A distribution board (also known as panelboard, circuit breaker panel, breaker panel, 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 breaker for each circuit in a common enclosure.
[citation needed] With the use of non-CTL breakers, panels can be configured with the total number of circuits in excess of the designed capacity of that panel. The 2008 code did away with the previous 42 circuit limitation on panelboards. [3] One can now order panelboards with as many as 84 circuit places, and a corresponding ampacity rating.
