# Breaker panel

A breaker panel, often called a breaker box, is the metal box that holds a home's circuit breakers and sends power out to each circuit.

Most people say breaker box. Trade terms for the same idea include [electrical panel](https://danielelectric.multisites.ai/glossary/electrical-panel) and [load center](https://danielelectric.multisites.ai/glossary/load-center). OSHA defines a panelboard as a panel that holds buses and automatic overcurrent devices, set in a cabinet in or against a wall and reached only from the front. Each [circuit breaker](https://danielelectric.multisites.ai/glossary/circuit-breaker) inside protects one circuit.

Never take the cover off yourself, because live parts sit behind it. Repair, replacement and upgrades are work for a licensed electrician. See the [guide to panels and service upgrades](https://danielelectric.multisites.ai/guides/electrical-panels-and-service-upgrades).
