a distribution board (also known as panelboard, breaker panel, electric panel, db board 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 breaker for each circuit in a common enclosure. normally, a main switch, and in recent boards, one or more residual-current devices (rcds) or residual current breakers with overcurrent protection (rcbos) are also incorporated.
