Disconnect wires

Disconnecting wires from an electrical socket is a potentially hazardous task that should only be carried out by someone competent with electrical work. If you are not confident, it is best to seek the services of a qualified electrician.

If you are disconnecting a socket from a ring final circuit, you can connect the ring within the existing box using a 30A connection block, joining live to live, neutral to neutral, and earth to earth. Then, fit a blanking plate to cover the socket. It is important to note that you cannot plaster over this connection.

If you want to remove the socket entirely, you will need to terminate all the wires in a junction box. This is typically done under the floorboards, using a maintenance-free junction box rated at 32 amp, such as the one made by Hager. Ensure that you do not use a standard junction box as these are not permitted in areas that are not easily accessible for maintenance, inspection, and testing.

If you are disconnecting a spur, you can disconnect the live, neutral, and earth wires from where they are supplied. If the socket will never be used again, you can remove the cable from the wall or cut it back, repairing any plaster damage. Alternatively, you can disconnect the spur to the socket and put the terminal ends into a connection block or cut or remove them completely.

Remember, before starting any electrical work, it is crucial to turn off the electricity for that area or floor and verify that there is no voltage present using a voltage tester or voltage detector pen. This will help ensure your safety and prevent accidental damage to other sockets on the circuit.

Use a junction box

If you want to remove an electrical socket entirely, you can terminate all the wires in a junction box. This is usually done with a 30-amp junction box under the floorboards, although it is possible to use a 32-amp box. If you are disconnecting a socket from the ring final circuit, you can connect the ring within the existing box using a 30-amp connection block, then fit a blanking plate.

Before starting any work on a junction box, it is important to prioritise safety. First, locate your home's circuit breaker and switch off the power for the circuit connected to the junction box. Use a voltage tester to confirm that the power is off. If you are unsure, consult a qualified electrician. It is also important to wear appropriate personal protective equipment, such as safety glasses, gloves, and rubber-soled shoes.

Once you have ensured that the power is off, you can begin to remove the junction box. First, assess its mounting and carefully detach it from its anchors, which may be nails or screws. If you are removing a metal box, you will need to remove a knockout for each cable that will enter the box. Use a screwdriver or hammer to break out the knockout, then twist off the metal disc with pliers. Install a cable clamp for each cable.

If you are removing the electrical socket entirely, you can either remove the cable from the wall and repair any plaster damage, or cut the cable back. Alternatively, you can disconnect the spur to the socket and put the terminal ends in a connection block, or cut or remove them completely.

Test for voltage

Testing for voltage is a crucial safety step before destroying an electrical socket. It is important to determine if the electrical system is powered and if any of its endpoints or waypoints have power. Testing an electric outlet can be done in several ways, ranging from simple and free methods to using expensive devices that employ radar waves.

One common tool used to test for voltage is a digital multimeter, a small electronic device used to measure electrical properties such as voltage, current, and resistance. It is also sometimes known as a multitester. A basic handheld multimeter meant for non-professional, at-home use typically costs between $15 and $50. To test an outlet with a multimeter, follow these steps:

  • Read the instructions that came with your multimeter before use, as different models may vary.
  • Set the multimeter to measure voltage.
  • Insert a probe into each slot of the outlet and read the line voltage measurement. A properly working outlet in the United States typically gives a reading of 110 to 120 volts. If there is no reading, check the wiring and the outlet.
  • To double-check, turn off the power, move the cap from one black wire to the other, turn the power back on, and test the uncapped wire.

Another tool that can be used to test for voltage is a voltage tester, often called a non-contact voltage tester. This tool can detect electrical current without touching exposed wires. Here are the steps to test voltage using a voltage tester:

  • Insert batteries into the voltage tester, ensuring they are fresh and facing the right direction.
  • Turn on the voltage tester.
  • Test the voltage tester on a working outlet by inserting the tip into the "hot" side of the outlet.
  • Return to the device or wire you want to test and hover the tip of the voltage tester about one inch from the wire. The tester will chirp and flash if a current is detected.

It is important to note that voltage testers are notorious for providing false positives and false negatives. Always test the voltage tester on a known live circuit before using it. Additionally, before working on any electrical system, shutting off the large breaker panel main switch will safely shut off any circuit you are uncertain about, but this will turn off all the power in the house. If you have any reservations about working with electricity, it is recommended to call an electrician.

Cap and cover

Capping and covering an electrical socket is a safe and code-approved way of dealing with terminated electrical cables. It is important to do so for fire safety, to prevent electrical shocks, and to prevent short-circuiting or damage to the electrical system.

Step 1: Shut off the power

Before you begin capping off electrical wires, shut off the power at the circuit breaker. Double-check that there is no electrical charge in the wires using a voltage tester. This step is crucial in preventing electric shocks.

Step 2: Prepare the wires

Use wire cutters to trim the ends of the wires until they are flush with their protective casing. Then, use wire strippers to strip away about one inch of insulation. Make sure you have about half an inch of clean, straight wire at the end.

Step 3: Cap the wires

Take a wire nut (also called a wire cap) that corresponds to the size and quantity of the wires you are capping off. Turn the wire nut clockwise onto the end of the wire. Use electrical tape to secure the wire nut to its respective wire. Be careful not to cap too many wires together.

Step 4: Install a blank cover

If the capped wires are in a device box, such as an electrical outlet box or junction box, install a blank wall plate or cover to comply with National Electrical Code (NEC) regulations. This step ensures that there is an indication to others that there are live cables present.

It is important to note that working with electrical sockets and wiring can be hazardous. If you are uncomfortable with any part of the process, it is best to hire a professional electrician to ensure the work is done safely and correctly.

Frequently asked questions

It is highly recommended that you get a qualified electrician to do this. If you want to do it yourself, you should first switch off the RCD circuit on your switchboard and retest to make sure it is off. Then, remove the faceplate, disconnect the wires, and put them into a Wago. Push the wires back in and put on a blank faceplate.

Terminate all the wires in a junction box under the floorboards, if possible. If you cannot do this, you can either remove the cable from the wall and repair any plaster damage or disconnect the spur to the socket and cut or remove the terminal ends.

Terminate all the conductor ends using a connection block, 20A or 30A.

You should use a voltage tester to make sure there is no voltage present. You can buy one for as little as £7.
