    The equivalent impedance of parallel feeds is lower than single feed. So fault current is more and so EGC to be big enough to carry the increased fault current without burning up.

    My thought also.

    Can't say I have ever run into it, maybe if you decided to never use larger than the minimum requirement of 1/0 for your parallel sets and were running a 4000 amp circuit
