| Product | Best For | Why It Stands Out | Limitations |
|---|---|---|---|
| VN Infinite quality MC Cable 10/2 | Professional electricians on indoor runs | Durable aluminum armor and solid copper core for safety and longevity | 25 ft length may require splicing for longer runs |
| Woods 25′ 12/2 MC ALUM Cable | Mid-size commercial and residential projects | Lightweight aluminum armor reduces installation effort; firestop rated | UL classifications not detailed in listing |
| VN Infinite quality 12/2 MC Alum Cable | Cost-conscious installations with fire safety needs | Significant cost savings, lighter weight, UL firestop compatibility | 25 ft length limits longer runs unless spliced |
| FIRMERST 10/2 MC Cable with Ground | Garage, workshop, or external installations | Solid copper with ground; factory-assembled for faster installs | 10 AWG size may limit some high-load circuits |
| AIRTAK Round 18 Cu.in. PVC Old Work Box | Retrofit ceiling installations with fire-rated walls | Tool-free old-work installation; built-in grounding features | Box is not a cable, but supports safe, compliant terminations in fire-rated spaces |
VN Infinite quality MC Cable 10/2 – Indoor Use
Features include rugged aluminum armor that shields the cable from physical damage and harsh indoor environments, a high-conductivity solid copper core, and an integrated ground wire. The cable is designed for easy installation and bending in tight spaces, making it suitable for professional projects where speed matters. Best for: interior runs in commercial or residential spaces where durability and reliable conductivity are critical. Limitation: 25 ft length may necessitate splices for longer runs.
Woods 25′ 12/2 MC ALUM Cable
This option emphasizes cost-efficiency and lighter installation thanks to aluminum armor. It aims to reduce installation costs and weight compared with steel MC cable, with UL Classifications for various firestop scenarios. Best for: projects prioritizing lighter weight and lower installation costs in spaces that require 1-, 2-, or 3-hour fire-rated through-penetration systems. Limitation: The listing does not detail exact fire rating classes per model beyond through-penetration systems.
VN Infinite quality 12/2 MC Alum Cable (25 Ft)
Designed for cost-effective installation, this 12/2 MC alum cable weighs less than steel MC, saving time and labor on commercial and industrial sites. It is UL Classified for 1, 2, and 3-hour through-penetration firestop systems, adding a tier of fire safety to a range of installations. Best for: projects needing lighter-weight, easier-handling MC cable with firestop compliance. Limitation: Some environments demand higher conductor counts or different gauges than 12/2 provides.
FIRMERST 10/2 MC Cable with Ground
This cable integrates 10 AWG solid copper conductors with a grounded conductor and aluminum armor for abrasion resistance and protection in exposed runs. The factory-assembled design reduces parts and steps, speeding up renovation or new installations. Best for: sites needing a robust, ready-to-use MC cable with clear hot, neutral, and ground identification. Limitation: 10 AWG capacity may not support all high-current applications without confirming load calculations.
AIRTAK Round 18 Cu.in. PVC Old Work Box
Though a box rather than cable, it complements fire-rated installations by providing tool-free old-work ceiling mounting with integrated grounding provisions. It is designed to work with NM-B, MC, and UF cables, fitting NEC grounding requirements and offering living hinges for quick cable entry. Best for: retrofits in fire-rated spaces where reliable cabling termination and grounding are needed. Limitation: Not a cable itself, but essential for compliant terminations in ceiling installations.
Buying Guide: Key Considerations for 2 Hour Fire Rated MC Cable
- Conductor size and amperage: Choose gauge size (e.g., 10/2, 12/2) based on load requirements and local codes.
- Armor material: Aluminum armor reduces weight; steel armor can offer extra durability but adds weight.
- Fire-stop compatibility: Confirm UL classifications for through-penetration firestop systems relevant to the project.
- Length and handling: Longer runs may require more joints; consider available lengths and ease of pulling cable.
- Grounding and safety: Ensure integrated or separate grounding conductors meet NEC requirements.
- Installation environment: Indoor vs. exposed runs; exposure to moisture or physical impact can influence armor choice.
- Code compliance: Verify the product’s listed fire ratings align with the specific fire-rated wall or floor assembly in your project.
FAQ
- What does 2 hour fire rated MC cable mean?
– It refers to cables designed to maintain circuit integrity under fire conditions for about two hours, typically used where fire-rated barriers exist. - Is aluminum armor as durable as steel for MC cable?
– Aluminum armor is lighter and easier to handle, with excellent corrosion resistance; steel armor offers higher physical protection but adds weight. - Can I use 12/2 MC cable for all circuits?
– 12/2 is common for lighting and general circuits; confirm current requirements and code allowances for each installation. - Do fire-rated MC cables require special termination?
– Yes, many require compatible firestop systems and proper terminations in fire-rated assemblies; always verify with local codes. - Should I buy longer MC cable than needed?
– If possible, choose lengths that minimize joints, but ensure you have enough slack and plan for future changes.
