Subpanel Installation

Adding on? Extending? Don’t overlook your electric system! Add a subpanel to manage electricity for the new addition.

Extend your electricity’s reach.

A subpanel is a small service panel that distributes power to a specific area. It’s an extension of electrical service from the main electrical panel. Installing a subpanel may look easy, but you’re better off bringing in an electrician to do it safely.
