When can an RCD be omitted from a domestic cable run

[Nigel]

Never have I or anyone I have ever worked with come across a refrigerator or a freezer responsible for a tripping RCD.

Complete myth.

Come on Neil you was always a better fisherman than that.

Sprinkler circuits are omitted too.
I don't read the regs book that much but i was sure that circuits passing through Zones 1 and 2 of a wet room need to be RCD protected as well as those supplying them.

Although I've yet to see cooker circuit trunked through a shower cubicle.

come the 18th all circuits with "lumimaires" need rcd protection..

do you mean loony mares?

I thought networked fire-alarm circuits should normally be on their own non-RCD circuit (6A MCB)?
Also feeds to subsidiary CBs (to avoid daisy-chained RCDs).

Hum, that depends on the type of cable used for the submain and the installation method
