If this is the case, why have a third in the first place? A couple of fans moving air around would be a whole lot less expensive. If you've a dark colored exterior, no shade, outside temps over 95 and don't want to add insulation to the windows, all three would probably need to be running to get your inside temps to below 80. Once they were all running, the current requirements can be handled by a 50 amp feed - but getting them running and not cycling would have to be done manually.
