for arc flash analysis(3 phases), i upload as arcing short circuit current,
this formula is just for 3 phase or can we use that for single phase equipment as well? if it is applicable then, we need to use single phase current instead of 3 phase current, right? and for system voltage, we need to use phase to ground voltage, right? how about the conductor gap for single phase equipment? and how about the distance factor(D) and distance exponent (x) for single phase equipment?
