What is the power source of a circuit in a distribution box

A distribution box houses all the contact breakers, earth leakage units, doorbells, and timers. The electrical power supply comes from the network to the building through the main feeding cable. A power distribution box (also called PDU or distro) directs electricity from a main source to multiple circuits. It contains safety mechanisms like circuit breakers, neutral and ground bars, and wiring. 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. The di...

Distribution Boards

It serves as a centralized point where electrical energy from the main power supply is divided and directed to various circuits, controlling the distribution of electricity to different areas or appliances.
