How To Wire a Plug

5
Your rating: None Average: 5 (2 votes)
Wiring a plug is a quick, simple DIY task which requires little knowledge and a bare minimum of tools.
What you'll need: 
New plug
Screwdriver (Phillips or flat)
Wire stripper/craft knife
Pliers
1: 
The most important element in wiring a plug is identifying the colours and relative names and functions of the three separate wires. The three wires are blue/neutral, brown/live and green & yellow/earth.
2: 
Using the Phillips or flat-headed screwdriver remove the plug cover. This will reveal the inside of the plug. You will find three separate 'terminals' with the right terminal containing the in-built fuse.
3: 
The method with which the wires are attached to the terminals varies according to plug type. There are two basic types; the first of which uses screws to hold the wires in place. The second type uses clips to secure the wires.
4: 
Having determined the attachment type, identify how much of the wires will need to be exposed in order to attach them to the terminals. Use the wire strippers to remove the necessary amount of insulating rubber and cut away any excess wire with the pliers.
5: 
If the plug uses screw attachments, loosen the screws sufficiently to allow the wires to slide through easily. The wires should be attached as follows: first attach the green & yellow/earth wire to the top terminal and ensure it is well tightened. Then attach the brown/live wire to the bottom right terminal and the blue/neutral wire to the bottom left terminal. The first two letters of the wire's names can be used as a mnemonic for their points of attachment.
6: 
Ensure that all three wires are safely secured and that there is no unnecessary loose wire within the plug. Where the main cable enters the plug there will be a bridge or two clips to secure the cable in place. Either clip the cable in place or screw the bridge closed over the cable.
7: 
Replace the plug cover before screwing it closed. Shake the plug gently to ensure there are no loose parts.
Conclusion: 
Wiring of a standard plug is a simple process. However, as mains electricity is extremely dangerous you should avoid the wiring process if you don't have the right tools or aren't confident that you can do it properly.
Tips: 
Remember BLue (bottom left) and BRown (bottom right).
Avoid over-tightening the screws inside the plug as this may break the wires.
