Hi horsegoer, you made me break out the ole code book, and according to 2008NEC, 330.30(D)(1), Type MC cable shall be permitted to be unsupported where the cable; (1) Is fished between access points through concealed spaces in finished buildings or structures, and supporting is impractical;Yes. But how would you support the vertical MC in a block wall? THanks.
I beleive the MC has to be rated for it. Running it down block walls is fine. No need for support. Same concept as of you were to do a cut in box and run it down dry wall.I was told that conduits can be run vertical in a bloch wall through the block openings. Can MC be run this way although I guess supporting it would be an issue?
