In industrial environments, power equipment and electrical equipment are used very frequently. In order to ensure the normal operation and safety of the equipment, correct wiring is very important. This article details how to wire a four-prong industrial plug socket.

  1. Preparation
    Before proceeding with wiring, make sure you have the following tools and materials ready:

2. Remove the old socket

If you’re replacing an old outlet, you’ll first need to disassemble it. Use a screwdriver or wrench to unscrew the socket, and then gently pull out of the socket. Be careful not to use excessive force to avoid damaging the socket or wires.

3. Connect the cable

Peel off about 1 cm of the outer sheath from one end of the cable to expose the internal wires. Then, insert the wires into the corresponding holes in the socket. Usually, there are four holes on the socket, corresponding to the live wire, neutral wire, ground wire and protective ground wire. Make sure to follow the correct color coding, red is the live wire, blue is the neutral wire, and yellow and green are the ground wires.

4. Fix the cables

After inserting the cable into the outlet, use a screwdriver or wrench to tighten the screws on the outlet to hold the cable in place. Please be careful not to tighten too much to avoid damaging the cable. At the same time, make sure there is good contact between the cable and the socket to ensure good electrical conductivity.

5. Check whether the wiring is correct

After completing the wiring, it is recommended that you use a voltmeter to check whether the wiring is correct. Connect the two probes of the voltmeter to the live and neutral wires respectively, and observe the reading of the voltmeter. If the reading is close to the supply voltage, the wiring is correct; if the reading is much lower than the supply voltage, there may be a problem with the wiring and needs to be rechecked.

6. Install new sockets

Mount the wired outlet to the wall or appliance. Use a screwdriver or wrench to tighten the screws on the socket to make sure the socket is securely in place. Then, connect the other ends of the other three cables to the corresponding devices.

7. Use insulating tape

To ensure the safety and appearance of your wiring, you can wrap the wiring part with insulating tape. First, wrap the electrical tape around one end of the cable, covering the exposed wires and the screws on the socket. Then, continue wrapping the electrical tape until the entire wiring section is covered. Finally, use scissors to cut off any excess electrical tape.
