“An excellent choice for commercial service entrance conductors, primary building feeders, and heavy industrial branch circuits. Engineered as a Type MC certified assembly, this 3-conductor plus bare ground system features high-capacity 600V cross-linked polyethylene (XHHW-2) insulated conductors encased within a rugged, lightweight interlocked aluminum armor shield.”

Key Features & Benefits: 1 AWG 3 Conductor Aluminum MC Armor Cable

When wiring industrial plants, multi-residential complexes, or commercial retail grids, balancing physical protection and labor time is paramount. The 1 AWG 3-Conductor Aluminum MC Cable offers a highly cost-effective, lightweight alternative to heavy copper building wires in rigid pipe systems.

Fabricated with Class B compact stranded AA-8000 series aluminum alloy, the assembly features individual Cross-Linked Polyethylene (XLPE) insulated wires wrapped securely in structural binder tape before armor application. It functions effortlessly under extreme dry heat, environments requiring high impact resistance, and specialized environmental air-handling plenum spaces while preserving excellent installation bend flexibility.

Common 1-1-1-4 Aluminum MC Cable

• Commercial & Industrial Feeders: The premier choice for running high-capacity feeder panels through commercial warehouses, casinos, manufacturing plants, and institutional facilities.

• Service Entrance Conductor Lateral Loops: Extensively deployed to route secondary service power feeds from main enclosures out to independent electrical distribution hubs.

• Environmental Plenum Applications: Certified by code for open deployment inside multi-story vertical structural risers and environmental air-handling plenums.

• Heavy HVAC Conditioning Infrastructure: Ideal for wiring high-capacity commercial climate control grids, industrial building chillers, and large refrigeration equipment blocks.

• Cost-Conscious Commercial Retrofits: Eliminates the grueling step of bending, anchoring, and pulling wire through commercial EMT or rigid steel conduit pipe.

Technical Note: All values are nominal and subject to industry tolerances and manufacturer corrections. Specifications are subject to change without notice. It is the buyers responsibility to verify that all materials meet the specific requirements of the project and comply with local electrical codes.

Ampacity Note: Values calculated based on the National Electrical Code (NEC) ampacity standards. Because most commercial distribution panels, main breakers, and terminal lugs for 100-Amp circuits feature standard 75C termination points, circuits should be designed around the conservative 100-Amp limit. The 115-Amp rating at 90C is utilized for ampacity adjustment, crowding adjustments, and correction factors.
