We have a couple of them at some of our offices, and disabled the functionality. They're great when working properly, but there's no telling when a motor might bind up and you suddenly find yourself back-feeding the generator (yeah, that was a weird call to make to my VP less than three months into opening that office when I was still very green... ahh, yeah, I hit the EPO button, but the thing is still running?). It's something to be aware of whether it's a traditional ATS (ala ASCO or Russelectric) or PLC-operated automatic breakers.
They are working on a project where this would do just that during power outages. They can sell power back to the utility at peak rates, this is an actual project with power company where they provide a generator to back up several homes all at once during outage.We have a couple of them at some of our offices, and disabled the functionality.

I worked on one at a Kohls distribution center that was similar, but theirs was for extra capacity for the utility. wasn’t a closed transistion, so when they transferred without notice, the conveyors would shut down, and would require restarting. I have seen only one closed transition switch, and they seemed to have problems with it never syncing, so it wouldn’t transfer. I think they had some software issues, but I left that site before they got it working.They are working on a project where this would do just that during power outages.
