How To Wire A 3 Pin Plug

Wiring a 3-pin plug may seem like a complicated task, but with the right guidance, it can be a simple and straightforward process. In South Africa, it is important to ensure that your electrical connections are safe and secure to avoid any potential hazards. In this guide, we will walk you through the steps of wiring a 3-pin plug correctly, following the current industry standards.

Gather Your Materials

Before you begin, make sure you have all the necessary materials on hand. You will need a 3-pin plug, a screwdriver, wire cutters, and electrical tape. Double-check that the plug is suitable for the voltage in your region, as using an incorrect plug can lead to electrical issues.

Identify the Wires

When you look at the back of the 3-pin plug, you will see three terminals labeled “Live,” “Neutral,” and “Earth.” The live wire is usually brown or red, the neutral wire is blue, and the earth wire is green and yellow. It is essential to identify these wires correctly to ensure a safe connection.

Strip the Wires

Using the wire cutters, carefully strip the insulation off the end of each wire, making sure not to cut too deeply. You should have about 1cm of exposed wire at the end of each wire for connecting to the terminals.

Connect the Wires

Start by connecting the wires to the corresponding terminals on the plug. The live wire should be connected to the “Live” terminal, the neutral wire to the “Neutral” terminal, and the earth wire to the “Earth” terminal. Use the screwdriver to tighten the screws on the terminals securely, ensuring a good connection.

Secure the Connections

Once the wires are securely attached to the terminals, use electrical tape to wrap around the base of the wires and terminals. This will help to prevent any accidental contact with the wires and reduce the risk of electrical shock or short-circuiting.

Test the Plug

Before you plug in any devices, it is essential to test the plug to ensure that it has been wired correctly. Use a socket tester or a multimeter to check for continuity between the terminals and the wires. If the test indicates a successful connection, you can safely plug in your devices.

Final Checks

Once you have completed wiring the 3-pin plug, do a final check to make sure everything is secure and in place. Check that the wires are not exposed and that the plug fits snugly into the socket. If everything looks good, you can pat yourself on the back for a job well done!


Wiring a 3-pin plug may seem daunting at first, but by following these steps and guidelines, you can ensure a safe and secure electrical connection. Remember always to prioritize safety when working with electricity and consult a professional if you are unsure about any step in the process. With a little practice and attention to detail, you can successfully wire a 3-pin plug in South Africa.
