  2. Insulation:Polyvinyl Chloride (PVC)
  • Colors: Other Colors available; including Green with 2x15% +/- 5% Tolerance Yellow Extruded Stripe. Other stripes available.
  • Extruded stripes limited to sizes 4/0 AWG and smaller. 250 kcmil available in solid colors only.
  • Applications and Features:

    Southwire’s Machine Flex® power cables are suited for use in wet and dry areas, conduits, ducts, troughs, aerial supported by a messenger, and where superior electrical properties are desired. These cables are capable of operating continuously at the conductor temperature not in excess of 75°C for normal operation in wet and dry locations, 90°C for emergency overload, and 150°C for short circuit conditions. 1/0 AWG & larger rated for CT use.

    † 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.
