1. There is a public zero row:
There is a household distribution box with public zero discharge, and the distribution box has the following configurations: common zero row, common ground row, leakage protector and air switch;
The main gate is a 2P leakage protector with leakage, and the sub-switches are all 1P air switches;
The 2P leakage protector is wired, the incoming line is connected to a live wire and a neutral wire, and the outgoing wire is also a live wire and a neutral wire; the wiring is connected according to the logo of the leakage protector; the live wire is connected to the catch of the sub-switch , the zero line is connected to the common zero row;
For the 1P air switch, the upper port is connected to the lower port of the 2P leakage protector. The lower port of the air switch has only one live wire terminal, and the live wire is connected to the loop load. The lower port of the air switch has no neutral wire terminal, and the neutral wire is connected to shared zero row;
The ground wires are all connected to the ground row, and the box including the distribution box should also be connected to the ground row.
2. There is no shared zero row:
There is no household distribution box with a shared zero row. The distribution box has the following configurations: 2P air switch, 1P leakage protector, and ground row;
The main switch is a 2P air switch. The 2P air switch is wired. The incoming wire is connected to a live wire and a neutral wire. The outgoing wire is also a live wire and a neutral wire. When wiring, wire according to the logo of the air switch; outgoing live wire Connect to the upper port of the sub-switch, and connect the neutral line of the outlet to the upper port of the sub-switch;
For the 1P+N air switch, the upper port is connected to the lower port of the 2P air switch. The lower port of the 1P+N air switch has a live wire terminal and a neutral wire terminal, and the live wire and the neutral wire are connected to the loop load;
1P leakage protector, its lower port is also two terminals, which are connected to the live wire and the neutral wire respectively. When wiring, you should see the mark on the leakage protector, and do not reverse the live wire and the neutral wire;
The ground wires are all connected to the ground row, and the box including the distribution box should also be connected to the ground row.
