Feeder MC Cable – Heavy-Duty Metal Clad Cable for Main Power Distribution

Feeder MC Cable is engineered for high-amperage power distribution applications in commercial and industrial facilities. Featuring large gauge conductors (1/0 AWG and larger) with robust interlocked armor, this cable delivers reliable power from service panels to distribution panels, large equipment, and major electrical loads.

This heavy-duty MC cable eliminates the need for conduit in many applications while providing superior mechanical protection and grounding continuity. The armored construction makes it ideal for cable tray installations, direct mounting, and areas where physical protection is critical.

Key Features

  • High Amperage Capacity – Large conductor sizes handle major electrical loads up to 1000+ amps
  • Robust Armor Protection – Heavy-duty interlocked armor resists physical damage and provides reliable grounding
  • Code Compliant Installation – Meets NEC requirements for feeder circuits without conduit
  • Flexible Routing – Can be installed in cable trays, direct mounted, or suspended from structure
  • Time-Saving Installation – Pre-assembled construction eliminates field wiring of individual conductors
  • Superior Grounding – Continuous armor provides excellent equipment grounding path

Common Applications

  • Main feeder circuits from service panels to distribution panels
  • Large motor and equipment connections (pumps, compressors, HVAC units)
  • Industrial machinery and production equipment feeds
  • Data center power distribution to PDUs and server racks
  • Hospital and healthcare facility power distribution
  • Manufacturing plant main distribution systems
  • Commercial building tenant feeder circuits
  • Elevator and escalator power feeds
  • Emergency generator connections

Construction Details

Conductors: Stranded copper or aluminum with XHHW-2/THWN-2 insulation for maximum current capacity
Armor: Heavy-duty interlocked aluminum or steel armor for superior mechanical protection
Grounding: Full-size equipment grounding conductor or armor grounding system
Jacket: Optional PVC outer jacket available for enhanced environmental protection

Available Configurations

  • 3-Conductor: 1/0 AWG through 1000 MCM (with ground)
  • 4-Conductor: 1/0 AWG through 750 MCM (with ground)
  • Parallel Conductor: Multiple conductors per phase for high amperage applications
  • Custom Configurations: Available for specific project requirements

Installation Advantages

Reduced Installation Time: Pre-assembled cable eliminates pulling individual conductors through conduit
Lower Material Costs: Eliminates need for large conduit, fittings, and pull boxes in many applications
Flexible Mounting: Suitable for cable tray, direct mounting, or suspended installation methods
Code Compliance: Meets NEC grounding and installation requirements without additional conduit

Why Choose Feeder MC Cable?

Reliability: Heavy-duty construction ensures long-term performance in demanding electrical applications
Safety: Continuous armor grounding and robust construction provide superior electrical safety
Efficiency: Large conductor sizes minimize voltage drop and power losses in long feeder runs
Cost-Effective: Lower total installed cost compared to conduit and wire installations

FAQs

Q: What's the difference between feeder MC cable and branch circuit MC cable?
A: Feeder MC cable uses larger conductors (1/0 and up) for high-amperage applications, while branch circuit MC cable typically uses smaller conductors (14-2 AWG) for individual circuits.

Q: Can feeder MC cable be used for service entrance applications?
A: Yes, when properly rated and installed according to NEC Article 230 requirements. Check local codes for specific service entrance applications.

Q: What's the maximum amperage rating for feeder MC cable?
A: Amperage rating depends on conductor size and installation conditions. Large parallel conductor configurations can handle 1000+ amps.

Q: Is feeder MC cable suitable for outdoor installations?
A: Standard feeder MC cable requires protection from moisture. For outdoor use, specify cables with appropriate wet location ratings and protective jackets.

Q: How do I determine the correct size feeder MC cable for my application?
A: Consult NEC ampacity tables and consider factors such as load requirements, voltage drop calculations, and installation conditions. Professional electrical design is recommended for large feeder applications.
