Changes to RCD Requirements

Written by

AICWA has contacted DMRIS to obtain additional information on the recent changes (Jan 1st, 2019)  so as to understand requirements for landlords, buyers and sellers.
DMIRs previously advised that:   
The 2018 edition of AS/NZS 3000:2018Electrical Installations (known as the Wiring Rules) is now available. The new standard has been developed by Standards Australia in collaboration with industry and government.

  • Previously in residences, all final sub-circuits supplying socket outlets and lights had to be protected with 30mA RCDs. In future, all final sub-circuits in residential dwellings must be RCD protected. No exceptions.
  • For non-residential, final sub-circuits up to 32A capacity supplying socket outlets must be 30mA RCD protected. Hard-wired equipment circuits of this capacity should be.
  • All lighting final sub-circuits must be RCD protected.
  • Alterations requiring a change to a circuit configuration trigger the requirement for 30mA RCD protection for that circuit. Like-for-like repairs do not.
  • Where all protection devices are replaced in a switchboard, all final sub-circuits must be RCD protected.
