The difference between distribution box and distribution cabinet
I. Conceptual Distinction
1. Distribution Box
A distribution box is a small - sized power distribution unit that contains power switches and safety devices. It has a relatively simple structure and is mainly used for terminal power distribution. As the last - stage power distribution facility in the power supply system, a distribution box can have one power incoming line and multiple power outgoing circuits. The power outgoing circuits from the distribution box lead to various electrical loads. Due to its small size, large - scale power distribution equipment cannot be installed in it, so the capacity of a distribution box is not large. Generally, one distribution box supplies power to 4 - 8 small loads. Distribution boxes are installed in the central area of the power supply loads, and electricity is transmitted to the loads through cables or wires.
2. Power Distribution Cabinet
A power distribution cabinet is the upper - level power distribution equipment of a distribution box. It has a large volume and can accommodate large electrical equipment. Therefore, it is generally used as power distribution equipment for medium - capacity loads, including distribution boxes, motors, etc. Its applicable capacity varies in different industrial fields, usually ranging from several kilowatts to dozens of kilowatts. On the basis of providing leakage protection and short - circuit protection like traditional distribution boxes, it also offers functions such as over - voltage protection, spark - induced power cutoff, lightning protection, automatic power supply, temperature protection, power limitation, fault recording, self - inspection, learning and memory, mobile internet visualization, and digitalization.
II. Functional Distinction
Simply put, the box used for distributing electrical energy is called a distribution box. It is mainly used for controlling and distributing power to electrical equipment, and plays a protective role against overload, short circuit, and leakage of the lines. Distribution boxes are installed in various places, such as schools, government agencies, hospitals, factories, workshops, and households. Examples include lighting distribution boxes and power distribution boxes. They are small in size and can be installed concealed in walls or placed on the ground.
Both distribution boxes and power distribution cabinets are indispensable infrastructure in people's daily lives. Currently, some people fail to recognize the importance of distribution boxes and power distribution cabinets. They randomly place items on them and even intentionally damage them, causing significant damage to the power distribution facilities and hindering the development of the power grid and circuit system. Shenzhen Wuyi Lighting Equipment Co., Ltd. specializes in the production of LED display intelligent power distribution cabinets, PLC remote control power distribution cabinets, multi - function card power distribution cabinets, construction site power distribution cabinets, rental mobile power distribution cabinets, XL - 21 series power distribution cabinets, GGD low - voltage complete power distribution cabinets, various stainless steel distribution boxes and power distribution cabinets, wall - mounted control boxes, outdoor rainproof boxes, indoor distribution boxes, surface - mounted distribution boxes, recessed distribution boxes, and custom - made non - standard boxes of various types.
Difference Between Control Box and Distribution Box
Control boxes are suitable for use in occasions such as factories, mines, enterprises, shopping malls, hotels, schools, airports, ports, hospitals, high - rise buildings, and residential communities. They are applied in low - voltage power grid systems with an AC frequency of 50Hz and a rated working voltage of AC 380V, serving purposes such as power and lighting distribution as well as motor control. They are power distribution equipment suitable for indoor wall - mounting and outdoor floor - mounting. Control boxes are also applicable to power systems with an AC frequency of 50Hz and a voltage below 500V, used for fire pump control, submersible pump control, fire fan control, fan control, lighting distribution control, etc. The control methods include direct start control, star - delta step - down start control, autotransformer step - down start control, frequency converter start control, soft start control, and other control methods. Additionally, isolating switches and fuse switches can be used as isolation and breaking points.
A distribution box is a low - voltage power distribution device that assembles switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment on a closed or semi - closed metal cabinet or panel in accordance with electrical wiring requirements. During normal operation, the circuit can be connected or disconnected by means of manual or automatic switches. In case of a fault or abnormal operation, the protective electrical appliances will cut off the circuit or give an alarm. Measuring instruments can display various parameters during operation, adjust certain electrical parameters, and provide prompts or send signals when the system deviates from the normal working state. Distribution boxes are commonly used in various power generation, power distribution, and substation stations.
