It isolates your house from the utility before the generator energises anything, so the generator can never back-feed the line a utility crew is working on. It is not optional and it is not a place to economise. The switch is sized to your electrical service , not to the generator. A 200A service takes a 200A switch whether the generator behind it is 13kW or 20kW. That is why we confirm your service size at the site survey before specifying one — ordering to the generator instead of the service is the most common and most expensive mistake on these jobs.

The switch is what makes the whole thing legal, safe and automatic. ### Why it becomes urgent It is sized to the electrical service rather than to the generator, which is the detail most competing quotes get wrong. ### Who buys it Every permanently installed standby generator, residential or commercial.
