Table 310.15 (B)(z)(a). Adjustment Factor for
More Than Three Current-Carrying Conduc-
tors in Raceway or Cable
Where the number of current-carrying
conductors in a raceway or cable
exceeds three, the allowable ampaci-
ties shall be reduced as shown in the
following table:
Where single conductors or multicon-
ductor cables are stacked or bundled
longer than 24 in. (610 mm) without
maintaining spacing and are not
installed in raceways, the allowable
ampacity of each conductor shall be
reduced as shown in the above table.
