The three-level distribution boxes are respectively

The equipment within these boxes varies: primary distribution cabinets usually contain isolating switches, circuit breakers, and residual current devices (RCDs); secondary cabinets contain large three-phase circuit breakers; tertiary cabinets contain single-phase circuit. The equipment within these boxes varies: primary distribution cabinets usually contain isolating switches, circuit breakers, and residual current devices (RCDs); secondary cabinets contain large three-phase circuit breakers; tertiary cabinets contain single-phase circuit. The outgoing line from the low-voltage end of the transformer is 0. 4kV to the distribution cabinet (primary distribution cabinet), then the outgoing line is led to the distribution box (secondary distribution box) in each building, and finally the outgoing line is led to the distribution cabinet. The complete set of products can form a complete three-level protection system for construction power, so as to achieve the purpose of one machine, one switch and one protection. It is very suitable for all kinds of standard projects. The primary cabinet adopts lower incoming and lower outgoing. The third-level distribution box is the distribution box to which the cables drawn from the second-level distribution box are connected. Note: The three-level power distribution is mainly to ensure that each power-consuming device has electricity available; each power-consuming device can be used. The primary distribution box refers to the main distribution box, typically located in the distribution room. Main Distribution Board Serves as the primary.
