The white wire must be attached to the trailer for the grounding and power supply of the lights. This is achieved by connecting the fixed earth wire to the earth terminal on the socket or switch and then connecting a short length of wire from this terminal to the earth terminal in the wall box.
How To Install A Plug Socket
Surface socket wiring diagram. Do this by connecting the new green ground wire to the existing ground wire at the first box see ground metal boxes and fixtures below. Use appropriate greenyellow sleeving if required.

No bare wire should be exposed. This is done by cutting the wire about half an inch back and attaching it to the shrink hose of the trailer. You must heat the surface with a heat gun and then drill a hole in the hose.
Changing a socket and adding a new one to a circuit are two of the few electrical tasks a diyer can legally do so take a look at its key components with this detailed diagram of the inner working of the humble electrical socket.
