Upgrading to a 1 gang USB socket
2.1.
To start, make sure you are familiar with the safety
warnings in this leaflet, the instructions supplied
with the product and the mains supply is turned off.
At the consumer unit, find the trip switch which protects
the circuit and turn it all the way off. The indicator
window should stay green.
4.3.
Test power is not supplied to the socket by using a plug in
socket tester or multimeter. Unscrew the retaining screws
on the socket so that it is released from the mounting box.
There will generally be three different wiring configurations.
This photo shows a single wire of each colour connected
to each terminal.

Alternatively, there could be two or three wires connected
to each terminal.
7.
6.
Whichever wiring configuration you find, unscrew each
terminal screw to release the wires. You should now
be able to remove the socket and place it to one side.
8.
If you find a metal back box with four fixing lugs, you will
need to bend back the lug on the top and bottom, to fully
fit the socket. Tools like a hammer and drift are suitable.
9.
Place the blue wire(s) into the neutral terminal, brown
into the live terminal and green/yellow into the earth
terminal. The terminals on the socket are colour-coded
to help locate the correct one.
11.
Line up the new socket and take note of where each
terminal is located.
10.
Make sure that the wires are fully inserted into the terminal
and that no bare copper wire is visible. Tighten the screws
securely onto the copper wire, not the outer sheathing.
12.
Gently press the socket back into place over the
mounting box. Take care not to trap any wires between
the wall and the socket.
Screw the retaining screws provided.
Use a spirit level to make sure that the socket is level.
Restore the power at the consumer unit and test.
