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.

M.T. Ruhl Electrical Contracting installed a Generac 20 kW standby generator in our home on the 11th of March, 2014. I found the company and its associates to be polite and professional. I dealt with Mark Ruhl directly, the president of the company. Mark was very helpful, gave us an extremely fair price, was attentive to my many questions, and helped facilitate a rapid installation to accommodate some unexpected personal needs of my own by providing sound insight into expediting permit processing by my township. The installation itself went very well; his associates were attentive and respectful, and provided a professional installation that included the home-link feature. They coordinated the plumber’s portion of the job perfectly and left our home clean and neat. Lastly, they reviewed all materials and instructions with me and answered all my questions. I would recommend M.T. Ruhl highly and already have referred three friends who are in the process of getting their generators installed by M.T. Ruhl as well. Blue Bell, PA
