(1) Three single-conductor cables displayed in flat, in contact with each other. (2) Three single-conductor cables displayed in flat, separated by 1 diameter between each other. (3) Three single-conductor cables displayed in a trefoil in contact with each other. (4) Calculation of Inductive reactance valid for two-conductor, three-conductor and five-conductor cables. (5) Calculation of Inductive reactance valid for four-conductor cables. (6) 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.
