Applications 
Type MC Cable is primarily used for services, feeders, and branch circuits as specified in the 2011 National Electric Code. Type MC cable with Type XHHW-2 conductors may be used in wet or dry locations at temperatures not to exceed 90°C.  Used for power and lighting indoors, exposed or concealed, in cable tray where identified for such use; in a raceway, or in dry locations and embedded in plaster or against other masonry.  Voltage rating for XHHW-2 conductors is 600V.

Construction
Compact stranded AA-8000 series aluminum conductor material per ASTM B800, ASTM B801, ASTM B836, ASTM B901 (Single Input Wire), as applicable.  XLPE insulated XHHW-2 conductors are twisted with a bare conductor.  A binder tape is wrapped over the conductors with interlocked aluminum tape applied over the assembly. Rated 90°C wet or dry and is flame and sunlight resistant.

Specifications
Type MC cable with Type XHHW-2 conductors are manufactured and tested in accordance with the latest revisions of:

  • UL 44 for Thermoset-Insulated Wires and Cables
  • UL 83 for Thermoplastic-Insulated Wires and Cables
  • UL 1479 Standard for Fire Tests of Through-Penetration Firestops.
  • UL Classified 1, 2, and 3 Hour Through-Penetration Firestop Systems.
  • UL 1569 for Metal-Clad Cables.
  • IEEE 1202 - Flame Testing of Cables for Use in Cable Tray, in Industrial and Commercial Occupancies (70,000 BTU/hr).
  • ICEA T-29-520 - Vertical Cable Tray Flame Tests (210,000 Btu/hr).
  • ICEA S-66-524 and requirements of the National Electric Code
  • ICEA S-95-658 (NEMA WC 70) construction requirements
  • Federal Specification J-C-30B

Color Code

For Special Order

  • The entire assembly can be covered with a PVC or CPE outer jacket (black or color).  Jacketed MC Cable may be used in wet locations, either direct burial, in underground conduit, or overhead. 
  • Halogen free jackets are available upon request
  • A black jacket (on individual conductors) with color stripes can be requested.
  • Bare Ground conductor available upon request.
  • For sizes not listed above please contact sales.

Ampacity
To determine correct ampacity by conductor size, please consult the National Electric Code, latest edition.
