Определение и Значение "subpanel"

What is a "subpanel"?

A subpanel is a smaller electrical panel that is connected to the main electrical panel of a building. It is used to distribute electricity to a specific area or section of the building, such as a garage, basement, or an addition. A subpanel helps reduce the load on the main panel and provides easier access to circuit breakers for specific areas, making electrical management more efficient. It is typically connected by a power cable to the main panel and can contain its own set of breakers for controlling power in the designated area.
