howdy, I am running 22m. 4.0mm armoured cable underground to a workshop. This terminates at a 2 way cu protected by 40 amp 30 ma rcd with 1x 16 amp mcb and 1x 6amp mcb. I intend to install 5 double outlet sockets on a radial circuit and of course lights. My question is this: would the u/ground cable be adequately protected if was connected to a 32 amp mcb on the non rcd side of the house split load cu. The incomers on the house cu are an 80 amp dp switch and 100 amp 30ma rcd.
