Understanding Subpanel Installation


A subpanel is a secondary panel that feeds off your main panel and distributes power to a specific area of your property, like a detached garage, a finished basement, a workshop, or an accessory dwelling unit.

Installing one is about extending your electrical system to a new location, not replacing or resizing what’s already there.

Subpanel Installation Process

We assess the space’s electrical needs and determine the right subpanel size, then run the feeder wire from your main panel to the new subpanel location. The subpanel is mounted, wired, and grounded correctly, with breakers installed for each new circuit. We test everything before finishing and handle permits and inspection where required.
