Method/Step
1. Before replacing the socket, be sure to turn off the circuit breaker of the socket. If you are not sure which circuit breaker controls the socket, turning off the main switch is the safest method.
2. The fixing screws are generally not visible on the exterior of the wall socket. You need to open the cover of the socket to see the screws. There are one or two small openings on the side of the cover, you need to use a flat-blade screwdriver to slowly pry open.
3. After opening the cover, you will find a screw on the left and right of the wall switch, you need to use a screwdriver to unscrew it.
4. After unscrewing the screws, do not rush to remove the wires with a screwdriver. First, use an electric pen to measure whether the circuit is live, and then unscrew the terminals after confirming that it is not live.
5. When replacing a new socket, the normal wiring method is the neutral wire on the left, the live wire on the right, and the ground wire on the upper side, which is often called “left zero and right fire”. The blue line is generally used for the zero line, the red line is generally used for the live line, and the yellow-green flower line is generally used for the underground. We just need to connect it according to the wiring method before disassembly.
6. After the connection terminals are tightened, screw the entire wall socket on the connection box, and buckle the cover on the socket body, which is beautiful and not easy to rust the screws.
