[QUOTE="Geoff1946, post: 485928, member: 28452"] This needs careful thought due to the multiple permutations of operating conditions and faults which could occur. My initial thoughts are that an RCD needs to be at the external power input to protect all the vehicle installation. Second thought concerns the idea of a changeover switch. I think I would be more inclined to use two sockets and a plug on a short flying lead. One of these sockets would be from the invertor output and I think should also have an RCD. (Is the invertor output neutral grounded?) Finally I think there are regulations concerning mobile installations, but I don't have these and I don't know what's in them. The complete vehicle presumably constitutes a workplace, with the regulations that implies. Time for someone else to advise! [/QUOTE]
