What is the primary function of a circuit breaker panel?

The primary function of a circuit breaker panel is to distribute electrical power to different circuits. This is a critical role within an electrical system, as the panel serves as the central hub for electrical distribution in a building or facility. It takes the incoming electrical supply and routes it into various branch circuits that provide power to different areas, appliances, and devices throughout the structure.

While the circuit breaker panel does provide overcurrent protection by using breakers to interrupt the flow of electricity in case of a fault, which is significant for safety, the main role remains the distribution of power. Additionally, the panel does not function as a performance monitor or connect multiple power sources directly. Performance monitoring typically involves other specialized equipment, and while some panels might allow connections for multiple supplies, their primary task is fundamentally about power distribution rather than the management of multiple sources.
