Re: Grounded conductor as current carrying conductor
Do you mean "grounded," as in what is commonly called "neutral"? If so, then that conductor carries current all the time.
Do you mean "grounding," or more properly "equipment grounding conductor," or what is commonly called "ground (green or bare copper) wire"? If so, look at 250.6 and 250.24(A)(5). I am sure there are other, and perhaps more relevant, code articles. But I have to run to a meeting, and can't look them up now.

Re: Grounded conductor as current carrying conductor
If you are talking about an installation where you have and existing conductor in conduit that was a ground and now you would like use as a hot? You should be allowed to do this as long as you mark appropriately on the conductor that it is no longer a ground (lots of marking tape). I know I'm going to get flamed for this, its not the best senario but sometimes its acceptable.
Also, if you are going to use the conduit as the equipment grounding conductor, then make sure all the connections have been properly made including bonding jumpers, incase the previous installer decided because there used to be an equipment ground, he didn't have to do a good job grounding the conduit.
