How Does a Home Backup Generator Work?

A Generac home backup generator senses a power outage, turns on automatically, and delivers backup power to your home. It will run until utility power returns - whether that's two hours or two weeks.

1 Utility Power Is Lost

Perhaps it's a storm. Maybe it's an equipment failure. In any case, the electricity you depend on is suddenly gone.

2 Your Generac Generator Senses A Problem

Within seconds, your generator prepares to restore your home's power.

3 The Generator Turns On Automatically - Whether You’re Home Or Away

Within a few seconds, it is up to speed and generating electricity.

4 Your Electricity Is Restored

The automatic transfer switch sends generator power to your home. And it will continue until utility power returns.

Mt. Salem Electric was great to deal with. From the first estimate to the final install they were with me every step of the way. Mt. Salem Electric was always responsive on all phone calls and emails. It was one stop for the documentation supplied to me for the permits, guidance of what to expect through the install process, arranging the plumber for my natural gas line and very courteous and professional with all correspondence. This was a lot of work on Mt. Salem’s part and everything was done with care and cleaned up when their electricians left. They came to my home to test the generator and give me some instructions and said they will be back is 4 weeks to make sure all is ok. GREAT job!! Rich – Pittstown, NJ
