3/3 MC Cable – Three-Conductor Metal Clad Cable for 3-Phase Power Distribution
3/3 MC Cable features three 3 AWG copper conductors and a ground wire, enclosed in a protective aluminum armor. It is ideal for three-phase power systems in commercial and industrial environments.
Common Applications for 3/3 MC Cable
- Three-phase power distribution
- Feeder circuits in commercial buildings
- Power supply to motors, HVAC units, and industrial equipment
- Industrial lighting and heavy-duty branch circuits
Benefits of 3/3 MC Cable
- Supports Three-Phase Loads: Ideal for balanced three-phase 208V or 480V systems
- Rugged Construction: Withstands physical damage and harsh conditions
- Time-Saving Installations: Eliminates need for conduit in most dry locations
- Code-Compliant: Meets UL and NEC requirements
Frequently Asked Questions
Q: What does 3/3 MC Cable mean?
A: It contains three insulated 3 AWG conductors plus a ground. This makes it suitable for three-phase applications without a neutral.
Q: Can I use 3/3 MC Cable for single-phase power?
A: It's designed for three-phase, but you could use only two conductors if a neutral isn't needed—though 3/2 or 2/2 might be more cost-effective.
Q: Is 3/3 MC Cable rated for wet locations?
A: Standard MC Cable is for dry locations. For wet locations, consider MC-HL or PVC-jacketed MC cables.
