1. There is a common zero row:

A household distribution box with a common zero busbar, equipped with the following equipment: shared zero busbar, shared ground busbar, leakage protector, and air switch;

The main switch is a 2P leakage protector with leakage current, and the branch switches are all 1P air switches;

The wiring of the 2P leakage protector involves connecting one front and one neutral wire to the incoming line, and the same front and one neutral wire to the outgoing line; When wiring, follow the identification of the leakage protector for wiring; Connect to the upper port of the branch switch in front, and connect the neutral wire to the shared neutral bar;

The upper port of the 1P air switch is connected to the lower port of the 2P leakage protector. The lower port of the air switch only has one front terminal, which is connected to the circuit load. The lower port of the air switch does not have a zero terminal, and the zero wire is connected to the shared zero bar;

The ground wires are all connected to the ground busbar, and the box body including the distribution box should also be connected to the ground busbar.

2. No shared zero row:

There is no shared zero bar household distribution box, and the distribution box has the following equipment: 2P air switch, 1P leakage protector, and ground bar;

The main switch is a 2P air switch, and the 2P air switch is wired with one front and one neutral wire as the incoming wire, and one front and one neutral wire as the outgoing wire. When wiring, follow the identification of the air switch; Connect the front of the outgoing line to the upper port of the branch switch, and connect the zero line of the outgoing line to the upper port of the branch switch;

The upper port of the 1P N air switch is connected to the lower port of the 2P air switch. The lower port of the 1P N air switch has a front terminal and a neutral terminal, which are connected to the circuit load;

The lower end of the 1P leakage protector also has two terminals, separate from the front and neutral wires. When wiring, it is important to carefully read the markings on the leakage protector and not connect the front and neutral wires in the opposite direction;

The ground wires are all connected to the ground busbar, and the box body including the distribution box should also be connected to the ground busbar.
