A distribution cabinet consists of a cabinet, protective grounding blocks, working grounds, intelligent monitoring devices, main circuit fuses, branch circuit breakers, and cable trays.
Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers.
Distribution cabinets are used in situations where the load is relatively dispersed and there are few circuits; motor control centers are used in situations where the load is concentrated and there are many circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.
