Southwire HCF MC AP type MC cable is constructed with solid soft drawn copper type THHN circuit conductors (rated 90 deg C dry), redundant grounding provided by an armor assembly comprised of interlocked armor with an aluminum grounding/ bonding conductor, a green insulated copper grounding conductor. The insulated circuit and grounding conductors are cabled together and wrapped with a binder tape bearing the print legend. The bare aluminum grounding/bonding conductor is located outside the binding tape covering and has the same lay as the insulated conductors. Green aluminum interlocked armor is snugly wrapped around the conductor assembly. To insure proper cable termination, refer to the installation instructions provided with every reel and coil.
