Southwire 12/3 Solid Copper Armorlite MC Cable
Product features include premium copper conductors rated for 90°C dry environments (12 gauge) with a green insulated grounding conductor for safety. Aluminum armor provides mechanical protection and flexibility in exposed or concealed installations, including cable trays and approved raceways. Best for: commercial, industrial, or multi-residential projects requiring sturdy power, lighting, and control wiring. Limitation: ensure compatibility with THHN/THWN insulation in your conduit plan.
Armor lite Type Mc Aluminum Armored Cable, 12/3
Features note soft drawn copper conductors and a 600-volt rating, with installation suitability in cable trays and approved raceways. Best for: installations prioritizing straightforward tray or raceway mounting. Limitation: data only mentions copper conductors without the complete insulation details, which may affect compatibility in certain environments.
12/3 MC Cable with Ground 100 ft
This 12 AWG aluminum armored cable uses four copper conductors (three current-carrying plus a ground) with a 600V rating. It emphasizes safety, high conductivity, and corrosion resistance. Best for: indoor, outdoor, and underground installations requiring reliable grounding and high current capacity. Limitation: the description highlights copper conductors but does not specify insulation type, which may affect temperature handling in specific environments.
Solid Metal Clad 12/3 Cable with Ground 250 Feet
Durable aluminum armored design with stranded copper conductor and ground wire. Best for: heavy-duty residential or commercial wiring where flexibility and protection from environmental factors are needed. Limitation: data notes stranded copper, which may differ from solid conductors in terms of conductor stiffness for tight bends.
12/3 Metal Clad Cable with Ground 50ft
Outdoor-ready 12/3 with aluminum armor and solid copper conductors. Best for: embedded installations and outdoor wiring where quick deployment over shorter runs is needed. Limitation: shorter length may require more splices or additional terminations for larger projects.
Buying Guide
- What is MC cable 12/3? A metal-clad cable with four conductors (three current-carrying plus a ground) used for power, lighting, and control circuits in residential, commercial, and industrial settings.
- Aluminum armor vs. other armor types: Aluminum armor offers corrosion resistance, flexibility, and protection against physical damage, making it suitable for harsh environments and exposed installations.
- Conductor material: Copper conductors provide high conductivity and current capacity. Solid copper conducts consistency matters for voltage drop, while stranded copper offers flexibility for bends and installations.
- Where to install: Use MC 12/3 in cable trays, approved raceways, outdoor runs, and underground or indoor applications as permitted by local codes and the product’s UL listings.
- Voltage and temperature ratings: Ensure the product rating (typically 600V, 90°C dry) matches your project requirements and environmental conditions.
- Installation considerations: Check bend radii, allowable installation paths, and compatibility with THHN/THWN insulation when applicable.
FAQ
- What does 12/3 indicate in MC cable? It indicates four conductors (three current-carrying plus a ground) with a 12-gauge conductor size.
- Is aluminum armor suitable for outdoor use? Yes, aluminum armor provides corrosion resistance and protection in outdoor and harsh environments when the product is rated for outdoor use.
- What is the voltage rating of these cables? Most options are rated for 600V, suitable for many branch and feeder applications.
- Can I install MC cable in conduit or trays? Yes, MC cable is designed for use in cable trays and approved raceways in addition to direct burial or outdoor runs where allowed.
- Do these cables require special connectors? Use compatible MC cable connectors and clamps rated for aluminum armor and copper conductors per local electrical codes.
- How do I choose between solid vs. stranded copper conductors? Solid copper works well for fixed installations with fewer bends, while stranded copper offers better flexibility for complex routing.
