"A dependable industrial and commercial choice for heavy 3-phase feeder systems, branch circuits, and main service sub-panel installations requiring a neutral conductor and an upsizing 400 MCM grounding conductor. Engineered with a lightweight, interlocking aluminum armor jacket, this pre-protected 4-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."
600 MCM 4-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 four compact-stranded AA-8000 series aluminum phase conductors insulated with cross-linked polyethylene (XLPE/XHHW-2) and a dedicated 400 MCM 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.
Heavy-Duty 400 MCM Ground: Includes a full 400 MCM bare aluminum ground wire to satisfy demanding engineer specifications, high fault-current grounding requirements, and NEC parallel feeder guidelines.

600 MCM 4C Aluminum MC Cable is primarily used for 3-phase, 4-wire power distribution, main service disconnects, and heavy feeder circuits in commercial and industrial facilities. The 4-conductor setup provides three hot phase conductors, a dedicated full-sized neutral, and a bare grounding conductor (such as 400 MCM or 1/0 AWG depending on spec). It is commonly specified for supplying power to 350A/400A subpanels, 3-phase commercial equipment, and HVAC systems requiring neutral connections without conduit pipe.
No. Standard 600 MCM 4C Aluminum MC cable with open, interlocked metal armor is engineered strictly for dry, indoor, concealed, or exposed installations. It cannot be buried directly in soil or embedded in concrete without a protective, fluid-tight PVC outer jacket (often designated as "Direct Burial MC" or "PVC-Jacketed MC"). For underground runs without conduit, a jacketed MC cable or direct-burial cable (like URD or USE-2) is required.
The primary differences come down to weight, cost, and ampacity. Copper is a more efficient conductor, meaning 600 MCM Copper MC is rated for 420 Amps (75°C), whereas 600 MCM Aluminum MC is rated for 340 Amps (75°C). However, 600 MCM Aluminum MC is dramatically lighter and significantly more cost-effective, making it the clear economic choice for long commercial feeder runs where a 340A capacity satisfies the electrical load.
Wire America supplies an extensive inventory of 600 MCM 4C Aluminum MC cable cut by the foot or on master reels. Most cut-to-length orders are processed and shipped within 24 to 48 hours, delivering directly to your shop or jobsite within 2 to 4 business days once in transit.
We route your order from the regional distribution hub with stock closest to your jobsite to keep transit times and freight costs as low as possible. Expedited shipping options are also available at checkout.

Under National Electrical Code (NEC) guidelines, the allowable ampacity of 600 MCM 4C Aluminum MC Cable is 340 Amps @ 75°C and 385 Amps @ 90°C.
*Ampacities are based on NEC Table 310.16 for three current-carrying insulated conductors in a raceway or cable based on an ambient temperature of 30°C (86°F). Because standard equipment terminal lugs are rated at 75°C, most circuits are sized based on the 340-Amp rating. Note that if all four conductors are current-carrying (such as with major non-linear 3-phase loads), NEC ampacity derating factors (80%) may apply.
600 MCM 4C Aluminum MC Cable has an approximate physical net weight of 3,507 lbs per 1,000 feet (lbs/mft). The nominal outside diameter over the external interlocking aluminum armor is 2.80 inches (+/- 5%). Knowing these dimensions allows installers to select the appropriate trade-size connector fittings and evaluate structural weight strain for long cable tray pulls.
Yes, it is highly recommended. While modern AA-8000 series aluminum alloy is extremely stable, electrical best practice dictates applying an approved anti-oxidant paste (such as Noalox or Penetrox) onto stripped 600 MCM aluminum conductor ends before securing them into mechanical lugs or breaker terminations. This prevents oxidation from forming a resistive film over the connection point, ensuring a long-lasting, cool-running termination.
