What is a Subpanel?
A subpanel, also known as a secondary breaker panel or distribution panel, is an extension of the main electrical panel. It is typically used in larger residential or commercial properties to manage electricity distribution in areas that are distant from the main panel or require isolated circuits. Subpanels do not generate electricity; instead, they receive power from the main service panel and serve as localized control centers.
In practical terms, subpanels are helpful when renovating or expanding properties—for example, adding a garage, workshop, or outbuilding. By installing a subpanel in these areas, electricians can avoid the complexity and cost of running long circuit wires from the main panel. Subpanels help organize circuits and improve system safety, especially when dealing with high-load equipment. Each subpanel has its own set of breakers, making maintenance and troubleshooting more efficient.
