Its great you call it a grounded condutor and not a neutral... and per the NEC!
When its a current carrying conductor, or due to harmonics.
For example in wiring for computer branch circuits, for a full boat, a neutral is pulled for each hot conductor, due to harmonics. In this case, its not a neutral, but a grounded conductor. For a three phase 120/208 system, you will have 6 current carrying conductors.
But the same full boat, for incandescent track lighting, the neutral is not a current carrying conductor and it is a neutral.

Heres 310.15 C from the 2002 NEC
(4) Neutral Conductor.
(a) A neutral conductor that carries only the unbalanced current from other conductors of the same circuit shall not be required to be counted when applying the provisions of 310.15(B)(2)(a).
(b) In a 3-wire circuit consisting of two phase wires and the neutral of a 4-wire, 3-phase, wye-connected system, a common conductor carries approximately the same current as the line-to-neutral load currents of the other conductors and shall be counted when applying the provisions of 310.15(B)(2)(a).
(c) On a 4-wire, 3-phase wye circuit where the major portion of the load consists of nonlinear loads, harmonic currents are present in the neutral conductor; the neutral shall therefore be considered a current-carrying conductor.

You lost me. If you have one grounded conductor for each phase conductor they all count as CCC's regardless of the load. Is this what you meant?
 
Tom Baker,

"For example in wiring for computer branch circuits, for a full boat, a neutral is pulled for each hot conductor, due to harmonics. In this case, its not a neutral, but a grounded conductor."

I have always heard it referred to as a "Net Work" until recently. We were being subcontracted by a company from Oklahoma. The Forman asked me to set up a full boat. I had no clue what he was talking about. He thought I was being a wise guy and we both had a good laugh when it was cleared up.
I am curious if anyone else has a term they use that would sound foreign to other parts of the country.

Don't get out much, Trevor?

I picked those terms up from the guys back at the hall. What do you call it when you have all three phases and a neutral?


Three phase and a neutral.

Reminds me of a true story from some years back:

One of my best friends, his brother, and I were watching a movie on TV. There was a reference to "head cheese", and my friend started laughing, which puzzled his brother, which in turn puzzled my friend.

You see, the brother had only heard of the real cheese by that name, while my friend had only heard of the other definition. I got the best laugh of all while explaining to both of them each other's known definition.
 
Full boat,something you get in a poker game
Full house, when my inlaws come over
Family,what we all deal with daily
Network,NBC,ABC,FOX,CBS
