Stranded wire in Industrial against code

Is using stranded wire in Industrial work against code or just a standard? I know people use stranded and solid in Commercial work but almost never vice verse in Industrial its almost always stranded.

We always want to use stranded but it seems that lately engineers are specifying only solid. IMO #10 solid should not be permitted in a circular raceway.

I read you loud and clear. I'm adding a new paragraph to our standard specs:

"All raceways shall be rectangular." :)

I go out of my way to use stranded whenever possible.
When I engineer a job I specify no solid conductors
My supply house stocks lots of stranded MC now since I usually specify it.
I like to use 10/2 MC stranded for water heaters.

The only solid I've used in industrial was 4/0 for grounding grid and from grid to above slab metal (skids, motors, and such). Solid can be bent to follow contours and hold its shape.

I actually like solid.

For a short time the supply houses around here started stocking stranded MC, it did not go over well up here. It is now back to solid.

Trying to run stranded MC is like trying to push a car with a rope.

I have never seen solid wire that big. In fact can you even call it wire? Or do you just call it bar or round stock?
