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.

Mark’s company exceeded my expectations of cost, quality, and customer service. After meeting with six companies that installed whole house generators from different manufacturers as well as Generac, I was convinced that Moriarty Electric Co. was the one to go with. The owner Mark was extremely knowledgeable about all aspects of power generation and electrical distribution systems. He made several additional visits to my home to answer my questions and provided me recommendations for my project that other companies had not addressed. Mark was extremely personable, patient and very detailed as we went over the project a number of times. Mark provided me a quote with wording “Cost not to exceed” and we actually came in under budget! In my research to select a generator and installer I discovered there are a lot of dealers that sell Generac generators, however not everyone goes the extra distance to have their staff trained for comprehensive servicing. Moriarty Electric Co is a “Certified Generac Service Dealer” and their technicians are trained and recertified by Generac to provide diagnostics, maintenance, and repair of Generac generators. Moriarty Electric Co. is further recognized by Generac as an “Elite dealer” who provides superior levels of sales and service. During the installation Mark noticed several National Electrical Code violations by work previously performed by others and made recommendations to bring them up to code at no additional charge. His technicians were always on time, extremely polite, experienced and kept the job site clean. Whenever I called his office Mark’s office manager Karen helped me resolve any questions that I had. There were no surprises and all work was performed in a timely manner. Overall the company exceeded my expectations of cost, quality and customer service. I would highly recommend Mark and his team to provide their services for any electrical project! Bill in York, ME
