Windsor 4-way Distribution Board

A distribution board, also referred to as a panelboard, breaker panel, electric panel, DB board, or DB box, is a part of an electricity supply system that separates an electrical power feed into subordinate circuits and provides a protective fuse or circuit breaker for each circuit in a single enclosure. A primary switch is typically also included, and more recently, one or more residual-current devices (RCDs) or residual current breakers with overcurrent protection (RCBOs).
