[quote="kbrownie"]Whoever installed the socket, used a dry-lining backbox. These backboxes are designed to be sunk into hollow walls, not to be surface mounted.

They need to be swapped over, as the existing backbox will not conform to IP ratings from ingress protection of objects into the side of the box.
I would also be concerned over whether the flex supplying to socket is suitably rated to carry current safely and that it is not supported against stress.[/quote]

Gottcha!!! thanks for your input.
Cable is correct size supplied by caravan spares shop and same rating installed in caravan during manufacture.
Can't use house type pattress for same reason you cannot use one in a plasterboard cavity wall it'll fall out. It has to be like the one in the photo with a lip around the edge so when the screws of the socket are tightened the lips stop patterss falling through the hole.
I take all replies/ advice seriously and will ensure the box is protected as Electricity takes no prisoners. Its only fools who don't heed warnings.
Take a wall no reading but see a socket so chip carefully at plaster to reveal capping behing capping two 13amp cables (ring not spurt). That saved a melted drill bit and my hair didn't stand on end. Shiftted the shelf fixings i was putting up.
