A Detailed Explanation Of The Differences Between Distribution Boxes And Distribution Cabinets.
I. Conceptual Differences Between Distribution Cabinets and Distribution Boxes
1. Distribution Box
A distribution box is a small power distribution box containing power switches and fuses. It has a relatively simple structure and is mostly used for terminal power distribution. The distribution box is the last level of power distribution equipment in the power supply system. A distribution box can have one power input line and multiple power output circuits. Power output circuits are led from the distribution box to various electrical loads. Due to its small size, a distribution box cannot accommodate large electrical equipment, so its capacity is generally small. Typically, 4-8 small loads share one distribution box. Distribution boxes are located in the central area of the power load, and electricity is delivered to the loads via cables or wires.

A distribution cabinet is the next level of power distribution equipment above the distribution box. It is larger in size and can accommodate larger 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, generally ranging from a few kilowatts to tens of kilowatts. In addition to providing leakage protection and short-circuit protection, which are provided by traditional distribution boxes, it also provides functions such as overvoltage protection, arc fault protection, lightning protection, automatic power supply, temperature protection, power limitation, fault recording, self-checking function, learning and memory, mobile internet visualization, and digitalization.
II. Functional Differences Between Distribution Cabinets and Distribution Boxes
Simply put, a box that distributes electrical energy is called a distribution box. Distribution boxes are mainly used for controlling and distributing power to electrical equipment, and for protecting circuits against overload, short circuits, and leakage. Distribution boxes are installed in various places, such as schools, government offices, hospitals, factories, workshops, and homes, such as lighting distribution boxes and power distribution boxes. Distribution boxes are small in size and can be installed concealed in walls or stand on the ground.
Both distribution boxes and distribution cabinets are indispensable infrastructure in people's daily lives. Currently, some people are unaware of the importance of distribution boxes and cabinets, arbitrarily placing items on them or even maliciously damaging them, causing considerable damage to power distribution facilities and hindering the development of the power grid and circuit system. Wuxi Bo'er Electric specializes in the production of LED display intelligent distribution cabinets, PLC remote control distribution cabinets, multi-functional card distribution cabinets, construction site distribution cabinets, rental mobile distribution cabinets, XL-21 series power distribution cabinets, GGD low-voltage complete sets of distribution cabinets, various stainless steel distribution boxes and cabinets, wall-mounted control boxes, outdoor rainproof boxes, indoor distribution boxes, surface-mounted distribution boxes, concealed distribution boxes, and custom-made various non-standard boxes.
Differences between Control Boxes and Distribution Boxes
Control boxes are suitable for factories, mines, enterprises, shopping malls, hotels, schools, airports, ports, hospitals, high-rise buildings, residential areas, and other occasions, in low-voltage power grid systems with an AC 50HZ frequency and a rated operating voltage of AC 380V, for power and lighting distribution and motor control. They are suitable for indoor wall-mounted and outdoor floor-mounted power distribution equipment. Control boxes are also suitable for AC 50HZ power systems with a voltage below 500V for fire pump control, submersible pump control, fire fan control, fan control, lighting distribution control, etc. Control methods include direct start control, star-delta step-down start control, auto-transformer step-down start control, frequency converter start control, soft start control, and other control methods. Isolating switches and fuse-type switches can also be used as isolation points.
A distribution box is a low-voltage power distribution device formed by assembling switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. During normal operation, the circuit can be connected or disconnected using manual or automatic switches. In case of failure or abnormal operation, the circuit is cut off or an alarm is triggered by protective electrical appliances. Measuring instruments can display various parameters during operation, and can also adjust certain electrical parameters, providing prompts or signals for deviations from normal operating conditions. They are commonly used in various power generation, distribution, and substations.
