Code question using MC cable.

[upman]

I have a new 30x50 carport style metal building. Lots of challenges with the wiring etc. Trying to not have to do it all in conduit. Have metal boxes installed now. Have MC cable 12-2 and snap fittings. Question is can I run the cable between the metal siding and the steel studs? Or do I have to drill through every stud to run the cable. The aiding makes a perfect run for it. Ill try to post a pic.

MC cable is subject to the same NEC requirements as NM cable "Romex®", that it be protected from physical damage. Some define that zone up to 8 feet above the floor.

I would run down a stud to the box and back up the stud, across the top, then back down the next stud with a box. I would not go across the studs down low

I have done a couple going down from above and then to the next box. Using about 20ft of romex to go 6ft. Haha
It will have spray foam and drywall. Nothing exposed. Just wondering if it would be legal to run MC cable through that area from box to box. Obviously still anchoring near the box etc.

If the metal siding is as thick as a nail plate you would be OK. Otherwise not.
The Code make no distinction between plaster, drywall, wood, OSB, or metal when it comes to protection against physical damage.
