A subpanel is an electrical panel that is connected to a main electrical panel. It is used to distribute electricity to different parts of a building or structure. Subpanels are often used in large buildings or structures where there is a need for more than one electrical panel. They can also be used in smaller buildings or structures to provide additional circuits or to separate different types of electrical loads.
There are many benefits to using a subpanel. First, it can help to improve the safety of your electrical system. By separating different electrical loads onto different subpanels, you can reduce the risk of an electrical fire. Second, subpanels can help to improve the efficiency of your electrical system. By having multiple subpanels, you can better distribute the electrical load, which can help to reduce energy consumption. Third, subpanels can make it easier to troubleshoot electrical problems. By isolating different electrical loads onto different subpanels, you can more easily identify the source of a problem.
