Re: MC cable in masonary block
Is the brick to be filled? If so then.
30.12 Uses Not Permitted.
Type MC cable shall not be used where exposed to the following destructive corrosive conditions, unless the metallic sheath is suitable for the conditions or is protected by material suitable for the conditions:
(1) Direct burial in the earth
(2) In concrete

Pick up on the words "unless the metallic sheath is suitable for the conditions"
Then consult w/ manufacture of the mc that you plan to use.
