How to connect the nine bottom lines of the home kitchen circuit socket?

First of all, you need to figure out the polarity of each color power cord and connect it separately.

Different colors should have different polarities and cannot be articulated together.

After figuring it out, connect the live wire to the L connector of the socket, connect the neutral wire to the N connector, and connect the ground wire to the identification interface.

You can check the color of the power cord under the air switch in the switch, or find a voltage tester or multimeter to confirm the power supply.

According to industry regulations, brown or red is usually the live wire, the blue line is the neutral line, and the yellow and green two-color line is the ground wire.

According to the regular connection, the yellow-green wire is the ground wire, the red wire is the live wire, and the yellow wire is connected to the zero wire.

I feel that you have a zero-ground mess here, focusing on distinguishing the zero-ground wire. When the ground wire is zero, it will trip.

Of the nine wires, three should have come from the direction of the distribution box (and perhaps passed through other outlets), there were live wires, neutral wires, and ground wires, and the other six wires should have gone to the next two sockets. When connecting these three sockets, the live wire must be connected to the L hole of the socket, the neutral wire to the N hole of the socket, and the ground wire to the ground hole of the socket.

Here, the electrician is right to turn the nine wires into three, here should be wired according to what just said to the socket, to the other two sockets, should also be wired according to this requirement, if not wired according to this requirement, the air switch with leakage protection in the distribution box will judge the leakage and trip.

If you can't distinguish the live wire, neutral wire and ground wire, it is best to check it with a multimeter before connecting.
