“A dependable industrial and commercial choice for high-amperage feeder systems, branch circuits, and secondary sub-panel installations. Engineered with a lightweight, interlocking aluminum armor jacket, this pre-protected 3-conductor plus ground assembly eliminates the extensive material and labor expenses of traditional conduit piping. It allows electrical crews to route heavy service lines directly through walls, ceilings, and open cable trays in a fraction of the time.”

Key Features & Benefits: 3/0-3 Aluminum MC Cable w/ Ground

3/0 3-Conductor Aluminum Metal Clad (MC) Cable delivers a completely code-compliant, pre-armored wiring solution designed to minimize field labor hours and maximize jobsite efficiency. Featuring three compact-stranded AA-8000 series aluminum phase conductors insulated with cross-linked polyethylene (XLPE/XHHW-2) and a dedicated bare grounding wire, the assembly is protected by an overall interlocking aluminum armor jacket.

• Labor-Saving Armor: The integrated aluminum interlocked armor serves as its own flexible metallic protective raceway, removing the tedious labor of bending and installing separate EMT or rigid conduit systems.

• AA-8000 Conductor Material: Manufactured with compact-stranded 8000-series aluminum alloy to ensure high electrical conductivity, dramatically reduced weight strain during long structural pulls, and excellent flexibility.

• XHHW-2 Insulation: Individual phase conductors are insulated with cross-linked polyethylene (XLPE), providing elite resistance to heat, moisture, and electrical stress in challenging industrial environments.

• Maximum Versatility: Code-approved for an exceptionally broad range of heavy-duty installations including commercial distribution panels, large equipment feeders, vertical risers, and environmental air-handling spaces (plenums).

• Cut to Length or Bulk Spools: Order custom cut-to-length footage to eliminate jobsite waste, or select full factory spools and reels for major commercial installation pulls.

Common 3/0 3-Conductor Alum MC Cable Applications

• 150A175A Sub-Panel Feeds: Primary feeder lines running from main service disconnects to 150A or 175A sub-panels in commercial buildings, workshop facilities, and multi-tenant complexes.

• Heavy HVAC & Industrial Equipment: Dedicated power feeds for 3-phase commercial rooftop HVAC units (RTUs), chillers, industrial air compressors, and heavy machinery not requiring a neutral conductor.

• Open Plenum & Drop-Ceiling Routing: Fully certified under NEC 300.22 for routing directly through environmental air-handling plenum spaces, dropped ceiling voids, and raised floors without conduit.

• Commercial EV Charging & Transformers: Reliable power distribution for commercial EV charging hubs, step-down transformers, and large battery storage feeds.

• Multi-Story Vertical Shafts: Approved for vertical riser shafts in commercial structures and high-rise facilities when secured per NEC 300.19 and 330.30 guidelines.

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. Reference NEC Article 330 for specific Metal-Clad installation guidelines.

Ampacity Note: Values calculated based on National Electrical Code (NEC) standards. Because most standard commercial electrical panels, breakers, and terminal lugs feature 75C termination points, circuits are typically designed based on the conservative 155-Amp standard. The 175-Amp rating at 90C is highly utilized for ampacity adjustment and correction factors.
