For a commercial office, is it acceptable to consider all receptacles as general purpose receptacles and apply the demand factor for 100% first 10 kVA and 50% for remaining? All receptacles would include receptacles for printers, faxes, and other specific plug in equipment. Even though a printer is a specific appliance and according to the NEC it wouldn't get a demand factor, how often is a printer actually used? 10% of the time?
When sizing feeders, it doesn't seem practical to size a feeder based on 100% of the load for these plug in appliances. That would mean they are running almost all the time.
Thoughts?
