Other structures permitted to be Types III, IV, and V construction. Cables shall be concealed in within walls floors, or ceilings that provide a thermal barrier of material that has at least a 15 minute finish rating as identified in listings of fir rated assemblies.
When I look at this for these types of structures. I see that nm/nmc/nms would not be allowed in an accessible attic, an accessible crawl space or any wall that does not have a 15 min fire rating on both sides including exterior walls. Would this be the correct enforcement of this code section.
