I am finishing a basement and I want to install an outlet in a wall that has 2x2 framework against the concrete block foundation wall. The plan I have is to make a notch in the vertical studs to run the 12-2 romex cable through and use a steel plate over the notches. The rest of the cable will be secured against the block with fasteners screwed into the block. The cable will be at least 1-1/4" from the top or bottom plate and when it runs vertically down to the outlet box. Is this a valid interretation of the NEC section 300.4(D) where it states that all cable must be 1-1/4" from any surface of a framework member or it must have portection?
