After a long thought I decided to position a power point outside for the MH. After getting all the cable, sockets etc. I then found out it needed a "qualified electrician" to either fit or sign off so I contacted said electrician who has just finished upgrading the old fuse box for a nice new consumer unit, checked if we needed a complete re-wire (fortunately not required as old (over 38 years old) wiring still has good insulation) and wired in the external socket. Today, plugged in the van to top up batteries and the whole lot has tripped in the house. Have been checking the van for faults and after consulting the handbook for my Autocruise Wentworth I find I have modified wiring. At some stage in its life it has had wiring for an inverter to be fitted and it seems somewhere between the mains input socket and the van consumer unit is a heavy duty relay (found behind the heater, accessed after removing 2 drawers.) I have had SWMBO indoors resetting the house trip (not circuit but main trip) every time I switch on the van circuit for heater, boiler, charger and fridge but the relay seems to be the culprit. I have an inverter which clips on the battery terminals and a fly lead plugs into the inverter giving power to lights, charger and sockets. I can only think this relay is there to avoid running the boiler and heater on inverted mains. Never had a problem with old fuse box at home nor when plugging in on site. Any ideas anyone please.
