What is the primary function of an electrical panel?

The primary function of an electrical panel is to distribute electricity throughout a building and protect the electrical system from overloads. It serves as the central hub that connects the utility service to the various circuits within a structure. The panel contains circuit breakers or fuses that automatically disconnect the electrical supply in the event of an overload or short circuit, preventing potential fires and damage to devices. By managing and distributing the electrical load efficiently, the panel ensures that all circuits receive the appropriate amount of electricity needed for their operation, enhancing both safety and reliability in electrical systems.

Measuring energy consumption and storing electrical energy, while important functions within electrical systems, are not direct roles of the electrical panel itself. Similarly, converting direct current to alternating current is performed by specific devices like inverters and is not a function of the electrical panel.
