Hi can anyone advise me the easiest safest way to have a double socket and a light in my new build shed/summerhouse. I have a outdoor socket on back wall of house which is fed from a switched fused fuc in house. The shed is 6 metres from back wall. I know about armoured cable and depth of trench ect, could I change the fuc inside for a 30amp rcd spur or something similar... Anyhelp appreciated
