Lighting power distribution box equipment is a device responsible for completing electrical control, protection, conversion and distribution at the end of the low -voltage power supply system.It is mainly composed of wires, components (including isolation switch, circuit breaker, etc.) and boxes.
Lighting distribution box symbol
1) What are the lighting distribution box symbols in the lighting distribution box symbol: low -voltage lighting power distribution box Al, emergency lighting distribution box Ale, etc.2) Application of lighting distribution box symbols The application of lighting distribution boxes is roughly those aspects, mainly including electrical control, protection, conversion and distribution, etc.The application of the low -pressure lighting distribution box and emergency lighting distribution box is roughly the same. The main difference is that the key points are different. The lighting is mainly control and protection. The emergency is in conversion, allocation and control.In fact, they all have most basic applications.

Lighting power distribution box wiring diagram
When we first look at the power chart of the electric box, we must understand the basic design of the circuit diagram. The most important thing is not to confuse the zero line and the cable.It is also a very important level. The consequences of the error is that the power supply cannot be powered normally.But we dont have to worry too much about the serious consequences after receiving the mistake. The leakage switch will remind us.In order to allow us to better clarify the position of the neutral line and the fire line, people generally make marks on the leakage switch during design. The neutral line is marked with the letters of letters, so the position of the fire line is correspondingly found.When the application range of the power distribution box is different, the corresponding wiring method will also change.The home wiring chart we are talking about is a simpler compared to other complex wiring diagrams. People who have some understanding of physics will understand some of them. Those complex wiring charts need professionals to solve.The installation of the home power distribution box wiring first requires the user to buy the entry line, that is, the electricity plant is attracted from the power plant to the home. The house is almost 4 square meters.Next, the line of fire is connected to the switch of each room, and the fire line needs to be connected to the general switch, and the score is used publicly. As a result, the zero wire is allocated to each room to work mostly.
Lighting distribution box price
The price is mainly to look at the type of lighting distribution box: if it is a standard box (that is, PZ30) is about 100 ~ 200, if it is a non -standard box without a protective door (the one installed on the wall)~ 900, if the protective door is about 500 ~ 700, if it is a non -standard box without a protective door (the one installed on the ground) is about 1000 ~ 1500
