A circuit breaker panel is an essential component of a home's electrical system. It houses multiple circuit breakers, which are safety devices that automatically shut off electrical circuits when there is an overload or short circuit. This helps prevent electrical fires and protects appliances from damage. The panel is typically located in a basement, garage, or utility room. Each circuit breaker controls a specific area or appliance in the home, such as lights, outlets, or large appliances like refrigerators and air conditioners. Regularly checking the panel can help ensure the electrical system operates safely and efficiently.
