conductor exposure. Terminate incoming supply cables to main switch or circuit breaker in switchboard, ensuring correct phase sequence and secure connection with appropriate terminal torque. Install circuit protection devices (circuit breakers or fuses) in switchboard positions corresponding to electrical drawings and circuit schedules. Terminate outgoing sub-main cables to appropriate circuit breakers ensuring correct circuit identification. Connect neutral conductors to neutral bar in switchboard maintaining separation from earth bar except at main earthing point. Connect earth conductors to earth bar ensuring secure mechanical and electrical connection. Install residual current devices (RCDs) in switchboard positions protecting circuits where required by AS/NZS 3000. Terminate final circuit cables at distribution boards connecting active conductors to circuit breakers, neutral conductors to neutral bar, and earth conductors to earth bar. Verify all cable terminations are secure by pull-testing conductors after termination. Double-check phase connections using circuit diagrams preventing phase reversal or incorrect phase distribution. Install switchboard circuit schedules identifying each circuit number, description, and protection device rating. Apply cable identification labels inside switchboards correlating cable identifications with circuit schedules. Verify adequate cable slack is maintained in switchboards allowing future circuit changes without cable extension. Install switchboard covers ensuring all live parts are protected from inadvertent contact.

Safety considerations

Cable termination work requires careful attention to prevent wiring errors that could cause electrocution or arc flash during energisation. Use systematic termination sequence following circuit schedules and verify all connections before closing switchboard covers. Until energisation occurs, wear electrical gloves as additional protection during termination work.

8

Install Outlets, Switches, and Fixtures (Second Fix Phase)

After wall and ceiling linings are installed and painting is complete, install electrical outlets, switches, light fixtures, and other electrical accessories (second fix or trim out phase). Install power outlets into previously installed wall boxes, connecting active, neutral, and earth conductors to appropriate terminals following consistent terminal position conventions. Verify outlet installation height complies with AS/NZS 3000 and disability access requirements where applicable. Install light switches into wall boxes ensuring correct switching function (single-pole, two-way, or three-way switching as required). Install switch plate covers and outlet covers ensuring flush fit with wall surfaces. Install light fixtures at ceiling positions, supporting fixture weight from ceiling structure (not from electrical connections alone). For recessed downlights, install in ceiling openings ensuring adequate clearance from insulation and combustible materials per IC rating requirements. Install ceiling fans ensuring adequate structural support is provided (ceiling fans must not be supported by electrical boxes alone). Connect hardwired appliances including air conditioning units, hot water systems, and range hoods, coordinating with appliance installers for correct connection requirements. Install external light fixtures and power outlets ensuring appropriate IP ratings for weather exposure and correct circuit protection with RCDs. Install door bells, intercoms, and communication outlets where specified. Conduct functional testing of all outlets, switches, and fixtures after installation, verifying correct operation before final inspection. Install smoke alarms and heat detectors at locations complying with Building Code of Australia requirements, interconnecting alarms on dedicated circuits. Label all circuits at outlets and switches where required for identification purposes.

Safety considerations

Second fix electrical work often requires ladder use for overhead installations. Use elevated work platforms instead of ladders where extended work at heights is required. Maintain fall protection when working above 2 metres height. Circuits should remain de-energised during second fix installation until installation is complete and tested.

9

Conduct Comprehensive Electrical Testing Before Energisation

Before energising electrical installation, conduct comprehensive electrical testing verifying installation quality and electrical safety. Begin with visual inspection of entire electrical installation checking cable support is adequate, terminations are secure, circuit identification is complete, and no obvious installation defects exist. Conduct insulation resistance testing on all circuits using insulation tester (megger) applying 500V DC test voltage for circuits rated up to 500V AC. Measure insulation resistance between active and neutral, active and earth, and neutral and earth, verifying resistance exceeds 1 megohm minimum requirement. Test earth continuity from main earth bar to all outlets, switches, and equipment requiring earthing, measuring earth loop resistance and verifying it does not exceed maximum values specified in AS/NZS 3000. Conduct polarity testing verifying active, neutral, and earth conductors are connected correctly throughout installation with no conductor reversals. Test all residual current devices by operating test button and using RCD tester at multiple test currents (half rated current, rated current, and five times rated current), verifying trip times comply with AS/NZS 3000 requirements. For three-phase installations, verify correct phase rotation and phase balance. Test all circuits for correct operation using circuit tracer or continuity tester before final energisation. Document all test results on electrical test sheets including test instrument details, circuits tested, results obtained, and electrician conducting testing. Rectify any test failures before proceeding with energisation, re-testing after remedial work is complete. Provide electrical test results to building certifier and electrical safety regulator as required for approval to energise.

Safety considerations

Comprehensive testing identifies wiring errors and installation defects before energisation when rectification is safer and prevents arc flash or electrocution incidents during commissioning. Never skip testing procedures due to schedule pressure as testing is critical safety verification.

10

Energise Electrical System and Conduct Final Commissioning

After testing is complete and satisfactory results documented, proceed with electrical system energisation and commissioning. Coordinate with electrical supply authority for permanent service connection ensuring supply authority connection inspection has been passed. Don appropriate arc-rated PPE if working on high-voltage systems or circuits with significant fault current capacity during energisation. Clear all non-essential personnel from electrical rooms and switchboard areas during initial energisation. Close main switch or circuit breaker in switchboard energising main busbars but with all outgoing circuits de-energised. Verify correct voltage is present at switchboard busbars using voltage testing device. Energise circuits progressively one at a time starting with distribution board supply circuits. At each distribution board, verify correct voltage at incoming supply terminals. Progressively energise final circuits from distribution boards, conducting functional tests of all outlets, switches, and equipment on each circuit before proceeding to next circuit. Test RCD operation on all circuits containing RCDs using RCD tester, verifying trip times remain within specification when system is energised and under load. Conduct functional testing of all light switches verifying correct switching operation. Test all power outlets using outlet tester verifying correct polarity and earth connection. Operate all connected appliances and equipment verifying correct operation and adequate supply voltage under load. Conduct load testing of electrical installation verifying circuit protection devices do not trip under normal load conditions. Document all energisation and commissioning activities including sequence followed, any issues identified, and remedial actions taken. Conduct final client walkthrough demonstrating switchboard operation, explaining circuit protection devices, and providing electrical maintenance recommendations.

Safety considerations

Initial energisation creates arc flash risk if installation defects exist. Energise circuits progressively with appropriate arc-rated PPE and clear non-essential personnel from electrical areas. Have fire extinguishers readily available during energisation in case electrical faults cause fires. Be prepared to de-energise immediately if any abnormal conditions are observed.

Frequently asked questions

What electrical licence do I need for new installation work in Australia?

Electrical new installation work requires appropriate electrical licences issued by state or territory electrical safety regulators. For residential electrical installation work, an electrician's licence (restricted or unrestricted) allows installation of electrical systems in domestic dwellings. For commercial and industrial electrical installations, an unrestricted electrical licence is typically required due to higher voltages, three-phase systems, and greater complexity. Apprentice electricians can conduct electrical installation work under supervision of licensed electricians, with supervision requirements specifying maximum ratios of apprentices to licensed supervisors and requirement for licensed electrician to be present on site. Electrical contractor licences are also required if operating an electrical contracting business, separate from individual electrician licences. Licensing requirements vary between states and territories, with some jurisdictions having additional licence classes for specific work types such as air conditioning installation, refrigeration work, or high-voltage work. Licensed electricians must maintain their licence through continuing professional development requirements and renewal processes specific to their jurisdiction. Unlicensed persons cannot perform any electrical installation work except for minor non-electrical tasks such as cable pulling under direct supervision, lifting and positioning of equipment (but not electrical connections), and general labouring. All electrical connections, testing, and commissioning must be performed by licensed electricians. Insurance coverage and building warranties typically require electrical work to be performed by appropriately licensed electricians, and supply authorities will not connect electrical services unless installation is certified by licensed electrician.

How do I ensure my electrical installation complies with AS/NZS 3000 Wiring Rules?

Compliance with AS/NZS 3000 Wiring Rules is mandatory for all electrical installations in Australia. Ensure compliance by first obtaining current version of AS/NZS 3000 Wiring Rules and any state or territory variations that apply in your jurisdiction. Engage electrical designers or consultants to prepare electrical designs complying with Wiring Rules requirements for complex installations. Follow Wiring Rules requirements for minimum conductor sizes based on circuit current capacity, voltage drop calculations, and protection device coordination. Install cables using approved installation methods specified in Wiring Rules including minimum support spacing, bending radius requirements, and segregation from other services. Ensure all electrical equipment is approved for use in Australia bearing required compliance marks. Conduct comprehensive testing as specified in Wiring Rules Section 8, including insulation resistance, earth continuity, polarity, and RCD operation testing. Maintain clearances from non-electrical services per Wiring Rules requirements including separation from plumbing, gas services, and communication cables. Install electrical equipment with appropriate IP ratings for environmental conditions where they are installed. Provide adequate working clearances in front of switchboards and electrical equipment per Wiring Rules requirements. Engage independent electrical inspection services to review installation compliance with Wiring Rules before commissioning. Complete electrical certificates demonstrating Wiring Rules compliance for submission to building certifiers and electrical safety regulators. Stay current with Wiring Rules amendments and updates through professional electrical associations and continuing professional development. For specialist installation types including hazardous areas, hospitals, or complex industrial installations, engage electrical engineers with specific expertise in these areas to ensure comprehensive Wiring Rules compliance.

What testing do I need to do before energising a new electrical installation?

Comprehensive electrical testing before energisation is mandatory under AS/NZS 3000 Section 8 and electrical safety regulations. Required tests include visual inspection of entire installation checking cable support and protection, termination security, circuit identification, and absence of obvious defects. Conduct insulation resistance testing using insulation tester (megger) applying 500V DC for circuits rated up to 500V AC, measuring resistance between active and neutral, active and earth, and neutral and earth. Minimum acceptable insulation resistance is 1 megohm for mains voltage circuits. Perform earth continuity testing from main earth bar to all outlets and equipment requiring earthing, verifying earth loop resistance does not exceed maximum values. Test polarity at all outlets, switches, and equipment connections verifying active, neutral, and earth are correctly connected with no reversals. Conduct residual current device (RCD) testing using RCD tester at multiple test currents (half rated trip current, rated trip current, and five times rated trip current), verifying trip times comply with AS/NZS 3000 requirements. For three-phase installations, verify correct phase rotation using phase rotation meter. Test all circuits for continuity and correct circuit routing before final energisation. Document all test results including test instrument details, circuits tested, results obtained, and electrician conducting testing. Rectify any test failures before energisation, conducting re-testing after remedial work. Provide test results to building certifiers as prerequisite for occupancy approval and to electrical safety regulators as required for permanent electrical connection. Progressive energisation testing involves energising circuits individually while monitoring for any abnormal conditions before full load application. Maintain test records for regulatory compliance and warranty purposes.

How do I coordinate electrical installation with other construction trades?

Effective coordination with other construction trades is essential for safe, efficient electrical installation. Begin by attending regular site coordination meetings with all trades working on project, identifying work area conflicts and sequencing issues before they occur. Develop coordinated services drawings showing electrical, plumbing, HVAC, fire services, and communication routes in ceiling cavities and service risers, identifying conflicts requiring resolution. Establish ceiling cavity access schedules specifying times when each trade can work in ceiling spaces, preventing overcrowding and allowing adequate work space. Mark electrical conduit routes on floor slabs before concrete pour, coordinating with concreters and steel fixers to prevent conduit damage during reinforcement and concrete placement. Install cable tray routes in coordination with HVAC duct installers and plumbing pipe installers, maintaining required separations and ensuring adequate space for all services. Establish notification procedures requiring trades to inform each other when working above other trades' work areas, allowing exclusion zones and overhead protection to be established. Implement damage reporting procedures requiring immediate notification of any damage to electrical services by other trades, enabling prompt repair and verification of electrical safety. Conduct joint inspections at roughin completion points with all trades present, verifying all services are installed without conflict and identifying any issues requiring resolution. Protect installed electrical services from damage by other trades using conduit guards, cable covers, and barricading around switchboards. Maintain regular communication with project managers, site supervisors, and foremen from other trades to stay informed of schedule changes and emerging coordination issues. Document all coordination activities in site diaries and project correspondence creating audit trail and accountability for coordination decisions.

What happens if electrical inspection fails and how do I rectify it?

When electrical inspections identify defects or non-compliances, systematically address issues to obtain approval. Review inspection report thoroughly understanding specific defects identified, Wiring Rules clauses that are not satisfied, and inspector's requirements for rectification. Prioritise critical safety issues requiring immediate attention including exposed live parts, incorrect earth connections, and inadequate circuit protection. Develop rectification plan documenting how each defect will be addressed, materials required, and timeline for completion. Assign licensed electricians to conduct rectification work ensuring appropriate supervision of any apprentices involved. Photograph defects before rectification and after rectification creating evidence of corrective work. Common rectification items include inadequate cable support requiring additional cable clips or straps, incorrect switchboard labelling requiring updated circuit schedules, insufficient earth continuity requiring additional earth bonding, RCD non-compliance requiring replacement with correct rated devices, and voltage drop exceeding limits requiring cable upgrades. After rectification is complete, conduct comprehensive re-testing verifying all defects are corrected and installation now complies with requirements. Document rectification work and re-testing results preparing for re-inspection. Contact electrical inspector to arrange re-inspection providing rectification documentation demonstrating issues have been addressed. For significant defects requiring extensive rework, consider engaging independent electrical consultants to review installation and advise on compliance strategies. Learn from inspection failures by reviewing installation practices, improving quality control procedures, and providing additional training where skills gaps are identified. Maintain positive relationships with electrical inspectors through professional communication and demonstration of commitment to compliance and quality. Budget projects appropriately allowing time and resources for rectification work as inspection failures are normal part of construction process and should be anticipated in project planning.
