Sub Panels

Sub Panel Upgrade Services

The main electrical panel and sub panel work the same way. The only difference is that the sub panel feeds of the main electrical panel when the electrical panel does not have enough space. If you are in need of a new electrical panel, it makes sense to upgrade your sub panel at the same time. And that’s where we come in! Our experts can handle a sub panel upgrade so you can live comfortably with all the electric power you need.
