This is 10/3 NM-B non-metallic sheathed cable for residential indoor wiring. It is used in normally dry installations as branch circuits for outlets, lighting and other residential loads. Its applications are outlined in NEC 2008 and NEC 2011 Article 334.
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 is applied over the completed assembly. Both the conductor insulation and the sheath are rated 90°C.
The cable is rated at 600 volts. Although the conductor is rated at 90°C dry, its ampacity is limited to 60°C under NEC 2008 and NEC 2011. It may be fished through masonry or tile walls where it is not exposed or subject to excessive moisture or dampness. It is lead free and RoHS compliant.
