# Panelboard

A panelboard is a distribution panel with buses and overcurrent devices, set in a cabinet on a wall. The term is common in commercial work.

OSHA defines a panelboard as a single panel or group of panel units with buses and automatic overcurrent devices, with or without switches, built to sit in a cabinet in or against a wall and reached only from the front. Homes use the same idea in a [load center](https://danielelectric.multisites.ai/glossary/load-center).

Commercial buildings often have several panelboards, each feeding one part of the building. Some are fed from another panel, like a [subpanel](https://danielelectric.multisites.ai/glossary/subpanel). Service work on them needs a licensed electrician. See [commercial electrician services](https://danielelectric.multisites.ai/commercial-electrician).
