What is the primary function of an electrical panel?

The primary function of an electrical panel is to distribute power to different circuits. An electrical panel, also known as a breaker box or distribution board, serves as the central hub for electrical distribution within a building. It receives electrical power from the utility service line and divides that power among various circuits that lead to different areas or appliances within the building, ensuring an organized and safe distribution of electricity.

Each circuit in the panel is equipped with a breaker that provides overcurrent protection, cutting off the electrical flow if it exceeds safe levels. This setup not only improves safety by preventing overloads but also allows for the individual control of electrical supply to different parts of the property. Therefore, the primary role of the electrical panel is crucial for effective and reliable electrical system management.

The other options do not accurately reflect the main purpose of an electrical panel: while it indeed provides a power source and may be involved in measuring current indirectly through the breakers, those functions are ancillary to its primary role of distribution. Moreover, it does not store electrical energy but rather acts as a point of distribution for incoming power.
