Home / The three-level distribution box uses five-wire power distribution

The three-phase five-wire system includes three phase wires (A, B, C wires), neutral wire (N wire), and ground wire (PE wire) of three-phase electricity. When the three-phase load is symmetrical, the vector sum of the current flowing into the neutral. Many factories and businesses use these boxes to run things like motors, air compressors, and heaters. (1) Power distribution from the primary main distribution board (distribution cabinet) to secondary distribution boards can be branched; that is, one main distribution board may supply power via multiple branch circuits to several secondary distribution boards.
