I have always heard that you use 75 degree table for MC but after looking into it further I cant find much that would back that up.
Under 330.80 the NEC redirects you to 310.14 or 311.6 which didn't give much of an answer either. I was mostly interested once I started looking into cost differences for running MC to RTU's in commercial settings.
Also
What is your code interpretation for how many #12 MC cables can be bundled together before you have to derate? I say 10 but would like to hear what others have to say
