If the regulations say that in a domestic situation where you have sockets (in a house) where you will connect appliances for use outside, like a lawn mower, you have to have the sockets with an RCD; is it the same to put the sockets on a circuit that will be connected to the RCD side of the consumer unit or do you still have to have the RCD at the socket? and in this case not put the circuit on the RCD side of the CU?
