What is the name of the distribution box
A distribution box, or DB box, is a circuit breaker enclosure. It is a vital part and central hub of any electrical system. The hub distributes electrical power from a single input source to various circuits throughout a building. 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. Electrical systems power our homes, offices, and industrial facilities, but behind every reliable electrical setup lies a crucial component that often goes unnoticed: the distribution box. This essential piece of equipment serves as the nerve center of your electrical system, managing power flow. Also known as a distribution board, it's responsible for distributing the electrical power throughout the home or building with which it's used.
