c. Verify that the conductor ampacity at 75°C is sufficient for the calculated load to comply with terminal temperature requirements of 110.14(C): The 75°C aluminum column of Table 310.15(B)(16) ampacity equals 205 amperes, which is greater than the 175-ampere calculated load.

At this point there are two ways to find the appropriate conductor to supply the load per NEC 310.15(B)(3)(a): 1.) select a conductor of the same type, yet with higher ampacity rating, and calculate the adjusted ampacity of the conductor per NEC Table 310.15(B)(3)(a) until a sufficient conductor is selected, or 2.) apply the adjustment factor ...

NEC 2011 310.60 (C) (4) also provides an equation can for calculating the ampacity rating of the conductor based on the new ambient temperature, as an alternative (and more accurate) option: where. I’ is the ampacity corrected for ambient temperature. I is the ampacity shown in the tables. Tc is the temperature rating of conductor (°C)
