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.Quote:

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.[bighmmm]

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. [bigrolf]
I know, "That'll be a 100 bucks Mr bee" Kerching.
I wouldn’t be too concerned about your oven ac and hws as long as your power and lights are protectedQuote:

Seperate RCBOs are the way to go so if you have a fault you only lose one circuit not half the house[emoji1531]

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