AS/NZS 3760:2022 — In-Service Safety Inspection and Testing of Electrical Equipment and RCDs — Complete Reference

Purpose

This skill provides the complete text of AS/NZS 3760:2022, In-service safety inspection and testing of electrical equipment and RCDs, incorporating Amendment No. 1 (December 2022). It enables accurate clause lookup and compliance checking against the standard's requirements for the inspection, testing, tagging and documentation of electrical equipment in service.

AS/NZS 3760 is the primary Australian/New Zealand standard governing in-service testing of portable and stationary electrical equipment connected by flexible cord or connecting device. It specifies inspection procedures, electrical test methods (earth continuity, insulation resistance, leakage current, RCD operating time), pass/fail criteria, testing intervals by environment type, tagging requirements, competent person requirements, and documentation obligations. The standard is commonly referred to in the context of "test and tag" programmes.

Critical Rules

1. Only cite clauses that appear in the section files. Never fabricate or assume clause numbers, table numbers, or content.
2. Citation format: Use "Clause X.Y.Z" for individual clauses, e.g. "Clause 2.4.3.1 of AS/NZS 3760:2022". For tables, use "Table X.Y" e.g. "Table 2.1". For figures, use "Figure X.Y".
3. Use conservative, factual language when describing standard requirements. Describe what the standard requires in objective terms.
4. Always use Australian English spelling.
5. If a clause cannot be located in these files, state this explicitly. Do not guess or reconstruct clause content.
6. Distinguish between normative and informative content. Sections 1–2 and Appendices C, D, E, F, G and H are normative. Appendices A, B, J and K are informative. When citing appendix content, note its status.
7. Relationship with AS/NZS 3012: AS/NZS 3012 prescribes testing intervals for construction and demolition sites. AS/NZS 3760 prescribes the test methods. Where equipment is used on a construction site, AS/NZS 3012 testing intervals apply (typically more frequent than AS/NZS 3760 Table 2.4), and the tests are performed in accordance with AS/NZS 3760.
8. Relationship with AS/NZS 3000: AS/NZS 3760 does not apply to fixed equipment connected to installation wiring (which falls within AS/NZS 3000), except in Australia for RCDs installed in the electrical installation.
9. Note text extraction limitations. Tables, figures, and diagrams may not be fully preserved in the extracted text. If a query depends on specific table data or figures, advise the user to verify against the published standard.

Regulatory Standing

AS/NZS 3760 is a Category 2 — WHS Approved Code of Practice Reference. It is referenced in various WHS Codes of Practice (notably the Managing Electrical Risks in the Workplace Code of Practice) and by AS/NZS 3012 for construction site equipment testing methods. Compliance with AS/NZS 3760 provides a "safe harbour" for demonstrating that a PCBU has met their duty of care in relation to in-service testing of electrical equipment. Departure from the standard is permissible where the PCBU can demonstrate an equivalent or better standard of risk management.

For full regulatory context, including how this standard interacts with the WHS framework and how to frame compliance advice for different categories of standards, read ../../REGULATORY-CONTEXT.md.

Workflow

1. Identify the subject matter from the user's query — is it about testing intervals, test methods, pass/fail criteria, tagging, competent person requirements, or compliance checking?
2. For compliance framing: If the query involves regulatory consequences, gap analysis, or compliance advice, read ../../REGULATORY-CONTEXT.md to ensure the response correctly reflects the legal weight of this standard.
3. Read the relevant section file(s) — consult the Section Index above. For most queries, Section 2 will be the primary source.
4. For testing interval queries: Read Section 2, paying particular attention to Table 2.4 and Clause 2.2.
5. For test method queries: Read Section 2 (Clause 2.4.3) and the relevant normative appendix (D for earth continuity, E for insulation, F for transformers, G for power supplies, H for RCDs).
6. Cite clauses accurately from the extracted text.
7. Cross-reference with AS/NZS 3012 where the equipment is used on construction or demolition sites — AS/NZS 3012 prescribes more frequent testing intervals and AS/NZS 3760 prescribes the test methods.
8. Cross-reference with AS/NZS 3000 for matters relating to fixed electrical installations and RCD installation requirements.
