14/3 MC Cable – Three-Conductor 14 AWG Metal Clad Cable for Multi-Way Switching and Lighting Circuits
14/3 MC Cable includes three color-coded 14 AWG copper conductors (black, white, and red) along with a ground wire, enclosed in a rugged interlocked aluminum armor. This configuration is ideal for multi-way switch lighting circuits, split receptacle wiring, and general branch circuits in commercial and residential settings.
Common Uses of 14/3 MC Cable
- Three-way and four-way light switch circuits
- Split outlet branch circuits
- General lighting control in homes and commercial offices
- Light-duty appliance wiring
- Interior walls, ceilings, and raised floors
Benefits of Using 14/3 MC Cable
- Extra Conductor: Supports switch legs or shared neutral setups
- Reduced Conduit Need: Metal armor allows for direct installation
- Enhanced Durability: Mechanical protection in high-traffic or exposed areas
- Cost-Effective: Fewer conduit fittings and faster labor
FAQs
Q: Can I use 14/3 MC Cable for 20A circuits?
A: No, 14 AWG conductors are limited to 15 amps. For 20A circuits, use 12/3 MC Cable.
Q: What is the red wire used for?
A: Typically, the red wire serves as a traveler in multi-way switching setups or as a hot wire for split receptacles.
Q: Is this cable fire-rated?
A: It meets standard UL fire resistance requirements, but check local code for specific applications like plenum or riser spaces.
