Generator FAQ
A permanently installed Generac home backup generator protects your home automatically. It runs on natural gas or liquid propane (LP) fuel, and sits outside just like a central air conditioning unit. A home backup generator delivers power directly to your home’s electrical system, backing up your entire home or just the most essential items.
When a Generac home backup generator senses a power outage, it 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.
During a utility power outage, an automatic backup generator provides numerous advantages over a portable generator:
- The American Red Cross recommends permanently installed backup generators as a safer way to provide backup power to a home than a portable generator.
- With an automatic backup generator properly installed outside, your home is protected from deadly carbon monoxide poisoning that is a much greater risk with portable generators.
- Running on the home’s natural gas or LP fuel supply, it is less expensive to run than gasoline and sources such as natural gas do not need to be refilled.
- They start automatically within seconds of a power outage, and eliminate the need to haul a portable generator outside or run extension cords throughout your home.
- They provide protection 24/7, whether you’re home or away, and they turn themselves off when utility power returns, so there is no need to monitor the unit during an outage.
As an option, Generac offers the Guardian Series systems prepackaged and pre-wired with comprehensive installation instructions. You could perform the simpler site preparation steps and have a professional make the electrical panel and fuel connections, or you could complete the entire installation yourself. However, for safety reasons and to ensure adherence to all local, state and national electrical codes, particularly for non pre-wired or larger systems, Generac recommends you use an authorized Generac dealer or licensed contractor. When selecting a site, always follow the guidelines in the Site Selection and Preparation section of your unit’s installation manual.
