　　How to wire household distribution boxes

1. A distribution box shell, after production is completed, it looks like this;

2. The metal part in the middle is called the guide rail. If it is not installed at the factory, you can ask the merchant to install it for you. The installation is very simple, but it requires drilling holes. Individual households may not have such a small electric drill.

3. The upper row of screws is called the zero row on the left and the ground row on the right. If it is not equipped with a zero-ground row when it leaves the factory, you need to buy it yourself. The zero-ground row you buy looks like this.

4. The one on the left is called a ground bar (curved at both ends) and can be used directly; the one on the right is a zero row (straight) and needs to be used with insulated terminals. You also need to drill holes, you can ask the merchant to do it for you.

5. The ground wires of all sockets need to be connected to the ground bar. The neutral wire of the light needs to be taken from the neutral row (the live wire is taken from the 1P circuit breaker).

6. When wiring, you first need to arrange the circuit breakers in order.

7. After that, follow this sequence, install it on the bottom plate of the distribution box, and start wiring.

8. When wiring, you need to pay attention. The wires required for each circuit breaker need to be taken directly from the lower port of the upper level circuit breaker. Do not take the wires from the upper port of the parallel circuit breaker next to it. The wrong practices are as follows:

9. The correct method is as follows. If necessary, you can crimp the wire nose. If you don’t have a crimping plier, you can flatten it directly with a hammer, and then wrap a few turns with electrical tape between the wire nose and the wire insulation:

10. If you make your own distribution box, the craftsmanship may not be high, and it may not look good, but the safety of electricity must be ensured.
