Generator to Generator Transfer Switch
We have used the Cummins OTEC ATS but they are getting hard to find parts for and the programming is proprietary from Cummins. This is for a business/gov and no I can't use bootleg software.
We are looking at moving towards a COTS ATS, especially at our locations that don't have commercial power. We have 3 locations that are generator only. We are installing 22kw 240 single phase generators, but generally the ATS we have been buying have have been 200 amp rated.
We don't want/need isolation bypass. ASCO seems to only offer a gen to gen ATS in the 7000 series which is expensive. I can't decipher the ABB Zenith or the Siemens Russelectric ATS product manuals to to identify if something is offered.
Any ideas?
