Your generator will keep running as long as it has a fuel supply. If connected to natural gas, it can operate indefinitely. If using propane, runtime depends on your tank size—typically several days before needing a refill.

Portable Generators: Require manual setup and fuel refills, and can only power select appliances using extension cords.

Whole-Home Generators: Turn on automatically, connect to your home’s electrical system, and run on a continuous fuel supply—providing seamless backup power.

Automatic standby generators are essentially backup generators. In the event that your main generator fails, the automatic standby will kick in and restore power. Automatic standby generators will operate whether you are home or are away, and run on natural or liquid propane gas. Within seconds of an outage, the standby generator will automatically supply power directly to your home’s electrical circuit breaker box. After utility power returns, the standby generator will then automatically shut itself back off until the next outage. If you are thinking about installing an automatic standby generator, call Bonfe Plumbing, Heating, Cooling, Electrical, & Sewer to assess your home and provide you with more information and even a free price estimate.
