PVC to support MC

[WCEI]

On a set of drawings we are working from, the engineer stated to install the MC in PVC. We assume for support?
If you only sleeve it through PVC without connecting the PVC on either in, is it legal? The MC will be properly connected with approved MC connectors.

IF permitted, and two or more MC cables are installed in the same PVC sleeve, without the ends sealed, is de-rating required?

Just as important as your answer, please let me know what Article you are referencing.

Thank you everyone.

Yes you can run MC cable in PVC sleeve. Derating is required where spacing between the cables is not maintained for more than 24". {310.15(C)(1)}
