...

Construction:

  1. Conductor: Bare copper per ASTM B3. Sizes #14 AWG - #10 AWG are solid. Sizes #8 AWG - #2 AWG are Class B compressed stranded per ASTM B8
  2. Insulation: All phases and neutral(s) are insulated with Polyvinyl Chloride (PVC) with Nylon Sheath
  3. Ground: Solid soft drawn bare copper with kraft paper wrap
  4. Binder: Kraft paper
  5. Jacket: Polyvinyl Chloride (PVC) jacket utilizing SIMpull® Technology

Applications and Features:

Southwire® Romex® Brand SIMpull® NM-B (nonmetallic-sheathed) cable may be used for both exposed and concealed work in dry locations at temperatures not to exceed 90°C (with ampacity limited to that for 60°C conductors) as specified in the 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.
