Up to the meter base and meter, the electrical system’s hardware is the property of a power utility company. The facility or building owner owns the wiring and equipment after that. The current is separated into distinct branch circuits from the main service panel, each of which is managed by a different circuit breaker.
A branch circuit is a component of the electrical system that runs from the main service panel and supplies power to the entire building. The main circuit breaker, which acts as the primary disconnect for the power supply to the main service panel, controls the main service panel. Two rows of smaller circuit breakers are located below the main one; these breakers serve as the start of the individual branch circuits that supply electricity to all regions of a facility.
