(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 NFPA70These values can be taken as a reference for submerged cable or in contact with water in wells of up to 100 meters deep. For wells deeper than 100 meters, each case must be analyzed in terms of how the cable will be affected by the environment due to temperature ratings, liquids and other conditions which may lower the cable conductivity.
