Download PDF Download Excel Table

Construction:

Conductor:Solid per ASTM B3 or Combination unilay-stranded copper conductors per ASTM B787.
Insulation:All phases are insulated with Polyvinyl Chloride with Nylon Sheath
Jacket:Polyvinyl Chloride PVC jacket utilizing SIMpull® Technology.

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 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.
