Any new installation
If replacing like for like, circuit protection has to be upgraded from rewireable fuses
If upgrading a switch board (complete replacement of fuses and circuit breakers) all final sub circuits must be protected with RCDs

Most commercial circuits,if not all,have RCD’s under a certain size,on new and upgraded installations.

Plays havoc with freezer rooms and cabinets that are full of heaters.
Insert doors are a real problem at times.
But with a good megga generally easy to sort when there is an issue.

And even an RCD will still give you a good boot before it trips,don’t ask me how I know.

Is this for Oz Wiring Rules or State?

RCDs on new circuits as/nzs 3000:2018

Switch board upgrades WA electrical requirements I think

Bugger, time to get a sparky to have a look & try to understand the Rules.


Board up graded aprox 30 years ago....... now 1x Main 2 phase RCD. Stove 2ph & Outdoor unit 1ph not in that circuit
Everything else miniature cct breakers. No separate RCDs. AC contains a Crankcase Heater.

HWS 1ph not covered by RCD but board is 1m from heater & in full view. Own CB.



Was added to when Digital Meters were installed by AGL a year ago. Meter Isolator & misc Solar gear. Board at Max Capacity & location will not allow a larger panel.


Maybe I should just leave it & it all may go away? A bit like Donald does.

I wouldn’t be too concerned about your oven ac and hws as long as your power and lights are protected

An ex electrical inspector I know upgraded his switch board before the new rules came in

Seperate RCBOs are the way to go so if you have a fault you only lose one circuit not half the house

Thanks Gav. That side is all ok then. Can you buy "plugin" RCDs as you could for Minature CB replacing fuses a few years ago?

Unfortunately not as the neutral needs to be wired through an RCD as well as the active.
