I am at a loss to see how powering up an extension lead can make the van live ???
Well it happened in France i plugged in to the mains as normal but some how the the wiring had been reversed and the rdb/d wasnt on the positive side plus the earth was live.Which is attached to the chasis of the van from the fuse box.
It was ok until i stepped out holding onto the camper i made the circuit to ground good job i had shoes on with a rubber sole, the camper being isolated by the tyres,
The Rcb/d never tripped.
I reckon i would have had a real belt (electricians term ) if i hadnt had shoes on.
I always check the supply with one of those LED gadgets that cost a few quid.
An extension lead is ok at home it has a circuit breaker in the house electrics which will trip.
Never presume anything
