Southwire 10/2 Romex NM-B is a non-metallic sheathed cable for residential indoor wiring in normally dry locations. It is used for branch circuits that serve outlets, lighting and other residential loads. It may be fished through masonry or tile walls where it is not exposed or subject to excessive moisture or dampness.
Each conductor has color-coded PVC insulation with a nylon covering that meets the required thickness of Type THHN. A 30 mil color-coded PVC sheath covers the finished assembly. The cable is lead free and RoHS compliant.
The cable is rated at 600 volts. The conductors are rated at 90°C dry, but under NEC 2008 and NEC 2011 the ampacity is limited to 60°C. Its applications are outlined in NEC 2008 and NEC 2011 Article 334.
