What is the role of a panelboard?

A panelboard serves a crucial role in electrical systems by distributing electrical power to various circuits. It acts as a centralized hub where electrical supply enters and is then directed into multiple branch circuits that serve different areas or devices within a building. The panelboard contains circuit breakers or fuses that protect these circuits from overload or short circuit conditions, ensuring safety and proper operation.

While options such as storing electrical energy, increasing voltage, and converting power types are important concepts in electrical systems, they do not accurately describe the primary function of a panelboard. A panelboard is not designed to store energy, increase voltage levels, or convert alternating current (AC) into direct current (DC); instead, its main purpose revolves around effective power distribution and protection of the circuits it serves.
