12/3 MC Cable
JZD Cable’s 12/3 MC Cable is a UL-listed, aluminum-interlocked armored cable designed for reliable power distribution in demanding environments. This 12 AWG, 3-conductor + ground configuration provides two hot wires, one neutral, and a dedicated ground—ideal for three-way switching, split receptacles, and shared-neutral circuits. Fully compliant with UL 1569, NEC Article 330, and NFPA 70, it delivers 600V voltage capacity with a 90°C dry / 75°C wet temperature rating.
Key Features:
✅ UL Certification: Meets UL 83, UL 1479 (firestop), UL 1569, and UL 1581 standards.
✅ Robust Construction: Solid copper conductors with THHN/THWN-2 insulation for moisture/chemical resistance.
✅ Aluminum Interlocked Armor: Lightweight, corrosion-resistant, and crush-proof—no conduit required.
✅ Fire-Rated: Listed for 1‑, 2‑, and 3‑hour through‑penetration firestop systems (UL 1479).
✅ Easy Installation: Pre‑lubricated armor simplifies pulling; anti‑short bushing not needed.
