[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the terminal equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is suitable for occasions with relatively dispersed loads and fewer circuits, and the motor control center is used in occasions with concentrated loads and more circuits. They distribute the electric energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. The electrical components and lines in the distribution board should have good contact and reliable connection. There should be no serious heating or burning. The door of the distribution board should be intact; the door lock should be kept by a dedicated person, and the dust filter is generally installed at the air outlet of the distribution cabinet.
