In the 3-phase distribution box, the MCCB is used as the main switch. Only Line terminals go through the MCBs. RCCB. In a newly constructed residential area, a 10kV power line is introduced into the substation. 4kV), power distribution is achieved through three levels of distribution boxes: the main distribution board, secondary. The distribution box (DB box) helps safely and efficiently distribute electrical power. In this board, balance load is distributed as. A distribution board (also known as panelboard, circuit breaker panel, breaker panel, circuit breaker, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit. A distribution board (often called a switchboard or panelboard) is an assembly that receives power from the main supply and distributes it to subsidiary circuits. It also provides protection against overloads, short circuits, and earth faults using circuit breakers and protective devices.
