NM-B 600V Copper Indoor Building Wire

NM-B 600V Copper Indoor Building Wire

Application
Type NM-B (nonmetallic-sheathed cable) may be used for both exposed and concealed work in normally dry locations at temperatures not to exceed 90°C (with ampacity limited to that for 60°C conductors) as specified in the 2011 National Electrical Code. NM-B cable is primarily used in residential wiring as branch circuits for outlets, switches, and other loads. NM-B cable may be run in air voids of masonry block or tile walls where such walls are not wet or damp locations. Voltage rating for NM-B cable is 600 volts.
Standards:
Type NM-B cable complies with:
• ASTM B-3 and B-8
• UL Standard 83
• UL Standard 719
• Federal Specification A-A-59544
• National Electrical Code, NFPA 70. 2011 Edition
• RoHS/ REACH

construction
Type NM-B cable is manufactured as 2, 3, or 4 conductor cable, with a bare ground wire. Copper conductors are annealed (soft) copper. Stranded conductors are compressed stranded. Conductor insulation is 90°C-rated polyvinyl chloride (PVC), nylon jacketed. Type NM-B is designed for Easier Pulling, Resulting in Easier installation. The cable jacket is color-coded for quick size identification; White - 14 AWG, Yellow - 12 AWG, Orange - 10 AWG, and Black - 8 AWG and 6 AWG.
