Steve, what is the wattage of the emergency heat? As Tom stated you need to use the actual load not the circuit size. I also think the way you are doing the calcs is over inflating the numbers. Use volt-amps for all of you numbers then divide the final number by 240. Don’t forget to include the microwave, garbage disposal or dishwasher if they are going to be used. Provide some more information and we will help with the calcs.
