I;ve seen Chase nipples put into the top of Mcc's (in wireways only) then several Tray cables run into them . I told the conmtractor I didn't feel this was a approved termintation method. I;ve seen Nipples from Mcc's up to the tray (lest them 24inches . But never Chase nipples?? My concern was even thought the nipples open into the wireways it leaves an unprotected opening.YER opinions Please.

I have seen what you describe. The wiring trough area of MCC's (for load conductors) does not provide direct access to any energized parts, I would be more concerned with securing the TC.

Take a look at 312.5(C) and 314.17(B).

In my opinion, between Articles 312 and 314, all electrical enclosures are covered.

The Scope sections 312.1 & 314.1 says otherwise.

I think that I can stretch the scope of 314 to cover just about any electrical enclosure including MCCs.

314 No way. 312 you'd have to use 90.4 and I really think you'd be streaching it. Which one is it a Cabinet(see definitions) Cut out box (No), Meter Socket encloser (No).
So then a MCC must be a Cabinet .
Cabinet (an encloser that is designed for either surface mounting or flush mounting and is provided with a frame ,mat, or trim in which a swinging door or doors are or can be hung. Doesn;t sound like a MCC does it??

The part of the MCC that you run the cables into is used as a pull box.

314.1 Scope
This article covers the installation and use of all boxes and conduit bodies used as outlet, device, junction, or pull boxes, depending on their use, and handhole enclosures.
