The primary function of an electrical panel is to distribute electrical power to various circuits within a building or facility. This panel acts as a central hub that receives electrical energy from the utility company and then directs it to different circuits that supply power to outlets, lighting, and appliances throughout the area.

Electrical panels play a crucial role in ensuring that the power is safely and efficiently divided among different electrical loads, preventing overloads and ensuring that each circuit can operate within its capacity. The panel typically contains circuit breakers or fuses that protect each circuit from overload conditions, allowing for safe management of the electrical system.

While storing electrical energy, converting AC to DC power, and measuring electrical current are important aspects of electrical systems, these functions are more specific and do not encapsulate the main role of the electrical panel. The panel does not primarily store energy or perform conversions; instead, its key responsibility lies in the distribution of power.
