Generic automatic transfer switch

[AC\DC]

I have a customer who wants to prep by switching from 200 to 4 and half and half one of 200 A on a automatic transfer switch
Easy said it done, but he doesn’t know what Generator he’s gonna get…
I’ve never done a Kohler generator. I’ve only done Generac.
And I figured you have to use their transfer switch but is there like a universal or the intermingle? Can I use a Generac transfer on a cooler or could I use a Kohler on Generac?
No, in Generac and how picky they are they would avoid any warranty if someone else transfer just wondering

You can use a Kohler RDT switch on any generator with 2-wire start capability. It is pretty affordable.

do you know if Generac would claim you know warranty issue for using someone else’s transfer switch? I just don’t like Generac.

I may be slow but what exactly does that mean?

I think from 200 amp to 400 amp with 2 200 amp panels and 1 of them being fed by a 200 amp ATS..

You can use a 2 wire start capable ATS, like a Kohler RDT (not RDX) as stated, or an Eaton or ABB if you’re into setting money on fire.

If you end up installing a Generac, you’ll have to get the 2-wire start kit for it.

I’m not aware of any warranty issues, and I think they would have a hard time justifying it, but I would reach out to the rep anyway.

Sorry I think it’s an RXT and RDT.

If it is a Generac residential switch, or Generac residential generator, it will not work. Everybody BUT Generac uses a two wire start (a slight exception is Onan, but they use a third wire to power the switch electronics with DC, the rest, the switch is powered off utility or generator, depending on what’s live)

Sorry, I use talk speaking and I don’t proofread cause I’m doing it while I’m driving. We’re going from a 200 amp to a 400 amp one of the 200 A will be a transfer switch.

Generac ATS would be difficult to make work, but a Generac generator with any 2 wire start ATS is pretty simple to make work. You just get the 2 wire start kit from Generac.

Yeah, they didn’t have the two wire start kits when I was installing them. It’s been a long time since I put in a Generac. The supply house that I was taking a continuing education class at today, started carrying Kohler. The rep said they offer a free install certification class now. I haven’t had any issues with the Cummins other than the last install, I’m waiting to see how well they service their warranty. I already know what’s wrong with it, but because I’m not an authorized dealer, I can’t do warranty work (at least get paid for it).

Generac were always 2 wire start compatible all the way back to the 90s or possibly 80s.

You had to do some minor mods but it was always there.

Not in any we installed. And that was probably in the 90’s The voltage sense for start was in the generator, not the transferswitch. The generator controlled the transferswitch, with everyone else, the transferswitch controlled the generator.

I've never been around a residential Generac install but I've done many commercial installs and startup since 1984 and I've never seen a Generac that wasn't 2 wire start.

Commercial yes, residential no. Each crew was doing on average two a day, and we had three crews. Did that for about a year. Generac had prefabricated whips with all the necessary wiring, and a built in loadcenter with a whip to the existing panel.
