This is 6-gauge, two-conductor non-metallic sheathed cable with a bare ground, the heavy-duty end of the Romex-style NM-B line. The copper conductors are insulated with PVC plus a nylon jacket rated 90°C dry, and the whole assembly is rated 600 volts, though code limits ampacity to the 60°C column. It suits dry, indoor residential runs for high-draw circuits such as ranges, subpanels and large appliances. Against 12/2 and 10/2 NM-B, it carries far more current but is stiffer and harder to bend, so it is reserved for the circuits that need it.

This is 6/2 Type NM-B non-metallic sheathed cable with ground, 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.
The conductors are stranded annealed soft bare copper. Each is insulated with color-coded PVC and a nylon covering that meets the thickness required for Type THHN. A 30 mil color-coded PVC sheath, rated 90°C, covers the completed assembly. The ground is soft bare copper.
The cable is rated at 600 volts. Its conductor temperature rating is 90°C dry, but 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.
