Specification

14/3 W/GRND Solid NM-B Round Copper Cable 600V

Application:

600 Volt, multi conductor cable constructed with copper conductors, thermoplastic insulation (PVC/Nylon) rated 90°C with a bare copper ground, enclosed within an overall polyvinyl chloride jacket. The allowable ampacity is limited to 60°C per the NEC. Type NM-B Cables are primarily used in dry locations for residential wiring as branch circuits for outlets, switches and other loads. Type NM-B Cables are permitted for both exposed and concealed work in normally dry locations except as prohibited by NEC and also permitted to be installed or fished in air voids in masonry block or tile walls where locations are not damp or wet. Voltage for all applications is 600 volts.

Construction:
Conductor: 

Fully annealed bare copper. Solid conductor per ASTM B3.

Insulation:

Extruded flame retardant, heat and moisture resistant colored Polyvinyl Chloride (PVC) compound. 

Overall Jacket:

Extruded tough Polyamide (nylon) compound. 

Ground:

Bare uncoated solid copper wrapped with a fire-retardant paper tape. 

Assembly:

Flat configuration: Paper wrapped ground Placed between the insulated conductors and laid parallel.
Round configuration: Insulated conductors and ground twisted together. 

Separator:

A suitable paper wrap applied over the assembled conductors.
