Distribution Boards & DBs

A distribution board (also known as panelboard, breaker panel, or electric panel) is a component of an electrical 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, the main switch, and in recent boards, one or more residual-current devices (RCD) or residual current breakers with overcurrent protection (RCBO), are also incorporated.
