The exposed wire should be about 1/4 inch long. If it’s too long, it could short out the circuit. If it’s too short, it may not make a good connection.
| Wire Type | Insulation Removal Length |
|—|—|
| Solid | 1/2 inch |
| Stranded | 1/2 inch, then twist and solder |Connecting the Wires to the Plug
Once you have removed the old plug, it is time to connect the wires to the new one. This is a relatively simple process, but it is important to do it correctly. If the wires are not connected properly, the plug will not work and could even be dangerous.
The first step is to identify the three wires: the live wire, the neutral wire, and the earth wire. The live wire is usually red or brown, the neutral wire is usually blue or black, and the earth wire is usually green or yellow.
Once you have identified the wires, you need to strip about 1 cm of insulation from the end of each wire. Be careful not to cut the wire itself.
Next, you need to twist the end of each wire together. This will help to keep the wires secure when you connect them to the plug.
Now, you can connect the wires to the plug. The live wire should be connected to the terminal marked “L”, the neutral wire should be connected to the terminal marked “N”, and the earth wire should be connected to the terminal marked “E”.
Once the wires are connected, you can tighten the screws on the terminals to secure them. Make sure that the screws are tight enough, but do not overtighten them.
Connecting the Neutral and Earth Wires
The neutral and earth wires are both connected to the same terminal on the plug. This is because they are both connected to the same point in the electrical system.
To connect the neutral and earth wires, simply twist them together and then connect them to the terminal marked “E” or “N/E”.
