I have never seen a generator that syncs to the utility for live, no break transfer. I'm sure such a thing exists, but that sounds crazy dangerous to me. Generators sync to each other, not the utility.
Most of these come in open, delayed, or closed transition models: http://www.gedigitalenergy.com/powerquality/ATSHome.htm For open and closed transitions you'll most certainly want to sync to utility to transition between the two. For the delayed transition model it'll stop at the intermediate "open" point for a configurable amount of time during which the load is disconnected from everything (i.e. let all the motors spin down first). ~Seth
