Explanation Formula Used: The expression to calculate the computed load is given by, Computed load = Demand max < 12 kW × ( 1 + Increase ) …… (I) Here, Demand max < 12 kW is the maximum demand for electric range rated not over 12 kW and Increase is the increase in demand by 5 % for each kW over 12 kW . Calculation: Refer to NEC Table 220.55 “Demand factors and Loads for Household Electric Ranges, Wall-Mounted Ovens, Counter-Mounted Cooking Units, and Other Household Cooking Appliances over 1 3 4 kW Rating”. For the range that are rated more than 12 kW but less than 27 kW , the maximum demand is increased by 5 percent for each additional kilowatt increase in rating by 12 kW . Calculate the increase. Increase = ( 15 kW − 12 kW ) 5 % = ( 3 kW ) 5 100 = 0
