Basically you figure out what loads you expect to have. If you have the equipment you get the wattage rating of each appliance and add them up. You figure 180 va per outlet. Lighting is 3 watts per square foot. Ranges are 40 amps for a calculation although a Jenn-air draws more. Dryers are 27Kw Range loads are calculated at 100% dryers 100% A/C the combined load of both blower motors and compressors -
Service minumum is 100 amp either way you look at it. 42 circuits max per panelbox.
