Amendment to Wiring Rules

Amendment to wiring rules

Amendment 1 of the 2018 edition of AS/NZS 3000 Wiring Rules has been released by Standards Australia.

The amendment includes several changes to the 2018 publication, including:

  • Clarification of sections Service Protective Device and Common Areas;
  • Updates to sections Luminaires, Appliances and Other Electrical Equipment and Special Electrical Installations;
  • References now include AS/NZS 5139, Electrical Installations – Safety of battery systems for use with power conversion equipment;

General Manager of Standards Australia Strategy and Engagement, Adam Stingemore said “This is an important standard for many within the electrical sector, with the protection and safety of workers at its core.”

“With the support of relevant stakeholders and industry, Standards Australia remains committed to keeping this standard up-to-date as we help build a safer and more resilient Australia,” concluded Mr. Stingemore.


The latest amendment also includes a major change to section 7.8 Standards for specific electrical installations. This section now references AS/NZS 5139 Electrical Installations-Safety of battery systems for use with power conversion equipment.

AS/NZS 5139 was published on 11 October 2019 and outlines the safety requirements for the installation of renewable energy battery storage equipment.

Designers and installers should consider using a pre-assembled integrated battery energy storage system (BESS) and pre-assembled battery system equipment (BS) that are shown to comply with the Best Practice Guide: battery storage equipment – electrical safety requirements, V1.0 2018.

The installation requirements in AS/NZS 5139 are streamlined for equipment that complies with the guide. Independent evidence of battery equipment complying with the guide could be a certificate from an Australian accredited certifier or be on an industry association listing such as the CEC approved batteries list.

There is also a transition period for AS/NZS 5139 until 1 July 2020 to allow electrical contractors and workers time to gain an understanding of the new standard. Battery systems installed after this date will need to comply with the standard. Enforcement action including notices and fines will be taken to address non-compliance.

Some regulators across Australia are permitting transitional arrangements for the new amendments. You should check with you State based electrical safety regulator for more information.
