new socket on no rcd protected house

[kris jones]

Hi all,

A house has no rcd protection and im not able to change to an rcbo on the relevant circuit. A new CU is not an option.
A new socket is required in one room where the only other power source is on an opposite wall therefore I see the best option is to chase the wall out where the new socket is required and same where the old socket is to feed one form the other.

Regs state a depth of 50mm in order to comply with not having an rcd? seems a lot of work so I thought about an Rcd socket but that seems fine for anything plugged into the socket but what about the cable feeding it? if someone nails the cable it wont be protected.....

this scenario must come up time and time again... Is there a best practise?

Thank you in advance

you could fit a RCD FCU adjacent to the existing socket and then feed your new socket from that. this would have the result of protecting both the new socket and the cable.

Can an RCD mainswitch be fitted inline on the CU tails to cover the whole house?

I would initially suggest Tel's method or alternatively fit a standalone RCD near the CU and divert the socket circuit through the RCD.

Rcd main switch

Rcd fcu

Rcd enclosed adjacent to the board

Rcd protected sockets

There are quite a few options really
