As mentioned in a previous update, Type AC RCDs must not be installed in Australia after 30 April 2023.
We understand that there has been some discussion in industry about ERAC changing their view on the matter, and how this may affect the rules in WA. We have sought clarification on the issue from the WA Electrical Inspectors and can confirm the following:
The Electrical Inspectors will be enforcing the requirements of AS/NZS 3000:2018 (the Wiring Rules) clause 126.96.36.199.2 from 30 April 2023 for the following:
Works already under way and covered by a Preliminary Notice would be inspected as to the previous requirements.
Existing installations would not need to be updated to new requirements if works being carried out don’t require replacement, upgrading or altering of existing circuit protection. Like for Like replacements can’t occur after this date, as mentioned by Building and Energy.
The Wiring Rules states that the reason for this change is to cover the use of electronic devices which are becoming more common in their use, to cover both sinusoidal alternating current and residual pulsating direct current.
