What is the purpose of an electrical panel?

The purpose of an electrical panel, often referred to as a breaker box or service panel, is to distribute electricity throughout a residential or commercial building while also providing circuit protection. It serves as the main hub where electrical power from the utility company enters and is then routed to various circuits that supply electricity to different areas and appliances within the structure.

The electrical panel houses circuit breakers or fuses, which act as protective devices that automatically interrupt the flow of electricity in the event of overloads or short circuits, thereby preventing potential hazards like electrical fires. This safety mechanism is critical for ensuring the safe operation of the electrical system and protecting both the property and its occupants.

In contrast, measuring electrical efficiency pertains to how effectively energy is used, which is not the primary function of the panel. Serving as a generator is not applicable, as electrical panels do not generate power but rather distribute it. Enhancing connection with the power grid could be relevant but is not the central role of the electrical panel itself; it primarily focuses on the distribution and safety within the building's electrical system.
