Thanks...........I've got a generator and auto transfer switch picked out.  Not too impressed with Generac for a livestock application.   What I need now is some sort of switch or breaker that I can put on certain circuits that I don't want to turn on/energize when the generator automatically starts.  When the power comes back on through the generator, I need certain circuits to remain "dead" so they don't overload the generator.   Similar to when the power goes out and your computer doesn't turn back on, you have to start it again.
