Construction:

Conductor: Solid copper per ASTM B3
Insulation: All phases and neutral(s) are insulated with Polyvinyl Chloride (PVC) with Nylon Sheath
Ground: Solid soft drawn bare copper with kraft paper wrap
Binder: Kraft paper
Jacket: White 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.

*Ampacities based upon 2023 NEC Table 310.16 and do not take into account the overcurrent protection limitations in NEC 240.4(D) of 15 Amps for 14 AWG CU, 20 Amps for 12 AWG CU, and 30 Amps for 10 AWG CU (independent of the conductor temperature rating and stranding if size is present in table). Also, see NEC sections 310.15 and 110.14(C) for additional requirements.
*Ampacities have been adjusted for more than Three Current-Carrying Conductors.
