A Generac generator can run on liquid propane, or tap right into your home's natural gas lines. It sits outside,just like you air conditioning unit. Form the generator, an external connection box attached to the outside wall of your home connects the generator to the automatic transfer switch, with emergency load center.
When utility power is interrupted, the transfer switch inmediately senses the problem and signals the generator to start. The transfer switch then safely closes off the utility line and simulatneously opens a new power line from the generator.
Within seconds, your generator begins supplying electricty to the critical emergency circuits have selected. If you system is operating on natural gas,it will continue to supply power for as long as the power is out. During this time he transfer switch continues to monitor the utility line conditions. This happens automatically no matter what the cause of the outage - whether it's a storm or just an equipment failure. And it happens whether you're home or away.
when the power returns, your generator goes back to sleep and waits until it's needed again.
