Adding a power socket

Adding an extra power socket will give you the freedom to enjoy your TV, video and computer without the hassle and in some cases added danger of using overworked multi-way adaptors and long extension cables. It shouldn’t be hard to fix a new socket if you follow our simple guide below. However, be safe and make sure that if your sockets are different shapes and sizes, old, or if the wiring itself looks old and brittle, get a professional in to do the job for you.

Things you’ll need

Circuit tester
Power socket mounting box
Power socket cover plate
Wire stripper

The steps to follow

  1. Turn off the mains power to the house.
  2. Unscrew and remove the electrical socket cover plate to expose the mounting box.
  3. Take out the mounting box from the wall hole. You should see three wires: the neutral wire (black wire), live wire (red wire), and grounding wire (blue wire).
  4. Use a circuit tester to see if the wires are live. Touch one probe of the tester to the neutral terminal and the other probe to the live terminal. The circuit tester will light up if the mains power is still on. Make sure that the power is turned off at the mains before continuing.
  5. Unscrew all fixings that are holding the wires to the terminals.
  6. Strip 1 cm (1/4 in) of the plastic insulation from the ends of the wires with a wire stripper.
  7. Attach the wires to the new mounting box.
  8. Make sure each wire is connected to the corresponding terminal. The black wire connects to the neutral terminal; the red wire connects to the live terminal, and the blue wire to the ground terminal.
  9. Wrap the wires around each terminal and tighten the screw with a screwdriver.
  10. Push the mounting box into the wall hole and secure it with screws.
  11. Replace the cover plate and turn the mains power on.
  12. Plug an electrical appliance to see if the new electrical socket works properly.
