The habitation report that was done on the motorhome in August 2016 noted that the 240v electric socket didn’t work when tested, so we knew it needed repairing. There were a few other jobs that needed to be done as well so we contacted a local mobile motorhome repairer.

no earth!
The strange thing is that under the worktop there is a factory fitted 240v junction box, this meant it was an easy fix with discreet wiring that can’t be seen.
We are safe now and it’s another job done.
