Breaker Panel

A distribution board (known in the United States as a (circuit) breaker panel, breaker box, panelboard, or load center or for old ones, fuse box) is a mounting enclosure for multiple electrical circuit breakers. These are generally placed in two columns. Small single-phase boxes, with the breakers in just one row, are known as consumer units in Britain. Distribution boards are typically found in central locations inside buildings and often serve as the point at which electricity is distributed within a building. Circuit breakers can be used to manually de-energize electrical circuits when the downstream wiring is being serviced.
