Romex Wire and NM Electrical Cable

ROMEX Nonmetallic Building Cable: 12 AWG Wire Size, 2 with Bare CU Ground Conductors

Nonmetallic sheathed (NM-B) building cable is a flexible electrical cable consisting of three or more wire conductors (including one for grounding) bundled inside a thermoplastic jacket, or sheath, that is nonconductive and heat-resistant. It's lighter than armored building cable, making it easier to handle, and its pliable sheathing is easier to unspool and straighten out. It is commonly used in residential and commercial applications to provide power for outlets, lighting, and appliances.
