Generator Installation Requirements

Most generator installations require an electrical panel upgrade to accommodate the transfer switch and additional load. If your home has an older 100-amp panel, we typically recommend upgrading to 200 amps as part of the project. Generator installations also require gas line connections — and as a licensed plumbing contractor, we handle that in-house. Many homeowners who install generators also add an EV charger at the same time to take advantage of the panel upgrade.

C.S.W. Power Solutions is more than an electrical contractor. As a licensed general contractor, we also provide plumbing and HVAC services in-house. Projects that require multiple trades — like home remodels or damage restoration — are managed under one roof for faster completion and lower cost.
