Electrical Cable Current Carrying Capacity

Electrical Cable Current Carrying Capacity. Calculating the CurrentCarrying Capacity of a Cable The maximum allowable current carrying capacity (Iz) is obtained by multiplying the cable rated current "I0" by the total derating factor (Kt), as follows: Iz = Kt × I 0 (A) Light PVC-sheathed cables, flexible cables, metal-clad wiring cables in open or ventilated conduits (air).
