I was wondering if anybody could explain why (per Chapter 9 Table 1 & 4) you are allowed a greater % of conduit fill for Over 2 Wires than you are allowed for 2 Wires.

Seems counter-intuitive, doesn't it?

I understand the concept of "jamming" explained in FPN No. 2, but as that is fro 3 conductors, I don't think it applies here.

Can anyone explain? I'd be interested to know.
