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 that distributes electricity throughout your home. It's where the main electrical service line from the utility company connects and then branches out to the various circuits that power your home's lights, appliances, and other electrical devices.
Inside the electrical panel, there are multiple circuit breakers that act as switches to control the flow of electricity to each circuit. When too much electricity flows through a circuit, the corresponding breaker will 'trip' and shut off power to that circuit to prevent an electrical overload or fire. This helps protect your home's wiring and keep you and your family safe.
