1/0-3 MC Cable – Three-Conductor 1/0 AWG Metal Clad Cable for High-Capacity Three-Phase Power Distribution

1/0-3 MC Cable features three color-coded 1/0 AWG copper conductors and a ground wire, all enclosed in a heavy-duty aluminum interlocked armor. It is designed for large-scale electrical infrastructure requiring high ampacity three-phase power without a separate neutral conductor, such as motor feeders and industrial equipment connections.

It is designed for large-scale electrical infrastructure requiring high ampacity three-phase power without a separate neutral conductor, such as motor feeders and industrial equipment connections.

Typical Applications of 1/0-3 MC Cable

  • Three-phase motor feeder circuits
  • Industrial machinery power supply
  • Manufacturing equipment connections
  • Large air conditioning and refrigeration units
  • Three-phase distribution panels without neutral loads

Advantages of Using 1/0-3 MC Cable

  • High Current Capacity: Handles substantial three-phase loads
  • Armor Protection: Built-in mechanical protection without conduit
  • Cost-Effective: Three-conductor design reduces material costs
  • Easy Installation: Flexible armor simplifies routing and pulling

FAQs

Q: What's the ampacity of 1/0-3 MC Cable? A: Typically around 150–170 amps depending on installation conditions. Always consult NEC ampacity tables for specific applications.

Q: Can this be used for single-phase applications? A: Yes, though it may be oversized. Two conductors can be used with the third as spare.

Q: Is conduit required with this cable? A: No, the interlocked aluminum armor provides mechanical protection, eliminating conduit requirements in most installations.
