Southwire’s 600 Volt Type MC power cables are suited for use in wet and dry areas, conduits, ducts, troughs, trays, direct burial, 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 90°C for normal operation in wet and dry locations, 130°C for emergency overload, and 250°C for short circuit conditions. For uses in Class I, II, and III, Division 2 hazardous locations per NEC Article 501 and 502. Silicone Free.
Cond. Size | Cond. Strands | Diameter Over Conductor (in) (cm) | Inner Layer Thickness (mils) (mm) | Diameter Over Armor (in) (cm) | Outer Layer Thickness (mils) (mm) | Approx. OD (in) (cm) | Approx. Weight (lbs/1000') (kgs/km) | Max Pull Tension (lbs) (kg) | Min. Bend Radius (in) (cm) | |
