Rcd discrimination

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.
