Tools and Materials Required

Before we delve into the process, let us first list the things that we need to ensure the job is done correctly.

  • A 3-wire plug
  • A screwdriver
  • A wire cutter/stripper

The Three Wires

A 3-wire plug comprises three wires, which are commonly colored green, white, and black. The green wire is the earth wire, while the white wire is the neutral one. The black wire is the live wire, carrying electrical current from the outlet.

Connecting the Wires

The first step in connecting a 3-wire plug is stripping the wires with the wire stripper to expose the internal copper wire. Each wire should be stripped to about 10mm in length.

The stripped wires should then be inserted into the 3-pin plug with their respective colors. The earth wire (green) should be inserted into the earth hole, the neutral wire (white) should be placed into the neutral hole, while the live wire (black) should be inserted into the live hole.

Using the screwdriver, the three terminal screws should then be screwed tightly to ensure a good connection that cannot be easily loosened.

Testing the Connection

After connecting the wires, plug the device into an electrical outlet and switch it on. If the device powers on, then the connection is successful, and the electrical device can be used.

There is no excuse for not being able to connect your electrical appliances safely and accurately.
