What is a sub panel?

A sub panel is an additional circuit breaker panel that is connected to the main electrical panel of a building. It is used to create more circuits in a home or building without overloading the main panel. Sub panels are often installed in areas where additional circuits are needed, such as a garage, basement, or workshop.

Sub panels are wired to the main panel with a feeder cable, and they have their own set of circuit breakers to control the flow of electricity to the circuits connected to them. They are typically installed by a licensed electrician and must meet local building codes and safety standards.

Sub panels can help distribute electricity more evenly throughout a building, prevent overloading of circuits, and increase the overall electrical capacity of a home or building. They are a popular solution for homeowners and businesses looking to add new electrical circuits without the expense of upgrading the entire main panel.
