Southwire Armorlite Type MC Aluminum Armored Cable, 14/2, 600 Volts
Key features include aluminum armor suitable for concealment or exposed installations, and use in cable trays or approved raceways. This option is best for commercial and multi-residential projects needing a robust, armor-protected run. The cable can simplify overhead or concealed wiring in structured building systems. It is especially advantageous where long, protected runs are required. Caution: ensure compatibility with installed raceways and tray systems to avoid bending or crushing the armor.
Southwire 14/2 SIMpull THHN THWN-2 Cable, 50 Feet
This product presents a compact option with THHN/THWN-2 copper conductors. It’s well-suited for shorter runs or where a more flexible pull through conduits is needed. It’s best for electricians working in controlled environments or installations where a standard non-armored but thermally rated cable fits the plan. Limitation: not a shielded MC armor cable, so pick this if armor protection isn’t required for the environment.
14/2 250FT MC Cable with Ground, Aluminum Armor
This cable combines UL-listed MC protection with a robust aluminum armor and solid copper conductors. It’s designed for indoor and outdoor use in industrial and commercial settings. The two-conductor 14/2 layout supports straightforward branch circuits with a ground conductor included. Caution: confirm temperature and environmental ratings (dry/wet) for your specific installation to maintain compliance and performance.
Southwire 14/2 MC Cable, 100 ft, Armorlite Aluminum Armor
This 100‑foot run offers lighter weight and easier handling compared to steel MC options, with aluminum armor suitable for many commercial and residential applications. It includes solid copper THHN/THWN conductors and a ground. Best for installations prioritizing ease of installation and reduced weight. Limitation: check firestop and enclosure requirements when used in dense building assemblies to ensure code compliance.
Buying Guide: How To Choose The Right 14/2 MC Cable
What matters most when selecting MC Cable 14/2? Start with environment, installation length, and protection needs. Armor type determines durability and where you can run the cable. Conductors must be copper for better conductivity and reliability. Temperature ratings influence where you can place the cables, especially in hot or damp environments. Grounding and insulation ratings, as well as UL listings, are critical for safety and code compliance.
Key considerations by scenario
- Residential indoor runs: Choose lighter armor, or Armorlite options for restricted spaces and easier routing.
- Commercial or multi-residential: Opt for aluminum armor MC cables that provide rugged protection in walls and ceilings.
- Indoor/outdoor: Look for weather-resistant armor and robust insulation ratings to withstand moisture and temperature variation.
- Long runs: Favor cables engineered for lower pull resistance and mechanical protection over long distances.
- Code compliance: Verify UL listings, temperature ratings, and suitability for dry or wet locations as required by local codes.
Comparison snapshot
- Best for long, protected runs in commercial spaces: Armorlite aluminum armor MC cables with 14/2.
- Better for shorter, flexible jobs: THHN/THWN-2 copper with no armor where flexibility matters.
- Choose this if lighter weight is a priority: Aluminum armor MC cables offer substantial weight savings over steel.
- Avoid this if you need heavy-duty resistance to physical damage and moisture: Non-armored conductors may not withstand harsh environments.
Installation tips
- Plan tray or raceway routing to minimize sharp bends that threaten armor integrity.
- Ensure proper grounding as specified for 14/2 configurations in your local electrical code.
- Use compatible connectors and fittings designed for aluminum armor where applicable.
- Check outdoor exposure and moisture exposure ratings to determine if additional protection is needed.
FAQ
- What does 14/2 MC cable include?
It includes two current-carrying conductors (hot and neutral) with a separate ground conductor, all inside a protective armor jacket.
- Is MC cable with aluminum armor suitable for outdoor use?
Yes, many aluminum armor MC cables are rated for indoor and outdoor use, depending on the specific product’s ratings and sealants.
- When should I choose THHN/THWN-2 conductors without armor?
When you require greater flexibility and are routing through existing conduit systems where armor is not necessary.
- What is a UL listing and why does it matter?
A UL listing confirms that the cable meets safety and performance standards, which is essential for code compliance and reliability.
- Can MC cable replace traditional conduit in all installations?
MC cable can replace conduit in many scenarios, but some installations may still require conduit for additional protection or code compliance.
- What environmental ratings should I verify?
Check temperature ratings (dry/wet), moisture resistance, and outdoor suitability to match your installation site.
