Generator Installation

When the power goes out in a Wyoming winter, a properly installed generator is the difference between a minor inconvenience and a real problem.

Power outages in Wyoming are not a rare event. Between winter storms, high winds, and utility issues across rural stretches of the state, losing power for hours — or longer — is something Casper area homeowners and businesses deal with regularly. A generator solves that problem, but only if it's connected correctly. The electrical hookup behind a generator installation is what separates a system that works safely when the grid goes down from one that creates a hazard for utility workers or damages equipment when power is restored. Kevin Johnson has been handling generator electrical hookups in Casper, WY for over 35 years. He knows what a safe, code-compliant installation looks like and makes sure every job meets that standard.

The electrical side of a generator installation centers on the transfer switch — the component that safely disconnects your home or business from the utility grid before your generator takes over. Without a properly installed transfer switch, backfeed from a running generator can energize utility lines and put lineworkers at serious risk. It can also damage the generator itself when utility power returns. Aspen Grove Electric installs manual and automatic transfer switches sized correctly for the generator and the loads being backed up, whether that's a few critical circuits or the entire home. Kevin handles the full electrical scope of the installation from the panel connection through the transfer switch to the generator hookup point.

Whether you have a portable generator that needs a proper transfer switch connection or you're installing a standby unit that runs automatically, Aspen Grove Electric handles the electrical side of it correctly in Casper, Glenrock, Douglas, Mills, and the surrounding Wyoming area. A generator that isn't connected safely is a liability — not a backup plan. Call (307) 258-6849 and get the installation done right before the next outage hits.

Every installation Aspen Grove Electric completes meets those requirements — so the system is safe and the work passes inspection.
Honest Sizing Recommendations — Some generator installations get oversized or undersized because no one took the time to evaluate the actual loads being backed up.
