OTEC series
OTEC 125A transfer switch
The OTEC series is a commercial-grade open-transition transfer switch, available in single and three phase and in both indoor Type 1 and outdoor NEMA 3R enclosures.
A transfer switch is what makes a standby generator legal and safe. 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.
Equipment only, 4 configurations. Installation quoted with your generator.
