True.

However, consider the entire reason the conductor is larger than it needs to be (for ampacity alone) in the first place. Considering identical sources, which do you think has greater fault current at the load end? A small conductor on a short length circuit? Or a large conductor on a long length circuit? Suppose they are both selected to have the same percentage voltage drop, and therefore would have the same total conductor resistance. Would you expect fault current to be less, greater, or equal on the larger/longer circuit?

How did you make such a basic question so complicated?

You keep changing the perimeters of Toms statement.
