View detailsRA series
The RA series is the standard residential switch that pairs with air-cooled Cummins home standby units. Compact, aluminum NEMA 3R cabinet, wall-mounted next to the meter.
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.
Service-entrance rated versions include the main disconnect, so the switch can replace your existing main rather than sit beside it. That often simplifies the install and reduces what has to be reworked at the panel — but whether it is allowed depends on your meter configuration and your city.
Equipment only, 3 configurations. Installation quoted with your generator.
The RA 200A is sold by UTS ElectricPros, an authorized Cummins dealer in Dallas–Fort Worth. Buying through an authorized dealer is what keeps the manufacturer warranty valid — equipment bought from an unauthorized reseller frequently is not covered, and owners tend to find that out at the worst possible moment.

What it carries
A rule of thumb at 240V single phase, not a specification. The switch is sized to your electrical service rather than to the generator, so the real pairing is settled at the survey — but these are the sets a 200A switch is normally seen with.

View detailsWhat it is for
A generator with no transfer switch is a machine someone has to be at home to start, and connecting one without a switch backfeeds the utility line and endangers the crews working to restore it. The switch is what makes the whole thing legal, safe and automatic.
It is sized to the electrical service rather than to the generator, which is the detail most competing quotes get wrong.

The RA 200A is installed across the Dallas–Fort Worth Metroplex by our own licensed crews — the cities we serve, what installation involves, and a free on-site survey before any number is put in writing.

Installation is Dallas–Fort Worth only, carried out by our own licensed crews under TECL #40628 operating from Grand Prairie — because a generator is quoted against your gas meter, your panel and your city, which nobody can do from a warehouse.
