Rcd discrimination

NGUACE
Any Information greatly appreciated.


Each outdoor socket has to be RCD protected, so if you have a junction box supplying more than one outdoor 30ma socket, how do you achieve RCD discrimination all the way back. I have an older C/U and the rcd on it is also 30ma?


A spur from internal plug to fused switch outside, which then feeds multiple outdoor sockets?


this is just a scenario I am trying to figure out.


thanks for anyone’s time.

    It’s not so much a problem but standards dictate the out side plugs are to be rcd protected, I am trying to figure out how you achieve this with multiple sockets?


    I think that there may be a misunderstanding here. You can protect a whole circuit or even installation with one RCD. You do not need to have sockets with built-in RCDs: in fact arguably that is no longer an acceptable way of achieving RCD protection.
