This is 10-3 with ground NM-B non-metallic sheathed cable in an orange jacket, equivalent to Romex NM-B. It is used in normally dry residential installations as branch circuit wiring for outlets, lighting and other residential loads. Its applications are outlined in NEC 2008 and NEC 2011 Article 334.
It has three 10 AWG conductors plus a 10 AWG bare copper ground. Each conductor has color-coded PVC insulation with a nylon covering, and a 30 mil color-coded PVC sheath covers the assembly. The cable can be fished through masonry or tile walls where it is not exposed or subject to excessive moisture or dampness.
The cable is rated at 600 volts and a 90°C conductor temperature when dry. Under NEC 2008 and NEC 2011, its ampacity is limited to the 60°C column. It is lead free and RoHS compliant.
