Marco:

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 on-line article sums it up 
well:  http://ecmweb.com/nec/code-basics/electric_conductor_size_matters/

PS:  In my opinion, the neutral is a current carrying conductor in any 
system.  Disconnect it at your peril.

William
