By name: as-nzs-3000 description: "Technical reference for AS/NZS 3000:2018 (Wiring Rules). Use this skill when the user asks about Australian wiring rules, electrical installation requirements, earthing, RCD protection, switchboard design, or cable selection — or when an action skill needs to verify or cite specific clauses of AS/NZS 3000:2018."
AS/NZS 3000:2018 — Electrical Installations (Wiring Rules) — Complete Reference
Purpose
This skill provides the complete text of AS/NZS 3000:2018, Electrical installations (known as the Australian/New Zealand Wiring Rules), incorporating Amendments 1, 2, 3 and Ruling 1:2024. It enables accurate clause lookup and compliance checking against the standard's requirements for the design, construction and verification of electrical installations.
AS/NZS 3000 is the primary technical standard for electrical installation work in Australia and New Zealand. While not itself legislation, it is mandated by electrical safety laws across all Australian states and territories and by New Zealand regulations, making compliance effectively compulsory for all electrical installation work. The standard's requirements are intended to protect persons, livestock, and property from electric shock, fire and physical injury hazards.
The standard is structured in two parts. Part 1 (Section 1) sets out fundamental safety principles that shape minimum regulatory requirements. Part 2 (Sections 2–8) details deemed-to-comply solutions — specific work methods and installation practices that satisfy the Part 1 principles.
Critical Rules
- Only cite clauses that appear in the section files. Never fabricate or assume clause numbers, table numbers, or content. If a clause cannot be located in these files, state that the specific clause should be verified against a current copy of the standard.
- Citation format: Use "Clause X.Y.Z" for individual clauses, e.g. "Clause 2.5.3 of AS/NZS 3000:2018" or "Clauses 3.9.4.2 to 3.9.4.4" for a range. For tables, use "Table X.Y" e.g. "Table 2.2". For figures, use "Figure X.Y".
- Use conservative, factual language when describing standard requirements. Avoid subjective interpretation — describe what the standard requires in objective terms. Use "the standard requires" or "Clause X.Y specifies" rather than interpretive language.
- Always use Australian English spelling (e.g. behaviour, organisation, colour, defence, licence [noun], aluminium, metre, centre).
- If a clause cannot be located in these files, state this explicitly and indicate which section it is likely found in. Do not guess or reconstruct clause content from memory.
- Distinguish between normative and informative content. Sections 1–8 are normative (mandatory requirements). Appendices are informative (guidance material) unless specifically referenced as normative within the body text. When citing appendix content, note that it is informative guidance.
- Distinguish between the standard and legislation. AS/NZS 3000 is a technical standard, not legislation. WHS Acts and Regulations are covered by separate skills (whs-act-checker, whs-regulation-checker). The standard is called up by legislation but is not itself law.
- Note text extraction limitations. The reference files were extracted from a text conversion of the standard. Tables, figures, and diagrams may not be fully preserved. If a query depends on specific table data or figures, advise the user to verify against the published standard.

Regulatory Standing
AS/NZS 3000 is a Category 1 — Legislatively Mandated Standard. It is called up by state and territory Electricity Acts and Electricity Safety Regulations across all Australian jurisdictions, making compliance compulsory as a matter of law — not merely good practice. Non-compliance with AS/NZS 3000 constitutes a regulatory breach under the relevant jurisdiction's electrical safety legislation.
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
- Identify the subject matter from the user's query — is it a clause lookup, a compliance check, or a general question about the standard?
- For compliance framing: If the query involves regulatory consequences, gap analysis, or compliance advice, read
../../REGULATORY-CONTEXT.mdto ensure the response correctly reflects the legal weight of this standard. - Read the relevant section file(s) — consult the Section Index and Appendix Index above to determine which file(s) to read. For most queries, one or two files will suffice. Read only what is needed.
- For compliance checking: Read the relevant normative section first, then check whether the installation detail in question meets or departs from the stated requirements. Be specific about which clause applies and what it requires.
- Cite clauses accurately from the extracted text. Include clause numbers, table references, and figure references as they appear in the source files.
- Cross-reference where appropriate — some requirements span multiple sections (e.g. earthing requirements in Section 5 may interact with RCD requirements in Section 2 and damp situation requirements in Section 6).
- Flag limitations — if the query depends on table data or figures that may not be fully preserved in the text extraction, advise the user to verify against the published standard.
