Only for socket outlets, which is fair enough, but I am questioning the requirement for the circuit supplying the sockets needing to be 30mA RCD

On a farm ? - I suspect not just due to the geography of the relevant outlets



So if we have a metal conduit drop shared by singles to a light switch and a socket, the socket circuit is more likely to develop a fault?

I suspect so - the lighting circuit will stop about 1.4m AFFL - the socket circuit will continue lower down and be closer to the wet nasty stuff, maniacs on machines with big forks, guys with barrows and the general abuse on farms.

Lighting switches are always best out of the way - sockets you can't do much about being in the space unless you want long leads with thier own risks.

Anyone got any other thoughts why it seems the circuit and the sockets need protecting by 30mA RCDs? Ta
