The difference between a distribution box and a distribution cabinet
- Conceptual distinction
- Distribution box
A distribution box is a small power distribution unit that contains a power switch and a fuse device inside. Its structure is relatively simple and it is mostly used for terminal power distribution. The distribution box is the last level of power distribution facility in the power supply system. A single distribution box can have one power input line and multiple power output circuits, which lead to various electrical loads. Due to its small size, a distribution box cannot accommodate large-scale power distribution equipment, so its capacity is generally not large. Typically, one distribution box serves 4-8 small loads. The distribution box is arranged in the central area of the power load, and electricity is delivered to the load through cables or wires.
- Power distribution cabinet
The distribution cabinet is the upper-level distribution equipment of the distribution box, with a larger volume that can accommodate larger electrical equipment. Therefore, it is generally used as a distribution device for medium-capacity loads, including distribution boxes, motors, etc. Its applicable capacity varies across various technological fields, generally ranging from several kilowatts to tens of kilowatts. On the basis of providing leakage protection and short-circuit protection like traditional distribution boxes, it also offers functions such as overvoltage protection, sparking power cut-off, lightning protection, automatic power supply, temperature protection, power limitation, fault recording, self-checking function, learning memory, mobile internet visualization, and digitalization.
II. Functional differentiation
In simple terms, the box that distributes electrical energy is called a distribution box. Distribution boxes are primarily used for controlling and distributing electrical equipment, and for protecting lines against overload, short circuit, and electrical leakage. Distribution boxes are installed in various places, such as schools, institutions, hospitals, factories, workshops, and homes, including lighting distribution boxes and power distribution boxes. Distribution boxes are small in size and can be concealed within walls or erected on the ground.
Both distribution boxes and distribution cabinets are indispensable infrastructures in people’s daily lives. Nowadays, some individuals fail to recognize the significance of these facilities, randomly placing items on them, or even maliciously damaging them, causing significant damage to the distribution infrastructure and hindering the development of the power grid and electrical system.
