Information
I. Civil distribution box
 
1. The current power distribution facilities are divided into civilian and industrial use. The difference between the two is not very large. There are only two neutral wires and one live wire for civil households.
 
2. The identification of the live line at the incoming line is L. The identification of the neutral line is N. The general household distribution box consists of a main switch and several pink line switches. Generally, the main switch is equipped with leakage protection. The red wire is routed, and the neutral wire is blue, black, or yellow. If it is a single-switch power distribution switch, it must be connected to the live wire.
 
Industrial distribution box
 
1. Compared with civil power distribution facilities, industrial power distribution facilities are much more complicated. Industrial power is generally a three-phase 380V AC power. The incoming cables are four cables, three of which are live wires, one neutral wire, and cable wires. The path is also very thick ;
 
2. The incoming line of the industrial distribution box must have a main control switch, and then go out from the main line switch. If the machine used is very powerful, the line diameter of the sub-line must be thick enough;
 
3. The power distribution wiring of the industrial power distribution box is also very simple. The three live wires are connected to the input end of the air switch. The neutral wire is connected to the neutral wire of the machine lead. If 220V voltage is required, one of them can be led out as a live wire A neutral line from the neutral line.
