What is the main function of an electrical panel?

The main function of an electrical panel is to distribute electricity throughout the building. This component is essential as it receives electricity from the utility company and routes it to the different circuits in the building, ensuring that power is delivered safely and efficiently to outlets, appliances, and other electrical devices. The electrical panel also contains circuit breakers or fuses that protect the circuits from overloads and faults, providing a critical safety feature in the electrical system.

In contrast, metering electrical usage typically involves separate devices known as electric meters, which track the amount of electricity consumed. The conversion of AC to DC power is performed by rectifiers or inverters and not directly by the panel itself. Storing backup power relies on systems like batteries or generators, which are not functions of the electrical panel. Thus, the electrical panel's primary role is indeed the distribution of electricity, making it vital for the overall functioning of a building's electrical system.
