New Wiring Rules edition released

The new edition of the Wiring Rules (AS/NZS 3000:2018) has been released. You can purchase the new standard on the SAI Global’s website.

The new edition contains a number of changes from the previous 2007 edition including:

  • new requirements for safety switches
  • enhanced requirements for MEN earthing systems, including bonding of pool structures and wet areas
  • increased mechanical protection for cables installed within a ceiling space
  • additional installation requirements for electrical appliances, accessories and equipment
  • enhanced safety requirements for electrical equipmentinstalled in locations exposed to water
  • five new appendices:
    • continuity of supply for active assisted living
    • electrical conduits
    • installation of arc fault detection devices
    • guidance for the installation and location of electrical vehicle charging stations
    • DC circuit protection and switching devices.

To help identify the changes red asterisks have been added to the document to highlight areas which have changed.

A six month transition period will start on 26 June 2018. The transition period will allow electrical contractors and workers to access AS/NZS 3000:2018 Wiring Rules and gain a clear understanding of the changes to electrical installation requirements. These changes will need to be adopted into your businesses installation practices to ensure compliance with this new edition.

The enforcement date for AS/NZS 3000: 2018 Wiring Rules will be 1 January 2019. Electrical installation work carried out after this date will need to comply enforcement action, such as notices or fines, will be issued.

We appreciate there are a number of construction projects already commenced and it may be difficult to adopt the requirements of the new edition of the standard part way through an existing project.

The AS/NZS 3000:2007 Wiring Rules will continue to apply in these limited circumstances:

  • Electrical work commenced prior to but continuing beyond the publication date of the new edition of the standard.
  • Electrical work quoted prior to the publication date of the new edition of the standard that has been awarded a contract.
  • Significant electrical work costed and designed prior to the publication date of the new edition for major projects such as shopping complexes and large residential and industrial buildings.

During the transition period we encourage electrical contractors to comply with the 2018 edition where possible.
