Cables listed and marked as CMX are used in_____.

Explanation:
CMX marks a nonmetallic-sheathed cable that is intended for general use inside buildings, specifically in residential-type installations. It is suitable for wiring runs inside walls, ceilings, and similar indoor spaces in homes, where the cabling is not exposed to outdoor weather or hazardous conditions. Because of that, CMX is the choice for residential dwellings. Cables used for outdoor lighting, hazardous locations, or industrial facilities require different listings that are rated for those harsher or outdoor environments, so they wouldn’t carry the CMX designation.
