I see some things in that chart that I wonder about, ex a central ac 24000btu is 3800/11400 run/additional starting watts. then a heat pump is 4700/4500. Why would a heat pump require fewer starting than run plus they do show capacity in btu for a comparison. Most heat pumps are central ac units so why such a big difference in starting watts? Lastly, most heat pumps have "emergency" heat strips that are also used in a defrost cycle, where basically when heating, it reverses the compressor, or the coolant routing to what is a cooling cycle and kicks the resistance heating coils in to provide heat to the outside unit to melt any frost that has formed.. I had a GE executive heat pump back about 40 years ago that would frost solid and even with the heat strips going would take quite a bit of time to defrost. I not have a Trane unit that is about 4 years old that rarely frosts up.
I know non of this really applies to his application. The best thing to do would be to look at the wattage/amperage ratings on the specification plate on each unit and add them up. For the most part it would probably be unusual if all were to start at the same time. If everything had been shut down it would probably be best to start the heavier draw appliances one at a time to prevent any sudden overload condition.
