Which voltages are considered for general use receptacle calculations?

Explanation:
General-use receptacle calculations are based on the nominal feeder voltage because the feeder is what supplies all the receptacle circuits and carries the total load. The receptacle loads are added up to determine how much current the feeder must deliver, and the VA per receptacle is referenced to the voltage level of the feeder. Using the feeder voltage ensures a consistent, correct estimate of the feeder’s current-carrying capacity. If branch-circuit voltages were used instead, it would mix different voltages and could mis-size the feeder. So, the voltage considered is the nominal feeder voltage.
