Hi, i have a problem with the 240 supply in my caravan. A toaster was plugged in and developed a fault (overheated) and The mains supply light went off. When i take the 2amp 240 supply fuse out, the mains light comes on, but when i replace it, the mains light goes out, the fuse appears to be ok. It seems as though there is a problem with the plug circuit, and connecting the plug supply via the fuse trips it off. There are two plugs, and both are affected. The fuses in the zig are all ok. There is a separate box (Hagen?) in the caravan which lights up ok, just seems to be the plug circuit. Does anyone know what has happened and how can i get the sockets working again, thanks, Tom
