(1) Ampacities are in accordance with Table 310.16 of the NEC for conductors in raceway or direct buried at 30°C ambient temperature and 90°C
conductor temperature, where the 4th conductor is the neutral of a balanced 3 phase system. If the 4th conductor is to be used as a current
carrying conductor, then a derating factor of 80% is to be applied to the ampacity of all 4 conductors, as per Article 310.15(B)(2)(a) of the NEC.
For correction factors for different ambient temperatures and ampacities at different conductor temperatures, see Table 310.16 of the NEC.
