“Thor Keck, Electrician for Haller Enterprise installed an interlock kit and circuit breaker for a back up generator for my home. The job entailed replacing some circuit breakers and moving a few other breakers to make room for the generator breaker; also adding the conduit/wiring to the generator inlet box. Thor was very professional and detailed oriented to make sure the job was completed correctly and in accordance with the NEC. I’m completely satisfied with his work, Thank You!”
