Non-metallic.NM does not refer to the wire itself; the wire is copper. Nor does it refer to the jackets around the wires; those jackets are made of color-coded PVC (polyvinyl chloride)--black, white, and red.Instead, NM pertains to the sheathing--a 30 mil-thick PVC jacket--that binds the individual wires together.NM is used to refer to any type of electrical wiring sheathed in a plastic coating, not just Romex brand.
