Wiring Rules

The new edition of the Australian/New Zealand Standard for Wiring Rules (AS/NZS 3000:2007) was released in November 2007 and revised by Amendment 1 in July 2009.

A Frequently Asked Questions and answers document has also been developed to explain some of the issues which have been raised by users of the Standard.

Produced by the joint Standards Australia/Standards New Zealand Committee EL-001, the revised edition expands on issues relating to electrical installations, improves safeguards and, addresses the needs and expectations of stakeholders.

The new edition, encompassing 450 pages, is now in a two-part format with improved layout.

  • Part One outlines fundamental safety principles and provides an ‘outcomes oriented’ approach to allow flexibility in design.

  • Part Two details ‘deemed to comply’ solutions to satisfy the Part One fundamental safety principles for the majority of electrical installation work.

The new edition is now more flexible, user-friendly and easier to read. It contains new definitions including the following terminology:

  • electrical installation;

  • circuit;

  • basic protection (protection against direct contact);

  • fault protection (protection against indirect contact);

  • outbuilding;

  • isolation; and

  • competent person.

Other key changes to the Wiring Rules Standard include:

  • the extended application of Residual Current Devices (RCDs) and testing for correct operation;

  • protection against arcing faults;

  • requirements for selectivity (discrimination) between circuits;

  • strengthening of requirements for the prevention of the spread of fire;

  • enhanced requirements for recessed luminaries;

  • requirements for sanitisation areas in the food processing industry;

  • inclusion of detailed guidance material removed from the 2000 edition; and

  • a more intuitive index, additional appendices, illustrations and background information.
