This cable has an uninsulated ground wire that touches the protective metal armor so it can be used for bonding and grounding. It's often used along the exterior of walls to carry power to outlet boxes. Also known as AC and BX cable.

A braided bronze armor provides excellent protection against abrasion and other damage. The wires are tin-plated for corrosion resistance, and the insulation resists corrosive chemicals and salt water.

Attach conduit and armored cable to a knockout in an outlet box or enclosure.
