12/3 MC Cable with Ground 100FT 12AWG - Metal Clad 600V Cable

In this review the 12/3 MC Cable with Ground from MOOKEERF is assessed for contractors and serious DIYers who need durable, code-compliant metal clad wire for demanding installations. The bottom line: it is best for commercial and residential branch circuits where protection and UL listings matter, thanks to its metal interlocked armor, THHN/THWN conductors and 600V rating. The reviewer found the cable offers reliable conductivity and physical protection for exposed or concealed runs when a tough, NEC-compliant solution is required.

Key Features

• Type THHN/THWN conductors: Provides versatile insulation rated for both dry and wet locations up to 90C dry and 75C wet for many building uses.
• 12AWG conductors plus ground: Three 12 gauge conductors and a 12 gauge ground deliver consistent current capacity for typical branch circuits and HVAC feeds.
• Industrial metal armor: Steel interlocked armor shields the conductors from corrosion, moisture and physical damage in harsher jobsite environments.
• UL listed and NEC compliant: Meets UL 83, UL 1569 and UL 2556 and aligns with NEC Article 330 for exposed or concealed use where MC cable is required.
• High-purity copper: 99.99% oxygen-free copper conductors offer improved conductivity and reduced oxidation risk over long runs.
• Fire-resistant insulation: UL-listed insulation and metal sheath withstand elevated temperatures, useful in commercial wiring and factory installations.

Who It's For

The cable is aimed at electricians, contractors and advanced DIYers installing branch circuits, lighting, HVAC runs or feeding equipment where a rugged, code-approved MC cable is required. It suits projects that need a 600V rated, NEC-compliant cable with the convenience of factory-applied conductors in a preassembled metal clad form.

Those who should look elsewhere include homeowners with only light indoor low-voltage needs or installers who must use conduit-only THHN instead of MC cable; projects that require flexible, nonmetallic wiring or different ampacity should evaluate alternate conductor sizes or cable types.

Pros & Cons

Pros

• Durable metal armor protects conductors from physical damage and moisture.
• UL-listed THHN/THWN conductors and multiple UL standards provide confidence for inspection and code compliance.
• High-purity copper and nylon-covered insulation improve conductivity and wear resistance over time.

Cons

• Heavier and less flexible than nonmetallic cable, making long tight bends or retrofit through finished spaces more difficult.

Our Verdict

The MOOKEERF 12/3 MC Cable with Ground is a practical, code-aware choice for installers who need a robust 600V metal clad cable with proven UL listings and reliable copper conductors. It represents good value for commercial and residential branch circuits where protection and inspection approval matter, though it sacrifices some flexibility compared with nonmetallic options.

Frequently Asked Questions

Is this cable suitable for wet locations?
Yes, the THHN/THWN conductors are rated for wet locations at 75C and the armor adds a moisture-resistant layer for many installations.

Does this cable meet NEC requirements for exposed runs?
Yes, it is designed to meet NEC Article 330 standards for exposed and concealed installations when MC cable is permitted.

What temperature can the cable withstand?
The cable is rated to 90C in dry conditions and 75C in wet conditions, matching typical THHN/THWN temperature limits.
