After the kitchen makeover. A supply for the microwave was needed as there was no 240 volt socket in the kitchen area. The extension cable used was not ideal.

The plan is to take the feed from an existing socket in the side dinette, under the floor to the base of the microwave cabinet.

The existing socket in the side dinette. I put it there to provide somewhere to plug a laptop, mobile phone charger or a small lamp.

After switching the mains off. Under the existing socket, the 240v supply (white wire). I drilled a pilot hole in the floor (marked with a blue wire) behind the wheel arch.

Also a pilot hole through the floor (marked by the yellow/green wire) in the position where the socket back box will go.

A hole just large enough for the 16 amp flexible cable drilled in the floor from below. The back box secured to the floor, wires stripped and tinned.

The socket all wired up. The microwave plug in place.

Where the cable goes through the floor it is cleated to the underside of the caravan. I followed the waste pipe and took the cable through...

...a knockout in the chassis, following the chassis member down to the rear of the wheel.

Same treatment to the end of the wire as before (stripped and tinned) and connected to the rear of the side dinette socket.

Switching on the mains and checked the dinette and the new socket for correct operation using a socket tester before...

...plugging in the microwave. It is obviously safer not having an extension lead trailling across the floor.
