A main service panel, also known as an electrical service panel or circuit breaker panel, is a box that houses the main electrical service entrance for a building or residence. It is the primary distribution point for electrical power in a home or building, and it typically contains circuit breakers or fuses that protect the electrical system from overload and short circuits. The main service panel receives electrical power from the utility company's power lines and distributes it to the various circuits throughout the building. It is usually located in a basement, garage, or utility room, and it is typically labeled to identify the circuits that it controls.
