A house will have an electric range that has a nameplate rating of 14 kW. What is the load used to calculate the branch circuit rating?
What will be an ideal response?
Because this value is over 12 kW, column C of Table 220.55 cannot be used without a slight modification. The modification comes from Note 1 to Table 220.55, which says that for every kilowatt over 12 kW, the maximum demand for one range (8 kW) must be increased by 5%. Here is how this is done. The nameplate rating of 14 kW is 2 kW over 12 kW. At an increase of 5% of each kilowatt over 12 kW, the total percentage increase will be 10% (2 ? 5% = 10%). Increase the maximum demand for one range (8 kW) by 10% (8 kW ? 1.10 = 8800 W). So the actual value used for loading calculations for a 14-kW-rated range is 8.8 kW.
