Answer Posted / xyz
Short Circuit withstand capacity is to be checked for HT
cables. For LT breaker controlled motor feeders, the cable
impedance reduces short circuit current considerable, hence,
short circuit withstand capacity is not required to be
checked for the rated fault level of the LT motors.
