12/3 MC Cable with Ground 25FT 12AWG Metal Clad MC Cable - Durable

In this review of the 12/3 MC Cable with Ground, the bottom line is simple: this cable is aimed at electricians and contractors who need a rugged, NEC-compliant option for commercial or heavy residential runs. The single biggest reason to buy is the industrial-grade interlocked metal armor combined with UL-listed THHN/THWN conductors, which together deliver reliable protection and long-term conductivity in exposed or concealed installations. This review highlights durability, code compliance, and practical field use.

Key Features

• Type THHN/THWN conductors: Provides familiar, heat- and moisture-rated conductors for a wide range of wiring applications up to 600V.
• 12AWG conductors with ground: Three 12 gauge conductors plus a 12AWG ground give a solid balance of ampacity and flexibility for branch circuits and equipment feeds.
• Heavy-duty metal armor: Industrial-grade steel interlocked armor shields the cable from physical damage, corrosion, and moisture in demanding environments.
• High temperature rating: Insulation and sheath withstand up to 90C dry and 75C wet, allowing safe use in many commercial and industrial settings.
• Multiple UL listings and RoHS: UL 83, UL 1569 and UL 2556 listings plus RoHS environmental grade mean the cable meets recognized safety and material standards.

Who It's For

Electricians, contractors, and facility maintenance teams who install HVAC, lighting, branch circuits, or equipment feeds in commercial buildings, garages, or factories will find this 12/3 MC cable particularly useful. Its metal clad armor and UL-listed conductors make it a good choice for exposed runs where durability and NEC Article 330 compliance matter.

Homeowners doing small DIY projects or runs in easily accessible finished walls may prefer simpler nonmetallic cable options for lower cost and easier handling; this MC cable is best where extra physical protection and industrial ratings are required.

Pros & Cons

Pros

• Robust interlocked steel armor that guards conductors from impact and moisture during installation and service.
• UL-listed THHN/THWN conductors and 600V rating provide reliable electrical performance and broad application.
• Good conductivity from high-purity copper conductors and a full 12AWG ground for safety.

Cons

• Armored MC cable is heavier and less flexible than nonmetallic cable, which can make routing in tight spaces more difficult.
