Southwire 12/2 MC Lite Aluminum Armored Cable (68580055)
The Southwire 68580055 MC Lite cable combines copper conductors with aluminum armor to deliver a lightweight, flexible solution for power distribution. Encased in a corrosion-resistant armor jacket, this 12/2 configuration is designed for use in cable trays or approved raceways, offering practical performance for residential and light commercial wiring projects. The MC Lite designation implies a balance of protection and ease of install, particularly in areas with restricted clearance or where conduit is less desirable.
Armor lite MC Aluminum Armored Cable, 12/3
This Armor lite MC aluminum armored cable features 12/3 conductors, providing an extra circuit within a single armored assembly for easier routing in complex installations. With a 600-volt rating and copper conductors, it supports branch circuits, feeds, and equipment connections in commercial spaces where durable protection and straightforward installation are priorities. It’s suitable for both concealed and exposed installations when installed in approved raceways or cable trays.
Southwire Armorlite MC Aluminum Armored Cable, 14/2
The Armorlite 14/2 MC aluminum armored cable is designed to distribute power in commercial, industrial, and residential buildings. Its aluminum armor provides protection against physical damage, while the copper conductors ensure reliable conductivity for typical 600V circuits. The product is suitable for concealed or exposed runs and installation in cable trays and approved raceways, making it versatile for various building projects.
Woods 12/2 MC Aluminum Cable, 100 ft
The Woods 68580023 12/2 MC Aluminum Cable emphasizes U.S.-made quality and reduced installation costs through lighter aluminum armor. It is designed for power distribution in residential and commercial settings where ease of handling and installation speed matter. The aluminum armor adds protection against physical damage while keeping the overall weight manageable for easier pulling and routing through structures.
12/2 MC Armored Cable With Ground (50 ft)
This 12/2 MC Armored Cable with Ground provides a complete grounding conductor alongside three 12 AWG solid copper conductors wrapped in flexible metal armor. The armored design adds durability for commercial and residential wiring runs, supporting up to 600 volts. Its three-conductor plus ground configuration is widely used for branch circuits, feeders, and service connections in environments requiring robust protection against physical damage.
Buying Guide: Key Considerations For High-Voltage MC Cable
When choosing MC cable for high-voltage applications, consider the following perspectives to ensure safety, code compliance, and performance across environments.
- Voltage rating and conductor material: Most MC cables listed here are rated for 600V, suitable for typical branch circuits and feeders. Copper conductors offer excellent conductivity and durability, while aluminum armor reduces weight and can lower installation time in some scenarios.
- Armor type and field conditions: Aluminum armor provides corrosion resistance and lighter weight but may be less rigid than steel armor. For high-traffic or exposed installations, armored cables protect conductors from physical damage.
- Conductor count and layout: 12/2 and 12/3 configurations cover common single-phase circuits and small multi-wire distributions. For larger or more complex layouts, higher conductor counts along with appropriate grounding are advisable.
- Cable trays and raceways compatibility: Many MC cables are designed for installation in cable trays and approved raceways. Ensure your installation method aligns with local codes and manufacturer guidelines.
- Environmental conditions: Outdoor, sun exposure, and temperature extremes affect cable performance. Some options advertise UV resistance and temperature tolerances suitable for harsh environments.
- Code compliance and local requirements: Installations should meet NEC or applicable local codes. Check for listed approvals and proper labeling for the intended installation environment.
- Ease of installation: Lighter MC Lite variants can simplify pulls in tight spaces, while more rugged armor offers superior protection in high-damage zones. Consider the balance between flexibility and protection for the project.
- Cost versus durability: While aluminum armor tends to be lighter and potentially less costly, copper conductors provide robust conductivity. Weigh upfront costs against long-term reliability and installation time.
In evaluating these options, align product features with project needs—voltage requirements, aisle or corridor routing, exposure to physical impact, and whether installation will be indoors or outdoors. The chosen cables provide a spectrum of protection levels and conductor configurations to support a wide range of high-voltage, metal-clad wiring applications.
