The answer to 'how does electrical panel work' is an electrical panel, also known as a breaker box or service panel, is the central hub for your home's electrical system. It distributes electricity throughout your home and contains the main circuit breakers that control the flow of electricity to different circuits and appliances. The panel receives electricity from the power lines outside your home and then routes it to the various electrical circuits in your house.
Inside the panel, there are a series of individual circuit breakers that protect each circuit from overloading and tripping. When too much electricity flows through a circuit, the breaker will automatically shut off power to that circuit to prevent a fire or other electrical hazard. This helps ensure your home's electrical system operates safely and efficiently.
