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.
