Introduction

Sockets can either be surface-mounted or flush-mounted. While surface-mounted sockets are easier to install, flush-mounted sockets look cleaner and are less prone to accidental damage. Before adding a socket to your electric circuit, ensure that it complies with IEE electrical regulations and determine whether the circuit requires RCD protection.

Safety First

Electrical safety is paramount. Always follow these safety precautions before starting any electrical work:

• Switch off the main power at the consumer unit/fuse box and isolate the circuit you're working on by removing the fuse or switching off the breaker.
•  
• Attach a note to the unit to warn others you're working on the circuit.
• Check the circuit is dead using a socket tester or voltage tester/meter.
• Do not strain cables. If the cable cannot reach the new socket terminals, use a crimp or terminal block to extend it.

How to Replace a Damaged Socket

If a socket has been scorched, it's typically due to overloading or loose connections. It's essential to replace the damaged socket and fix the cause before using the appliance again.

Step 1: Isolate the Circuit

Begin by isolating the circuit. Use a socket tester to confirm that the socket is dead. Unscrew the socket faceplate and gently pull it away from the wall, keeping the screws in case the new ones don’t fit.

Step 2: Loosen the Terminal Screws

Loosen the terminal screws to free the cable cores. If the insulation has been damaged by heat, cut back the cores and strip the ends. Ensure the earth core is sleeved with green/yellow insulation if exposed, and connect the metal back box to the earth terminals of the faceplate.

Step 3: Connect the Wires

Connect the live (L), neutral (N), and earth (E) cores to the respective terminals on the new faceplate. Fully tighten the terminal screws, fit the new faceplate, and test the socket using a socket tester to ensure correct wiring.

How to Replace a Single Flush Socket with a Double Socket

If you have a flush-mounted single socket, you can easily upgrade it to a surface-mounted double socket. Here’s how to do it:

Step 1: Isolate the Circuit

First, isolate the circuit and use a socket tester to verify that the power is off. Unscrew the faceplate and disconnect the cables from the terminals of the single socket.

Step 2: Install the New Surface Mount Box

Remove the knockout from the new surface mounting box and pass the cables through. Mark the fixing holes, drill the wall, and plug the holes. Screw the new box in place.

Step 3: Connect the Wires and Fit the Faceplate

Connect the wires to the terminals of the double socket, then fit the new faceplate. Finally, use a socket tester to check that everything is correctly wired.

How to Flush Mount a Socket in a Solid Wall

Flush mounting a socket in a solid wall requires cutting a recess in the plaster and masonry. This job can get dusty, so make sure to wear protective goggles and gloves.

Step 1: Mark and Drill the Recess

Use a spirit level to mark the position of the mounting box on the wall. Then, drill a series of holes within the outline to a depth slightly greater than the box. Use a bolster and club hammer to break out the plaster and masonry.

Step 2: Fit the Box

Brush away debris and check the fit of the box. Mark the fixing positions, drill, and plug the holes, then fit the box into place. Make the final connections and use a socket tester to verify the wiring is correct.

How to Flush Mount a Socket in a Stud Wall

Flush mounting a socket in a stud wall is simple with a cavity fixing box. This box sits against the wall's face and is secured by lugs that press against the back of the plasterboard.

Step 1: Choose the Socket Location

Decide where to position the socket and use a stud finder to avoid the wall framework. Mark the box's outline with a spirit level, then cut out the plasterboard.

Step 2: Fit the Cavity Box

Remove the knock-out from the box and feed the cable through the opening. Push the securing lugs into place so they grip the plasterboard. Connect the wires and fit the faceplate. Use a socket tester to check the wiring.

Conclusion

Replacing or installing electric sockets can seem daunting, but by following these steps and prioritizing safety, you can complete the job confidently. Always use a socket tester to verify correct wiring, and if you’re ever unsure, it’s best to consult a professional.
