I have a 84 Pole Panel (120/208V/3P/) with 74 Outlets and 10 Lighting circuits all on 20 AMP breaker each.

What is the best way to calculate the existing load for the office

Should I use Table 220.44 (Demand Factors for Non-Dwelling Receptacle Loads), but I'm confused on how much load I should show on each circuit since it states "These demand factor do not apply to receptacle load calculated based on 220.14(K)(1).


I assume lighting will be at 100% based on Table 220.42 (Lighting Load Demand Factor), since I don't see a a separate category for Office.


Or is my best option is to use Table 220.102 (Method for calculating Farm Loads for other than Dwelling Unit)
