Sub Panel installation

What is a Sub Panel?

In essence, an electrical sub panel can be thought of as a mini service panel. Its basic structure is the same as a service panel, with a main feeder wire leading into bus bars and circuit breakers. Branch wire circuits lead off of the circuit breakers into various parts of the house. There are 2 major reasons why you might want to install a circuit breaker sub panel:

  • If your main service panel does not have enough space to hold circuit breakers for any new circuits that you intend to install, the circuit breaker sub panel can, in a sense, create new space for circuit breakers, but in a physically separate location.
  • It's best to have a separation of service from the main electrical panel. Usually, a circuit breaker sub panel will service one separate area that has a discrete function, such as a kitchen, shop, office, or home addition. By installing a circuit breaker sub panel, you make it clear which circuit breakers and branch circuits apply to which parts of the house.
