Three-hole sockets are very common in life. This three-hole socket is safer and more reliable than two-hole sockets, so many people like to use three-hole sockets. So, let's introduce how to wire the three-hole socket and the precautions for purchasing the three-hole socket.
How to wire the three-hole socket
1. The three-hole socket has 3 power cords, the red one is the live wire, the green one is the neutral wire, and the black one is the ground wire. The size and diameter of the pins have great requirements, and the length and the distance between the pins are all factors to consider.
2. For single-phase electrical equipment, three-pin plugs and matching three-hole sockets can be used. The three-hole socket has a professional ground wire. When zero maintenance is selected, some often only connect the terminal of this hole to the zero wire introduced into the socket directly in the bottom of the socket, which is very dangerous.
3. Sometimes the neutral line of the power supply may be disconnected. This may be caused by the reverse connection of the live and neutral wires of the power supply, so that the metal shell and other metals will also carry the same voltage as the power supply, which may cause electric shock.
Three-hole socket purchase precautions
1. Choose the way
Go to regular large supermarkets, hypermarkets and other shopping malls to buy three-hole sockets and twin switched socket outlet, so that the quality is more guaranteed.
2. Recognize the brand

How to wire the wall switch socket
1. If the wall switch socket is used to control the power supply, you can first connect the live wire, then connect the switch L1 terminal and the L terminal of the two-hole socket, and then connect the neutral wire to the N terminal of the socket, so That's it.
2. If the double switched wall socket is used to control the lamp, you can first connect the live wire to the switch L terminal, then connect the switch L1 terminal to the lamp holder terminal, and connect the neutral wire to the other terminal of the lamp holder. The switch and the light form a loop. It is best to connect the live wire to the L terminal of the two-hole socket, and connect the neutral wire to the N terminal of the socket. The two-hole socket becomes another loop, and this is done.
This is the end of the introduction about how to wire the three-hole socket and the precautions for purchasing the three-hole socket. I hope it will be helpful to everyone.
