What tests are included in electrical testing (IR, earth continuity, RCD)?

Standard electrical tests include: insulation resistance (IR) testing, which measures the resistance of insulation between live conductors and earth (typically must exceed 1 MΩ); earth continuity testing, which verifies that the earth path is intact and has low resistance (typically below 1 Ω); RCD (residual current device) trip time testing, which confirms the RCD trips within the required time (typically within 300 ms at rated current, 40 ms at 5x rated current); polarity testing, which confirms active, neutral and earth are correctly connected; and visual inspection, which checks for physical damage, correct wiring, appropriate ratings and labelling.

How often should electrical testing be done under AS/NZS 3760?

Testing frequencies under AS/NZS 3760 depend on the environment and equipment type. In hostile environments (construction sites, workshops, factories): test and tag every 3 months. In non-hostile commercial environments (offices, retail): test and tag every 12 months. New equipment in a non-hostile environment may be tested every 5 years. Cord sets and extension leads in hostile environments require testing every 3 months regardless. RCDs protecting socket outlets on construction sites must be tested daily (push-button test) and every 3 months (instrument test). Always check the current edition of AS/NZS 3760 and any state or territory variations.

What is an electrical test and inspection certificate?

An electrical test and inspection certificate is a formal document that records the results of electrical testing and visual inspection for portable appliances, fixed wiring installations or other electrical equipment. The certificate documents the tester details (name, licence, instrument calibration), each item tested with its results (insulation resistance, earth continuity, RCD trip time, polarity, visual inspection), the applicable standard (AS/NZS 3760 for portable appliances, AS/NZS 3000 for fixed wiring), and the tester's signed declaration that the results are a true record. It provides the audit trail needed to demonstrate electrical safety compliance.

Benefits of maintaining electrical testing records

Safety assurance: confirm that electrical equipment is safe for use and does not pose a risk of electric shock or fire.
Regulatory compliance: meet AS/NZS 3760 and WHS Regulation requirements for electrical safety in the workplace.
Audit trail: documented test results provide evidence for safety audits, WorkSafe inspections and insurance claims.
Failed item management: the certificate registers failed items with fault descriptions and actions taken (tag out, repair, dispose).
Scheduling: recording the next test due date for each item ensures nothing falls through the cracks.
Instrument traceability: documenting the test instrument serial number and calibration date ensures results are defensible.

What to include in an electrical test certificate

Our free electrical test and inspection certificate includes:

Tester details: date, tester name, licence/accreditation number, tester serial number, calibration date, site/location, client/company.
Items tested table: item number, description, asset ID/tag, voltage, visual inspection (P/F), earth continuity (Ω), insulation resistance (MΩ), RCD trip time (ms), polarity (P/F), overall result (P/F), next test due date.
Test equipment details: instrument make/model, serial number, calibration date and calibration due date.
Test standards: AS/NZS 3760, AS/NZS 3000 or other applicable standard.
Failed items register: description, fault details and action taken (tag out, repair, dispose).
Summary: total tested, passed and failed counts.
Tester declaration and signatures: tester certification and client acknowledgement.

How to use the electrical test certificate

Complete the tester details - your name, licence number, test instrument details, calibration date, site and client.
For each item, conduct a visual inspection first. Check for physical damage, correct wiring, appropriate ratings and labelling.
Perform the electrical tests: earth continuity, insulation resistance, RCD trip time (where applicable) and polarity. Record results in the table.
Mark each item as Pass or Fail based on the applicable standard limits. Record the next test due date.
For any failed items, complete the failed items register with the fault description and action taken (tag out of service, sent for repair, disposed).
Complete the summary totals and sign the tester declaration. Have the client acknowledge the results.

In MapTrack, you can digitise electrical testing with QR code asset tags, automated test scheduling and instant compliance alerts when items are overdue. Book a demo to see how.

Testing frequencies under AS/NZS 3760

Under AS/NZS 3760, testing frequencies depend on the environment and equipment type. Hostile environments (construction sites, workshops, factories): test every 3 months for cord-connected equipment and cord sets. Non-hostile environments (offices, retail): test every 12 months. New equipment in non-hostile environments: test every 5 years. RCDs on construction sites: push-button test daily, instrument test every 3 months. Always check the current edition of the standard and any state or territory variations. When in doubt, test more frequently rather than less.

Frequently asked questions

What is an electrical test and inspection certificate?: An electrical test and inspection certificate is a formal record of the testing and inspection results for electrical equipment or installations. It documents the tests performed (insulation resistance, earth continuity, RCD trip time, polarity), the results obtained, and whether each item passed or failed. The certificate is used for portable appliance testing (test and tag), fixed wiring inspections, and electrical safety verification. It provides evidence that electrical equipment has been tested by a competent person using calibrated instruments and meets the requirements of the applicable Australian Standard.
