Replacing a Plug Socket

Never tackle an electrical job in your home unless you are absolutely certain you know what you are doing. If you are not sure about anything consult a qualified electrician. If you decide to replace a plug socket yourself you must buy a British Standard (BSI) product and follow the instructions which come with it to the letter. Advanced knowledge about the principles of household electricity is advisable for your own safety. Read below for some basic advice on fitting a socket.
Fitting a Socket
To fit a new socket you will need to break into the existing ring main or run a spur from an existing socket or from a junction box.Every socket on the power circuit has three connections with a circuit cable:
- The live core is linked to the socket’s live terminal - marked – Live – L.
- The Neutral core is linked to the neutral terminal - marked - Neutral – N.
- The bare earth is linked to the earth terminal - marked Earth – E - or the Earth Symbol ( ).
Safety
- Always turn off the mains switch before any electrical mains work.
- Double check the circuit is dead by plugging in an appliance or a mains tester.
- Use good quality materials which conform to British Standards.
- Use cables flexes, sockets and other equipment which conform to the correct rating of the circuits and appliances they serve.
- Follow all safety instructions provided by the manufacturer of the equipment you are using.
- If in doubt - contact a qualified electrician.


Step By Step
- Check core cables are the correct length and strip them with cable clippers.
- Ensure earth cable is insulated and marked.
- Connect the cables to the terminals on the back of the socket.
- Screw the socket to the mounting box.
