I know installing a new circuit it has to be rcd protected, but how does this work on a minor works i.e an extra socket or a spur for a boiler?obviously this example is with a board with i.e a rewirable fuse board?.On a minor works what I am saying is would I have to put an rcd fused spur and an rcd socket front on the socket or dont you have to do this and put normal sockets and spurs on?Just like to clear it up?
