Solid green, AC-Type, cable indicates HCF (Health Care Facility) rated cable. Type HCF cable has a green grounding conductor plus the armor/bond wire combination, thereby providing redundant or isolated grounding capability.
Type MC cable has only one equipment grounding means, a green grounding conductor.
"MCAP" cable is Southwire's trade name for type MCI-A cable. Constructed similar to MC Cable, an integral, bare grounding conductor in MCI-A is equivalent to a green copper ground. It stays in contact with the armor throughout the cable length to provide grounding.
