Generators & Transfer Switch Installation
Power outages in Maine can happen year-round. ACS Electrical Contractors offers professional generator and transfer switch installation for both portable hookups and fully automated standby systems, ensuring your home or business stays powered safely and reliably.
Overview
Generator installation is less about the generator itself than about the switching gear and the feeder behind it. A generator plugged into the wrong point in the service can backfeed the utility, damage the unit, and injure the line crews working to restore power. The work we do wires the generator into the service the right way through a proper transfer switch or interlock kit so the house or building can run on backup power without risk to anyone.
What you choose to back up is the other half of the decision. A portable generator tied to an essentials panel can keep the well, the freezer, the heat, and a few lights running through a long outage at a fraction of the cost of a whole-home solution. A permanently installed standby generator with an automatic transfer switch keeps everything on, starts itself inside of a minute, and never asks you to drag a cord through the snow. We size and specify both, and we are honest about which one fits a given property.
From Hookup to Code-Signed Install
We assess the service, the load, and the fuel supply before specifying a single unit. A portable setup with an inlet box and a mechanical interlock on the main panel is the most affordable path and works well for owners who are comfortable starting a generator and flipping breakers manually. A standby unit Generac, Kohler, Cummins, or similar needs a concrete or composite pad, a fuel line from a propane tank or utility gas meter, an automatic transfer switch sized to the service, and a load-shedding controller if the generator is smaller than the house demand. Each piece has code requirements that matter.
Once the hardware is settled, we pull the conductors, land the transfer switch, bond everything to the grounding-electrode system, and coordinate the startup with the generator technician for fuel-up and commissioning. Local permits and inspections are part of the job we pull them, schedule them, and walk the inspector through the install. We also review the expected outage behavior with you so there are no surprises the first time the power goes out at two in the morning.

Serving the Lewiston-Auburn Area
Greene, Monmouth, Wayne, and Winthrop sit on the kind of rural feeders that can be the last part of the map to come back online after a January ice storm or an October wind event. For a working farm, a home office with a server, a finished basement rental unit, or an aging-in-place household that depends on a well pump and a CPAP, a few days without power is not an option. As a licensed electrical contractor, we have wired portables and standbys across the Lewiston-Auburn region and out into the Kennebec County lakes country for more than two decades, and we pull every permit and inspection that comes with the work. Owners who already have a generator sitting in a shed and never finished the install are a regular call for us, too.
