Home Stand-by Generators :: How They Work
Stand-by generators are completely automatic, helping to ensure that you remain safe from the negative
and potentially harmful effects of power loss.
- The system automatically and continuously monitors incoming power from the utility line.
- When utility power is interrupted, the control system in the generator automatically senses the loss of power and
signals the generator to start.
- The automatic transfer switch safely closes off the utility line and simultaneously opens a new power line from
the generator.
- Your generator supplies electricity to the critical circuits you previously chose to back up. Within seconds,
your home will regain electricity. Whether you're out of town, at the store, or watching the game on tv. There are
no buttons to push or switches to flip! The generator does all the work for you!
- When utility line voltage returns, the system transfers the electrical load back to the utility line. The
generator continues to run for an engine cool-down period of several minutes and the entire system stands ready for
the next power outage.
To ensure the system is always ready when you need it, your generator will run a 10-12 minute self-test cycle every week.
