What is the voltage? Look at Table 220.55 column C.
1 Range would have a maximum demand of 8 kw + a 5% increase for every additional KW or major fraction there of more than 12.
Additional KW = 16.75 kw - 12 kw = 4.75 (round up)
Increase = 5% per kw x 5 kw = 25%
8 kw x 25% = 2 kw
Total load = 8 kw + 2 kw = 10 kw
I=P/E
I=10000/240=41.6 amps
