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 are insulated with Polyvinyl Chloride (PVC) with Nylon Sheath
  3. Jacket:Polyvinyl Chloride (PVC) jacket utilizing SIMpull® Technology.

Conductor Color Color Code:
  • 2/C: Black, White
  • 3/C: Black, White, Red

    • Jacket Color Color Code:
  • White: General Residential Wiring
  • Red: 2 Black and Red conductors - 208V-240V Circuits (no neutral)
  • Orange: No. 10 AWG General Residential Wiring
  • Yellow: No. 12 AWG General Residential Wiring
  • Blue: No. 14 AWG - 2 black and white conductors - 120V Arc Fault Circuit Interupter Applications

    • Applications and Features:

    Southwire's Romex® SIMpull® NMD90 cables may be used for both exposed work in dry locations or concealed work in dry or damp locations.
    The maximum allowable conductor temperature is 90°C. The minimum recommended installation temperature is -25°C for two-conductor cables and -10°C for three-conductor cables (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 Code for further information related to applications.

    * Ampacity values based on Canadian Electrical Code, Part 1 2024 Table 2 and do not take into account the overcurrent protection limitations in CEC Rule 14-104(2) of 15 A for 14 AWG Cu, 20 A for 12 AWG Cu, and 30 A for 10 AWG Cu (independent of the conductor temperature rating and stranding). See also CEC Rules 4-004 and 4-006 for additional requirements.
    * Inductive impedance is based on non-ferrous conduit with one diameter spacing center-to-center.
