(1) Current-carrying capacity of cables with up to three conductors, installed in ducts or directly buried, up to an ambient temperature of 30ºC, according to chart 310.15 (B)(16) of the NFPA 70. As from four-conductors, we’ve additionally applied the correction factor for more than three conductors from the chart 310.15 (B)(3)(a) of the NFPA70.
