A circuit breaker box, also known as a breaker panel or electrical panel, is a metal enclosure that contains electrical circuit breakers. These devices protect electrical circuits from damage caused by overcurrent, which can result from short circuits or overloads. Circuit breakers trip when the current flowing through them exceeds a predetermined level, interrupting the flow of electricity and preventing damage to the circuit and connected devices.
Circuit breaker boxes are an essential part of any electrical system, providing safety and protection for homes, businesses, and other buildings. They allow for the safe and easy isolation of individual circuits for maintenance or troubleshooting, and they can also be used to turn off power to specific areas of a building in the event of an emergency.
