Electrical Panels & Load Centers — Phoenix, AZ
We stock a broad selection of electrical panels and load centers for residential and commercial applications — from 100A main breaker panels to 400A commercial load centers.
Buying Guide
Selecting the right electrical panel depends on your service size, number of circuits needed, and application. For residential use, 100A and 200A main breaker panels are most common. For larger homes or additions, 200A and 400A panels provide capacity for future growth. Sub-panels allow you to extend service to detached structures or add circuits to an existing installation. We carry both indoor and outdoor-rated panels, and our staff can help you spec the right unit for your project.
