Note: The reactance of disconnecting switches for low-voltage circuits (600V and below) is in the order of magnitude of 0.00008 - 0.00005 ohm/pole at 60 Hz for switches rated 400 -4000 A, respectiVely.

Note: Increased resistance of conductors in magnetic raceway is due to the effect of hysteresis losses. The increased resistance of conductors in metal non~magnetic raceway is due to the effect of eddy current losses. The effect is essentially equal for steel and aluminum raceway. Resistance values are acceptable for 600 volt, 5KV and 15 KV insulated Conductors.

Size AWGor

These are only representative figures. Reactance is affected by cable insulation type, shielding, conductor outside diameter, conductor spacing in 3 conductor cable, etc. In commercial buildings meduim voltage impedances normally do not affect the short circuit calculations significantly.
