Panelboards

An electrical panelboard is the central hub of a building’s electrical distribution system. It receives incoming power from the utility service or transformer and safely distributes electricity to individual branch circuits throughout a residential, commercial, or industrial property. Typically housed in a durable metal enclosure that is surface-mounted or flush-mounted on a wall, a panelboard contains copper or aluminum busbars that carry current, along with overcurrent protection devices such as circuit breakers or, in older installations, fuses. A properly sized and installed panelboard is essential for electrical safety, code compliance, and reliable power distribution.
