I think we are just having a discussion about the incongruities in the NEC. We have proved that you can find compelling language for either case, Since these are simply appliances that may not even be present when the decisions are made and the inspection performed, things like "nameplate" may not really mean anything. As a design choice, sharing these may not be a good idea since larger appliances may replace the cheapest thing the builder might choose to install but I am not sure there is really an unambiguous code case to be made. I bet I could get a fight started at the IAEI meeting tomorrow, with different jurisdictions having opposite opinions. The safest answer is always "what does the AHJ say?"
