Switching the neutral

Thank You Augie, for the reference. However, I was not specific enough in my question. I am looking more for general residential and commercial references, instead of industrial and plant applications.
 
What is it your looking for?

Basically you can switch the grounded conductor any time any place as long as you switch the ungrounded conductors of that circuit at the same time.
 
I am looking for references to show my new (green) helper, he asked why we can't switch the neutral in simple arrangements such as residential lighting. I explained to him the hazard it would present, I also want to show him what the code says about it.
 
Boy I really need some coffee. My first post I mentioned 200.7 which refers to identification of the grounded conductor, which is another rule I am going over with him. (He asked why we couldn't use the re identified white conductor for the return in a switch leg). I meant to say 404.2, which dspector has suggested.

I explain it like this:

The white switch-feed conductor that is spliced to the one or more blacks is a connection that should never need to be disturbed, whereas the white-conductor splice might be disturbed, say, during a fixture R&R.

If one were to find a fixture (or receptacle for that matter) with the wires/terminals connected to two white
wires in the ceiling/wall, it would be difficult to know which wire is the grounded and which is the hot.
