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.

This 20 kW generator is not a do it yourself project, not even for an untrained electrician. I was extremely impressed with the work completed. The technician came with a full arrangement of tools and his work was as neat and orderly as you could expect. He took time to explain operational functions and things the home owner would like to know along the process as well as at the end of the installation. I am normally critical of companies that do work on my home/property but there was nothing negative to say about BOWCO Electric Inc. I fully recommend them! Nolan/Beckley, WV
