What is metal-clad cable?
Metal-clad cable comes in several varieties, but the type you’ll find at most home centers is three insulated wires (two circuit conductors and a green equipment grounding conductor) protected by a flexible armor usually made from aluminum. MC cable is identified by the gauge of the wire, not the diameter of the armor. The most common sizes are 14 gauge, 12 gauge and 10 gauge.
