The lighting distribution box is mainly used for lighting distribution of industrial and civil buildings, and can also be used for leakage, overload and short circuit protection of small capacity power lines. The lighting distribution box is a closed structure with small volume and good safety. It can be hung or embedded in the wall. The selected internal components include small circuit breaker, leakage switch, etc. some products are also equipped with watt hour meter and load switch. Generally, the way of incoming and outgoing lines from the lower side or upper and lower sides is adopted. The panel layout is required to be compact, neat, beautiful, safe and easy to maintain.

There are many manufacturers of power distribution box, which can't be listed one by one. Here we choose xxm-3 and xrm-3 lighting power distribution box. It is easy to install, dismantle and maintain. DZ47 series miniature circuit breaker is used as control and protection electrical appliance, which has novel structure, compact structure, superior performance and convenient installation and use.

The lighting distribution box is mainly used in high-rise buildings, hotels, airports, shopping malls, industrial and mining enterprises. It can be used as a lighting distribution device with rated working voltage of 220 V / 380 V and rated working current below 63 A. It can also be used as a leakage, overload and short circuit protection device for electrical equipment with rated working voltage below 63 a.

This kind of small power distribution box has two types: hanging type and embedded type, which are composed of box, panel mounting plate, component mounting frame, bus bar, neutral terminal block, protective grounding terminal and circuit breaker with different number. According to different needs of users, small doors can be added, and molded case circuit breaker adopts 35mm standard track mode, All DZ47 series leakage protectors and single pole circuit breakers are easy to disassemble, repair and replace.

The selection of circuit breaker in distribution box is introduced below;

① Main power switch. Dz47le-63-c60 leakage switch with leakage protection is selected for safety consideration;

② The kitchen, living room, room, toilet, TV, lighting, socket 1 and socket 2 are controlled in eight ways respectively, which is convenient for future maintenance and inspection. Dz47-60-16 ~ 20A can be selected for the eight single pole circuit breakers; There are no special requirements. Most families have enough.

Tips; Lead the live wire to the upper end (input) of eight single pole circuit breakers at the output side of the main leakage switch, and the cross-sectional area of the wire is more than 4mm? It can be connected by copper wire.
