Transfer switches

Don't take chances with electric generators

Used improperly, electric generators — even small, portable models — can threaten your safety and the safety of everyone around you, including our employees working on the electrical system.

Portable generators are not designed to be connected to your house or any building wiring. Doing so can feed power back onto our electric lines. This is life-threatening for utility crews working to restore an outage and curious children seeing a power line on the ground. Improper installations also can do serious damage to the generator itself, as well as equipment and appliances you use with it.

Install a transfer switch

The only safe way to connect a generator to your existing wiring is to have a licensed electrician install a transfer switch. A transfer switch isolates your circuits from our system and prevents dangerous backfeed. The transfer switch transfers power from the utility line to the power coming in from the generator. The electricity from your generator takes a safe path directly to the circuits in your home.

Transfer switches are convenient. They allow you to operate appliances you typically could not power with a portable generator, including furnaces and well pumps. And you don’t need extension cords.
