Specification

Building Wire
APPLICATIONS
For use primarily in residential wiring, including branch circuits for outlets, switches,
etc. May be installed in both exposed and concealed work in normally dry locations.
May be installed in air voids of masonry block or tile walls where these walls are not
subject to excessive moisture or dampness. May be installed in locations with
temperatures up to 90°C, but with the ampacity limited to that of 60°C conductors.
Added Circuit: For use primarily in residential wiring for branch circuits supplying
outlets located in bedrooms and other areas. Has two separate neutrals so one cable
can be used to run two circuits when sharing of a neutral is not allowed.
CONDUCTORS
Solid conductors: Soft, uncoated copper per ASTM-B3
Stranded conductors: Uncoated copper per ASTM-B3 and ASTM B8
CONDUCTOR INSULATION AND JACKET
Color-coded PVC (polyvinyl chloride), rated 90°C dry with clear nylon (polyamide).
Added Circuit: Color-coded PVC rated 90°C: black, white, red and white with red
stripe. Insulated conductors also jacketed with clear nylon (polyamide).
GROUNDING CONDUCTOR
Soft, uncoated copper per ASTM-B3
ASSEMBLY
Two-conductor constructions have the insulated conductors laid parallel. Ground
wire is wrapped with paper and laid parallel between the insulated conductors. The
entire construction is wrapped with a paper separator before applying the jacket.
Three-conductor constructions have the insulated conductors twisted together or laid
parallel to each other. Ground wire is wrapped with paper and twisted together or laid
parallel to the insulated conductor.
JACKET
30 mil-thick PVC (polyvinyl chloride) jacket applied over the complete assembly
14-2, 14-2-2 & 14-3 w/ground: white
12-2, 12-2-2 & 12-3 w/ground: yellow
10-2 & 10-3 w/ground: orange
8 AWG or larger: black
