Two 12 kW electric ranges are in a two-unit dwelling. Using Table 220.55 Column C, what is the total demand?
a.16 kW
b.11 kW
c.8 kW
d.24 kW

Column C gives 11 kW for two ranges (not over 12 kW each). 8 kW is the value for one range, 16 kW doubles the single-range value, and 24 kW ignores demand entirely.
