In the exhibit, the designer expects the total connected load to equal the sum of the 4 motor loads:

4 motors 1000 VA each = 4000 VA expected

However, Revit is showing a Total Connected Load of 3606 VA instead.

This difference occurs because Revit applies Motor Demand Factors automatically when a load classification is set to ''Motor.'' Demand factors modify the total connected load based on electrical engineering rules.

Revit documentation confirms:

''Assign demand factors to load classifications.''

''Demand loads can be shown on panel schedules.''

In the exhibit, the Load Classification shows Motor with a Demand Factor of 117.87%, which modifies the connected load values in the switchboard totals.

Revit is therefore calculating the effective connected load based on the applied demand factor, not a simple arithmetic sum. That is why the panel's connected load number 4000 VA.
