What is an electrical installation safety checklist?

An electrical installation safety checklist is a verification document used to confirm that a new or modified electrical installation meets the requirements of AS/NZS 3000:2018 (Wiring Rules) before it is energised. It covers wiring methods, circuit protection, earthing, RCD installation, cable sizing, clearances, labelling and electrical test results. The completed checklist forms part of the compliance documentation required by state electrical safety regulators.

Is initial verification mandatory under AS/NZS 3000?

Yes. AS/NZS 3000:2018, Section 8.3 requires initial verification of every new electrical installation, alteration or addition before it is connected to supply. The verification must confirm that the installation is safe and complies with the Wiring Rules. In most Australian states, the installing electrician must also submit a certificate of compliance (or equivalent document) to the state electrical safety regulator. Failure to verify before energisation is a regulatory breach.

What tests are required for a new electrical installation?

AS/NZS 3000:2018 Section 8 requires insulation resistance testing on every circuit (minimum 1 megaohm at 500V DC), earth continuity testing, correct polarity verification, earth fault loop impedance measurement, and RCD trip time testing. Additional tests may be required depending on the installation type, such as phase sequence testing for three-phase supplies and prospective fault current measurement for switchboard ratings.

Who can sign off on an electrical installation?

In Australia, only a licensed electrician holding the appropriate class of licence for the jurisdiction can sign off on an electrical installation. The licence class required depends on the installation type and voltage level. The electrician must verify the installation personally, not rely solely on the work of apprentices or unlicensed assistants, and must submit the required compliance documentation to the state regulator.

How long should the installation verification record be kept?

Electrical installation verification records and certificates of compliance should be retained for the operational life of the installation as part of the building electrical records. AS/NZS 3000:2018 requires that verification documentation is available to support future periodic verification and any post-incident investigation. Most state electrical safety regulators require certificates of compliance to be retained for a minimum of 5 to 7 years, with longer retention recommended for commercial and industrial installations. The WHS Regulations 2011 also require that documents demonstrating duty of care be available for inspection by SafeWork, so storing the verification in the building file and the asset record in MapTrack is best practice.

What is a electrical installation safety checklist?

An electrical installation safety checklist is a structured document used to verify that a new or modified electrical installation meets the safety requirements of AS/NZS 3000:2018 (Wiring Rules) before it is energised and put into service. The checklist covers wiring methods, circuit protection, earthing systems, RCD installation, cable sizing, clearances, labelling and documentation. It is typically completed by a licensed electrician as part of the commissioning process and forms part of the compliance documentation submitted to the electrical safety regulator.

Electrical installation defects discovered after energisation are significantly more dangerous and expensive to rectify than those caught during a pre-energisation check. AS/NZS 3000:2018, Section 8.3, requires initial verification of every new installation, alteration or addition before it is connected to supply. The verification must confirm that the installation complies with the Wiring Rules and is safe for use. The WHS Regulations 2011, Regulation 147, requires that electrical installations are safe and properly maintained. Failing to complete a thorough installation checklist risks energising a non-compliant installation, which can cause electrocution, fire, equipment damage and regulatory prosecution.

What to include in a electrical installation safety checklist

This electrical installation safety checklist covers 10 key areas:

Installation details: site address, installation description, supply type (single-phase/three-phase), main switch rating, installation date.
Wiring methods: cable types used, installation method (conduit, tray, surface, buried), compliance with minimum bending radii and fill ratios.
Circuit protection: MCB/MCCB ratings match cable capacity, discrimination between upstream and downstream devices verified.
RCD protection: all required circuits protected by RCDs (AS/NZS 3000 Clause 2.6), RCD ratings and types correct, trip test results.
Earthing system: main earth electrode type and resistance, main earthing conductor size, MEN link (where applicable), earth fault loop impedance.
Cable sizing and voltage drop: cable sizes comply with AS/NZS 3008 for the installed load and route, voltage drop within 5% limit.

How to use this electrical installation safety checklist

Review the installation scope and gather reference documents: Obtain the electrical design drawings, specifications and any variation orders. Confirm the scope of the installation that needs verification: new circuits, modified circuits, switchboard changes. Have a copy of AS/NZS 3000:2018 and AS/NZS 3008 available for reference during the inspection.
Inspect wiring methods, cable installation and mechanical protection: Walk the installation and verify that cable types match the specification, installation methods comply with AS/NZS 3000 (conduit fill, bending radii, support spacing), and mechanical protection is provided where required. Check that cables are correctly identified with phase colours and circuit labels.
Verify circuit protection, RCD installation and earthing: At each switchboard, confirm MCB and RCD ratings match the design and cable capacity. Verify discrimination between upstream and downstream devices. Check the main earth electrode connection, MEN link, equipotential bonding and earth conductor sizing. Record earth resistance and loop impedance measurements.
Perform electrical tests and record results: Conduct insulation resistance tests on each circuit (minimum 1 megaohm), earth continuity tests, polarity checks, earth fault loop impedance measurements and RCD trip time tests. Record all results on the checklist and flag any readings outside AS/NZS 3000 or AS/NZS 3760 limits.
Complete documentation and issue the compliance certificate: Verify that as-built drawings reflect the actual installation, all test certificates are compiled and the switchboard directory is accurate. Record any outstanding defects, corrective actions and responsible parties. Sign the checklist with your electrician licence number and submit the certificate of compliance to the relevant state regulator.

How often should you complete this checklist?

An electrical installation safety checklist is completed once during the commissioning of a new or modified installation, before it is connected to supply. This is a mandatory initial verification under AS/NZS 3000:2018, Section 8.3. Subsequent periodic verification of the same installation should be performed at intervals determined by the installation type and environment, typically annually for commercial and industrial installations. Major modifications or additions to an existing installation require a new verification for the modified portions. In MapTrack, attach the installation checklist to the project work order and archive the completed record against the building asset for future reference.
