Electrical news and updates

Electric cooking appliances and their isolation devices

Recently an electrical practitioner received an infringement notice from CBOS for:

  • Failing to connect the isolation switch for a range correctly, meaning that the range was not earthed; and
  • Failing to test the installation after energising their work, meaning the issue was not identified prior to putting the installation into service.

The practitioner and apprentice were doing the electrical fit out for a kitchen renovation. At the completion of the work the range was energised.

The TechSafe inspector who later inspected the work found that the range was not earthed.

The line earthing conductor for the range isolation switch was connected into the loop terminal of the isolation switch. The load earth conductor was connected into the earth terminal of the isolation switch. However, both were isolated from each other.

The electrical practitioner did not complete required testing of the range to ensure it was connected to the earthing system. Therefore the above issue was not identified, and the range was left not earthed. If a fault had occurred the range would have become live.

As a result, CBOS investigated the matter and issued the electrical practitioner with an infringement notice.

Australian Standard AS/NZS 3000:2018 (the Wiring Rules) Section 8 explains all of the minimum requirements for testing. You should also refer to the manufacturer’s installation instructions for isolation switches for information about the connection layout and the correct connection sequence.

Electrical Safety Bill consultation period closed

CBOS would like to thank anyone who provided a submission relating to the new Electrical Safety Bill 2020.

The Tasmanian Government is reforming and consolidating electrical safety laws, which have not been updated since the 1990s. The Bill consolidates the electricity safety laws, reduces duplication and improves flexibility in adopting and managing new electrical technologies as they develop.

We are pleased with the positive commitment to improving electricity safety in the state, as a number of well-considered and valued submissions have been received.

You can review the submissions on the Department of Justice website.
