12/2 MC Cable with Ground 100FT - 12AWG Metal Clad Cable

In this review of the 12/2 MC Cable with Ground 100FT, the bottom line is clear: this cable is aimed at electricians, contractors, and serious DIYers who need a durable, NEC-compliant run for branch circuits where exposed or concealed metal-clad cable is required. The reviewer found the biggest reason to buy is the industrial-grade interlocked aluminum armor combined with THHN/THWN 12AWG conductors and a full 12AWG ground, which together deliver a reliably protected, 600V-rated feed suitable for HVAC, lighting, and general power distribution.

Key Features

• Type THHN/THWN conductors: Provides standard stranded insulation suitable for dry and wet locations up to the rated temperatures, helping ensure long-term performance in common electrical installations.
• Heavy-duty metal armor: Industrial-grade interlocked aluminum armor shields conductors from corrosion, moisture, and physical damage, which is important for exposed runs in commercial or industrial spaces.
• NEC Article 330 compliance: Built to meet NEC standards for MC cable, so it can be used reliably in HVAC, lighting runs, and branch circuits where code-compliant metal clad cable is required.
• High-purity copper conductors: 99.99% oxygen-free copper ensures good conductivity and reduced oxidation risk, supporting stable power delivery over the cable length.
• Heat and moisture ratings: Rated for 90C dry and 75C wet at 600V, giving flexibility for a range of building environments and higher temperature applications.

Who It's For

This cable is best for licensed electricians, electrical contractors, and experienced DIYers who need a 100 ft length of 12AWG two-conductor plus ground MC cable for commercial, industrial, or qualified residential projects. It suits branch circuits feeding motors, HVAC equipment, or lighting where metal-clad protection and UL listings are required.

Those who should look elsewhere include homeowners needing only short runs for simple indoor outlets where standard NM cable would be more economical, or installers who require flexible liquid-tight conduit cable for constant movement applications.

Pros & Cons

Pros

• Well-protected by interlocked aluminum armor, offering robust physical and moisture protection.
• Conductor construction uses high-purity copper and THHN/THWN insulation, yielding good conductivity and reliability.
• UL-listed and RoHS-compliant, matching common job-site safety and environmental expectations.
• 600V rating and 90C dry temperature rating allow for a range of commercial uses.

Cons

• Armor and construction make the cable heavier and less flexible than non-armored alternatives, which can complicate tight pulls.
• As an MC cable, it is overkill for simple indoor residential circuits where lighter NM cable would do.

Specifications

Our Verdict

The 12/2 MC Cable with Ground 100FT is a practical, code-conscious choice for professionals who need a durable, UL-listed metal-clad run with solid copper conductors and a full 12AWG ground. It represents good value where armor protection and NEC compliance matter, while installers should note the reduced flexibility compared with non-armored cable.

Frequently Asked Questions

Can this cable be used outdoors?
It is rated for dry and wet locations per its THHN/THWN and NEC applicability, but outdoor exposed installation should follow local code and routing practices to prevent unnecessary corrosion.

Is the ground the same size as the conductors?
Yes, the ground wire is 12AWG, matching the conductor size for proper grounding in branch-circuit applications.

Does the cable meet UL and environmental standards?
Yes, it is UL-listed (UL 83, UL 1569, UL 2556) and RoHS environmental grade compliant.
