They are suitable for installation in motion picture studios, theaters, and places of assembly (100 people or more) per NEC 2008 and NEC 2011 Articles 230.43, 300.22(C), 330, 396, 518, 520, 530 and 645. These cables may be installed in approved raceways and as open runs of cable on a messenger. They may be installed exposed, concealed or in cable tray and may be run in spaces used for environmental air in accordance with NEC 2008 and NEC 2011 Article 300.22(C) ONLY.

Nexans MC 277 wire is LEAD FREE and RoHS compliant.

Construction

Conductor:
Solid soft bare, annealed copper per ASTM B3. Stranded soft bare annealed copper per ASTM B3 and ASTM B787 for sizes 14 to 8 AWG and ASTM B8 for sizes 6 AWG and larger.

Insulation:
Colored PVC/Nylon type THHN per UL 83, flame retardant, meeting UL VW-1 flame test.

Ground Wire:
Bare copper, sized in accordance with NEC 2008 and NEC 2011 and UL, with green THHN insulation.

Assembly:
Conductors are cabled with grounding wires. A marker tape/core protection tape combination assembles the core in an essentially round configuration.

Armor:
Interlocking aluminum tape armor applied directly over the core.

Bend Radius: 7 x overall diameter Notes: • Where stated, "nominal" and "approximate" values are provided for information purposes only and are subject to standard manufacturing tolerances. • Ampacities are in accordance with NEC 2008 and NEC 2011 Article 310.15 and 334.80, which are based on NEC 2008 Table 310.16 or NEC 2011 Table 310.15(B)(16) for conductors in a raceway or direct buried at 30°C ambient temperature. Ampacities for cables having more than three conductors have been derated per NEC 2008 Table 310.15(B)(2)(a) or NEC 2011 Table 310.15(B)(3)(a). • For correction factors for different ambient temperatures and ampacities at different conduct temperature ratings see NEC 2008 Table 310.16 or NEC 2011 Table 310.15(B)(16). • NEC 2008 and NEC 2011 Article 240.4(D) requires that over current protection not exceed 15 amperes for 14 AWG, 20 amperes for 12 AWG, and 30 amperes for 10 AWG copper conductors after any correction factors for ambient temperature and number of conductors have been applied. Exceptions to this may be covered in NEC 2008 and NEC 2011 Article 240.4(E) through (G). ¹Where the 4th conductor is the neutral of a balanced 3 phase system.
