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 divided into separate circuits to power different areas and devices throughout your house.
The electrical panel contains circuit breakers that protect your home's wiring by shutting off the power if there's an electrical overload or short circuit. This helps prevent fires and other electrical hazards. The panel typically has space for 8-42 individual circuit breakers, each controlling a different electrical circuit in your home.
