The answer to 'what is electrical panel' is an electrical panel, also known as a breaker box or service panel, is the central hub for your home's electrical system. It's the main distribution point where electricity enters your home from the utility lines and is then distributed to various circuits and outlets throughout your house.
The electrical panel contains a series of circuit breakers that protect your home's electrical system from overloads and short circuits. Each circuit breaker is responsible for a specific area or set of outlets in your home, and if there's an issue with that circuit, the breaker will trip to shut off power and prevent damage. Properly maintaining and upgrading your electrical panel is crucial for the safety and efficiency of your home's electrical system.
