We are in France and have probkem with the caravan electrics.
Lunar Clubman SB 2011.
Keeps tripping at bollard,
Found out that the RCD marked Fire and Sockets causes it to trip when I switch it to on.
The other RCD , Charger,Lights,Water heater, Fridge is OK.
I have made sure nothing is plugged into a socket.even the Microwave and oven fan.
Problem is I cant go around and plug something into each socket to see which one trips it because, when I flick up the Socket RCD it trips.
Any suggestions please?
