Description

MC Cable with THHN Ground | Lightweight Aluminum Armor | 600V THHN/THWN Conductors-Picture1

Product Overview

MC Cable with THHN Ground is a high-performance, cost-effective armored cable designed for power distribution and control circuits in commercial, industrial, and multi-residential settings. Featuring lightweight aluminum interlocked armor and UL-listed THHN/THWN copper conductors, this cable delivers durability, fire resistance, and compliance with NEC, UL, and IEEE standards. Its integrated green insulated grounding conductor ensures safe fault-current management, while the aluminum armor reduces weight by up to 45% compared to steel-clad alternatives.

Key Features

  • Lightweight Aluminum Armor: Interlocked aluminum construction provides robust mechanical protection with reduced weight for easier handling.

  • THHN/THWN Copper Conductors: Rated 90°C dry/75°C wet, available in 14 AWG to 2 AWG sizes for versatile power and control applications.

  • Integrated Grounding: Includes a green-insulated copper grounding conductor for NEC compliance.

  • Fire & Hazard Resistance: Meets FT4/IEEE 1202 flame test (70,000 Btu/hr) and UL firestop system certifications (1-3 hours).

  • Installation Efficiency: Saves up to 50% labor costs vs. conduit systems; reverse-wound on reels for pull-friendly deployment.
