Hi all, need some advice on best way to go about wiring my shed.
Have fitted two sockets and a light and wired them all up to a two way metalclad RCD consumer unit. Now need to make the connection to the house consumer unit. This is the problem. The house has a split load consumer unit but there are no spare ways on the RCD side. I was going to just connect to the main switch side but then I realised that the underground cable would have no RCD protection.
Now I think I must change the consumer unit in the shed to a main switch type, then wire a seperate RCD in the house off the mainswitch side and wire the shed SWA cable to that. Is this method ok? If so, then I will wire the house end of the SWA cable to a metalclad RCD the wire that to the house main switch side of the consumer unit, with maybe 6.0mm T&E. Is this all ok?
Finally, I have heard that having two RCDs on a circuit can cause problems but as my second RCD will be on the main switch side I assume this will be fine?
Help comments and suggestions will be most welcome
Thanks
