Q: Hey Jim, I'm upgrading my service to a 400 amp. and while doing so would like to install a transfer switch. I'm looking at the Generac @ RTSD400A3, it seens to have some nice features and would fit nicely in the space available. The Generator would be installed later. Would this unit be compatible with all generator manufactures? I like Kolher generators would there be any issues? Thanks
by Randy Stubbs from Maryland on February 24, 2012

A: Unfortunately these products are proprietary so Generac only works with Generac and Kohler only works with Kohler. If you are planning on purchasing a Kohler generator you will need to purchase a Kohler switch.
