NMWU Copper
Copper Conductors, 300V / -40ºC MIN, 60ºC MAX, PVC / Nylon Insulation, PVC Jacket
Application
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.

Standards & References
CSA-NWMU cables meet or exceed the following requirements:
- ASTM
- CSA C22.2 No. 48 (non-metallic sheathed cable)
- Canadian Electrical Code1
- CSA FT1 Flame Test Rating
Construction
Southwire's CSA-NWMU cables are available as two or three-conductor cables with a bare grounding conductor. It is manufactured using annealed (soft) copper conductors with compressed standing for stranded conductors; a heatresistant thermoplastic polyvinyl chloride (PVC) insulation and nylon jacket for the phase conductors with a sunlight-" moisture-" and fungus-resistant PVC jacket for the overall construction.
- Ground Conductor
- Copper Conductor
- PVC / Nylon Insulation
- Black PVC Jacket• Conductors are white and black (for 2 conductor cables).
- Conductors are white" black and red (for 3 conductor cables).
