GENERATOR TRANSFER SWITCH INSTALLATION SERVICES
Generator transfer switch installation is a core part of what Genstar does. We install and replace transfer switches for homeowners and businesses running standby generators and portable generators. If you bought a generator and have no safe way to connect it, this is the job that finishes it.
Our licensed electricians handle the full scope: sizing the switch to your service amperage, mounting it at the electrical panel, wiring the circuits, pulling the permit, and testing under load. We also get calls about switches someone else installed. Undersized units, loose connections, work that never passed inspection. Genstar will inspect what is there and lay out your options, whether that means correcting the install or replacing the switch.

Automatic Transfer Switch Installation That Starts Your Standby Generator on Its Own
Genstar installs automatic transfer switches alongside standby generators, and it is the setup most homeowners want. An automatic transfer switch for generator startup reads the utility line, fires the unit, and moves the house over without anyone touching a thing. You can be at work or asleep and the changeover still happens.
The install covers more than hanging a box. We wire the control leads between the switch and the generator, set the transfer timing, and confirm the unit picks up the load on a simulated outage before we leave. Most automatic installs back up the whole panel, which is why sizing against your service amperage matters so much here.
Manual Transfer Switch Installation and Inlet Box Wiring for Portable Generators
We install manual transfer switches for homeowners who own a portable generator. The work includes mounting an inlet box on the exterior wall, running the feed to the switch, and wiring a subpanel for the circuits you want covered.
That circuit selection is the part worth slowing down for. A manual transfer switch carries a shorter list than a whole-panel setup, so you choose what earns a slot: the well pump, the furnace or air handler, the refrigerator, a few lights and outlets. We label every one of them, so nobody is guessing with a flashlight during a storm.
Manual installs cost less than a standby setup and still keep generator power and utility power completely separate, which is what keeps backfeed off the utility line.
