SPEC 22053
NMWU Copper
Copper Conductors, 300V / -40ºC MIN, 60ºC MAX, PVC / Nylon Insulation, PVC Jacket
Construction:
- Conductor:Solid per ASTM B3 or Combination unilay-stranded copper conductors per ASTM B787.
- Insulation:All phases are insulated with heat-resistant thermoplastic polyvinyl chloride (PVC) insulation and nylon sheath
- Jacket:Polyvinyl Chloride PVC jacket, sunlight, moisture, and fungus-resistant
Applications and Features:
Southwire's CSA-NWMU cables may be used for underground installations, including direct burial. It may also be used for environments exposed to the weather in dry and wet locations. The maximum allowable conductor temperature is 60°C. The minimum recommended installation temperature is -40°C for two-conductor cables (sizes AWG 14 to AWG 6) and -25°C for all other sizes. For three-conductor cables the minimum recommended installation temperature is -10°C (with suitable handling procedures). Material should be properly stored above 0°C for 24 hours prior to installation. The maximum voltage rating for all intended applications is 300 volts. Consult the Canadian Electrical Code1 for further information related to applications.

† 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.
* Inductive impedance is based on non-ferrous conduit with one diameter spacing center-to-center.
