Marco,
Seems to me he's right. It carries the net current difference between
L1 and L2 from the transformer to the loads.
But not having any EE training, I'm willing to learn better.

Marco,
When you are drawing 120 VAC, the neutral is a current carrying conductor.

You have opened a can of worms. I hope you are happy!
Are you looking for the legal definition or to discover if the neutral
conductor actually carries current? The answer to the legal definition is
in 310.15(B)4 (2002), and the answer is: It depends (on the type of
service). This
Thanks for sending that link, William.
OK.let's try it from a different perspective.
When you're running, say, three three-phase hot conductors from point A to
point B with a neutral conductor, should that neutral be considered current
carrying from the perspective of more than three
Marco,
Take a look at 2008 NEC 310.15(4)(a). The neutral conductor isn't
counted for the purpose of NEC 310.15(B)(2)(a) when it is part of a
circuit where it only carries the unbalanced current.

Will non-linear loads be expected? If so, the neutral is considered to be
a current carrying conductor and needs to be counted. If no non-linear
loads, then the neutral is not counted.
Code citation below (2008):
310.15(4) Neutral Conductor.
(c) On a 4-wire, 3-phase wye circuit
How about some clear definitions-for-dummies of 1) linear loads and 2)
non-linear loads?
