2、 Introduction of lighting Small Power Distribution Board

1. Box structure

The main structure is divided into box shell, panel, mounting bracket, neutral bus bar, grounding bus bar and other components. There are opening holes for operating the main switch and shunt switch on the panel. If it is not necessary to install all shunt switches, the opening holes can be partially closed with sealing plates. The tapping holes of incoming and outgoing lines are placed on the upper and lower sides of the box shell. There are also long circular knockout holes on the back, which can be used after tapping according to the needs of users. Lighting Small Power Distribution Board can be divided into steel box, stainless steel box, iron box and plastic box according to the material of the box.

2. Main electrical components in the box and their protection functions

Miniature circuit breaker: used as main incoming switch or outgoing sub switch to provide overload and short-circuit protection for distribution lines. Disconnector: usually used as incoming switch for power on / off isolation. Leakage protector: generally, the leakage action current of 30mA is selected for the safety protection of personal electric shock. Surge protector: used to limit the lightning overvoltage conducted from the power line. The application and safety reliability of lighting Small Power Distribution Board. As a terminal power distribution equipment, the lighting Small Power Distribution Board is used in large quantities, and its safety and reliability concerns thousands of households, so it should be selected with great caution.

3. Select qualified and authentic products
