4/2 MC Cable – Two-Conductor Metal Clad Cable for Heavy-Duty Power Circuits
4/2 MC Cable consists of two 4 AWG copper conductors and a ground wire, all protected by a rugged interlocked aluminum armor. It is widely used in commercial and industrial applications where a two-conductor, high-amperage circuit is needed.
Common Applications for 4/2 MC Cable
- Single-phase 240V or 208V power feeds
- HVAC systems, including rooftop units
- Heavy-duty appliances and equipment
- Branch circuits in industrial or warehouse settings
Benefits of 4/2 MC Cable
- High Ampacity: Suitable for circuits requiring 85–95 amps, depending on installation factors
- Durable Armor: Protects conductors from mechanical damage
- Faster Installation: No need for additional conduit in most indoor settings
- Code-Approved: Meets NEC requirements for commercial wiring
Frequently Asked Questions
Q: What’s the amp rating of 4/2 MC Cable?
A: It can handle approximately 85–95 amps, depending on ambient temperature and number of current-carrying conductors.
Q: Can 4/2 MC Cable be used underground?
A: Not unless it is rated for direct burial or used in conduit. Consider MC-HL or PVC-jacketed options for wet or buried installations.
Q: What does “4/2” mean in MC Cable?
A: It indicates two conductors of 4 AWG size. It does not include a neutral conductor, only hot wires and a ground.
