Please tell me, how would a switch-board mounted RCD or RCBO, be hooked up if you where connecting it up?.
Over here, we use a segregated Neutral busbar, for all of the load side Neutral conductors and the Lineside are connected to the Main Neutral Bus.
Your input please-

Cut-and-paste from the instructions:

Or did you mean the other way around? Feeding an RCD from the switchboard?

Exactly the same in South Africa. I think I've posted on this before but I cannot find it right now. GFCI required for all sockets and detached garage. Not required for lights, stove, water heater, hence two neutral busbars.

The same sort of split-neutral-bus panels have become common here as well. The RCD-protected circuit neutrals must be wired separately from the non-protected loads otherwise the breaker will just keep tripping.

A common arrangement here for new installations using TN-S or TN-C-S supply systems is for lighting and a couple of other "essential load" circuits, e.g. freezer/fridge or heating controls, to be on the line side and everything else to be fed through the RCD.

On TT systems that would necessitate the use of two RCDs. It's more usual to just see a single bus panel with a single main RCD on TT systems.

Simple thing in Austria: Main neutral directly to GFI/RCD, then wire links to 2pole breakers. With a 3ph setup (probably) 1 ph loads as described, neutral bus bar for 3 ph loads. If the panel is cheap (single pole breakers), neutral goes directly to the RCD, then to a neutral busbar.

Thanks for your replies, there guys,
the new Wiring rules(referenced to Australia), require all circuits, exceptions
are Ranges and Water Heaters, to be protected by a 30mA RCD,exceptions are because of the leakage currents associated with these loads. [Linked Image]
