12/3 MC Cable - Heavy-Duty Metal Clad Cable for Demanding Electrical Applications
12/3 MC Cable is a robust and flexible metal clad electrical wire designed for both commercial and industrial branch circuit wiring. With three 12 AWG conductors and a ground wire enclosed in a protective metallic armor, this cable offers enhanced safety, performance, and versatility for more complex wiring setups.
Common Uses for 12/3 MC Cable
- Three-way switch wiring
- Split receptacle circuits
- Multi-circuit power runs in commercial buildings
- Lighting control systems
- Industrial equipment wiring
Why Choose 12/3 MC Cable?
- Multiple Conductors: Allows for more complex circuits in a single cable run
- Metal Clad Armor: Offers mechanical protection and eliminates the need for conduit in many installations
- Fire and Moisture Resistance: Suitable for dry locations with excellent insulation and protection
- Time and Labor Saving: Quick installation in walls, ceilings, and cable trays
Frequently Asked Questions
Q: What does '12/3' mean in MC cable?
A: It refers to three 12-gauge insulated conductors, commonly color-coded black, white, and red, plus one ground wire.
Q: Can I use 12/3 MC Cable for outdoor applications?
A: Standard MC cable is designed for indoor use. For outdoor or wet environments, look for MC cable with a PVC jacket or use MC-HL rated cable.
Q: What’s the difference between 12/2 and 12/3 MC Cable?
A: 12/2 has two insulated conductors (black & white), while 12/3 has three (black, white, red), allowing for more advanced circuit configurations.
Q: Is 12/3 MC Cable allowed in residential installations?
A: Yes, especially in multi-family buildings, apartment complexes, and for specific circuit designs like three-way switches.
