Can I use the 240volt twist lock plug from the gen to a cutoff hydro box, then hook up a 240 well pump, a 120 wood furnance fan and a 120 plug in that is wired from a sub panel box that is hooked up to the cut off box, the well pump would only come on when the water went down 5 gallons and the fan would come on when the temp dropped 2 degrees F the plugin wold be the one on all the time drawing about 5amps
