What is the function of an electrical panel?

The function of an electrical panel is primarily to distribute electrical power throughout a building and to provide overcurrent protection. It acts as the central hub where the main power supply enters the home or facility and is then distributed to different circuits. This distribution is done through circuit breakers, which serve to automatically shut off power to a circuit if there is an overload or short circuit, thus protecting the wiring and connected devices from potential damage.

While increasing voltage levels, measuring energy consumption, and connecting renewable energy sources are all important aspects of electrical systems, they do not define the fundamental purpose of an electrical panel. The main role is ensuring safe and efficient delivery of electricity to various parts of a structure while maintaining safety standards. Therefore, option B clearly encapsulates the essential functions of an electrical panel in managing and protecting the electrical distribution system.
