[RE-wrenches] 200A Automatic Transfer switch

[Kirk Herander]

The Kohler brand ATS will perform a contact closure when utility power fails for a two wire start generator. it doesn't switch over until it senses the generator ac is present.
Your Generac model may or may not be 2 wire start. The newer "smart" ones can be converted with a generac adapter kit.

Hi Wrenches.
Can anyone recommend a good 200A Nema3 auto transfer switch that does not need to have any generator feedback (ie. Generac version which requires signal from generator) to transfer. Basically looking for a dumb version which transfers based on loss of grid voltage, and then reconnects based on re supply of grid voltage.
The Gerearc version which was installed today relies on feedback from the generator which senses loss of grid voltage to authorize the transfer switch to toggle to back up mode. When the grid comes back the transfer switch switches back to normal mode without feedback from the generator voltage sense wires but not the other way around.

Thank you!
