Just wondering if this can be used with Kohler or Generac generators, or if it's specific to the Cummins brand?

This transfer switch is designed for use with specific Cummins generators. Installing this with any other generator would void the manufacturer warranty. To view the specific generator models, please see page 5 of the product manual found on this item's specifications page.
