AS/NZS 3000:2018 Electrical installations (known as the Australian/New Zealand Wiring Rules)
Standards Australia/Standards New Zealand
This Standard incorporates Amendment No. 1 (January 2020) and Amendment No. 2 (April 2021). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected.
The development of this edition was based on—
(a) new technology, new equipment and improved installation techniques;
(b) industry feedback regarding readability and compliance;
(c) identification and clarification of normative (mandatory) requirements and informative guidance material throughout the document; and
(d) experience gained in the application of the previous edition as expressed to Standards Australia and Standards New Zealand.
Amendment No. 2 includes text in Clause 220.127.116.11.2 that has transitional
implementation arrangements. Users of this document should consult with regulatory authorities to confirm the implementation dates of these requirements.
This Standard may be applied through legislative requirements, as indicated in Clause 1.2. This Standard supersedes AS/NZS 3000:2007 from its date of publication. This may not be practicable in some cases, and a transition period, e.g. 6 months, may need to be arranged. For example, where work on an installation was commenced before publication of this edition, the relevant regulatory authority or electricity distributor should be consulted regarding permission for the installation to be completed in accordance with AS/NZS 3000:2007.
The term ‘informative’ has been used in this Standard to define the application of the appendix to which it applies. An ‘informative’ appendix is only for information and guidance.
Part 1 provides provisions that constitute the minimum regulatory requirements for a safe electrical installation.
Part 2 provides work methods and installation practices that are ‘deemed to comply’ with the requirements of Part 1.
