This VN Infinite Quality 12/2 MC aluminum cable (50 ft) continues the focus on firestop compatibility and reduced installation costs. It carries a UL classification for firestop systems and uses lightweight aluminum armor to ease handling. The 12-gauge, two-conductor configuration makes it suitable for standard residential and light commercial circuits where fire resistance is a requirement.
VN Infinite Quality 12/2 MC Alum Cable 25 Ft
Note: This entry appears twice in the catalog above with the same product focus; the 25-foot version highlights cost savings, lightweight aluminum armor, and firestop compatibility. It remains a viable option where shorter runs and versatile mounting paths are necessary, especially in multi-space projects with fire-rated requirements.
Buying Guide: Key Purchase Considerations For 2 Hour Fire Rated MC Cable
When selecting 2-hour fire-rated MC cable, consider the following factors to ensure compliance and optimal performance.
- Conductor material: Copper conductors offer excellent conductivity but may raise cost versus aluminum. Choose based on load requirements and local codes.
- Armor material: Aluminum armor reduces weight and simplifies installation, while steel armor may offer greater abrasion resistance for rough environments.
- Fire-stop classifications: Verify UL or equivalent ratings for through-penetration firestop systems (1-, 2-, or 3-hour). This ensures compatibility with fire-rated assemblies in walls, floors, and ceilings.
- Diameter and bending radius: Ensure cable fits within conduit or raceways and can navigate joists or obstacles without compromising insulation integrity.
- Voltage rating and ampacity: Match the cable’s ratings to the circuit requirements and local electrical codes for safe operation.
- Installation environment: Consider indoor vs. outdoor exposure, moisture, and chemical resistance. Aluminum armor can be more sensitive to certain environments than copper conductors.
- Manufacturers and warranties: Reputable brands often provide documentation and support for fire-rated installations, reducing site disputes and inspection delays.
- Code compliance: Always cross-check with the latest NEC guidelines and local amendments to ensure the selected MC cable meets required fire-resistance and installation standards.
- Ease of installation: Lighter cables with flexible armor may reduce labor time but verify compatibility with existing trays, clamps, and raceways.
Fire-rated MC cables are engineered to maintain circuit integrity during fire exposure, helping to safeguard occupants and property. The options above emphasize UL classifications, aluminum vs copper trade-offs, and practical installation considerations for American projects. Compare lengths, weight, and handling characteristics to determine the best fit for new builds, renovations, or retrofit applications in both commercial and residential settings.
