Metal Clad Cable 14/3 100 ft - Durable Indoor/Outdoor Power Wire

In this review of the Metal Clad Cable 14/3 100 ft, the bottom line is straightforward: this cable is for homeowners, electricians, and contractors who need a rugged, ready-to-install wiring option that can often remove the need for conduit. The reviewer found the combination of solid copper THHN/THWN-2 conductors, a stranded aluminum armor sheath, and a dedicated ground makes the cable especially suited to attic runs, outdoor feeders, and some underground embedded installations where durability and moisture resistance matter.

Key Features

• Three conductor configuration: Two solid copper conductor wires plus a dedicated ground provide a complete 14/3 circuit ready for switches and outlets without extra splicing.
• Aluminum interlocking armor: The metal clad sheath gives corrosion resistance and mechanical protection so the cable can be run exposed or embedded without conduit in many applications.
• THHN/THWN-2 insulation: Thermoplastic, high-heat, nylon-jacketed coatings on the copper conductors add heat and water resistance for indoor and outdoor use.
• 100 ft length: A full 100 ft spool reduces the need for joins on longer runs, saving time and lowering the chance of connection issues.
• UL certified wiring: Certification offers confidence the 14 AWG conductors meet common safety standards for typical residential and light commercial work.
• Time-saving installation: The armored cable often eliminates conduit installation, decreasing labor for many interior and exterior wiring runs.

Who It's For

This cable is a good fit for electricians, remodelers, and handy homeowners who need a tough, ready-to-run 14/3 cable for circuits to lighting, receptacles, or small appliance runs. It works well in attics, basements, garages, and many outdoor applications where a protective metal sheath and water-resistant insulation are beneficial.

Those who require very flexible multi-conductor cable, special low-voltage wiring, or sizes other than 14 AWG should look elsewhere. Also, for installations governed by unusual local codes, confirm that metal clad cable without conduit is acceptable before buying.

Pros & Cons

Pros

• Durable metal armor gives strong mechanical protection for exposed and embedded runs.
• Solid copper THHN/THWN-2 conductors offer reliable conductivity and heat/water resistance.
• Saves labor by often avoiding conduit installation for interior and exterior runs.
• 100 ft length covers most short-to-medium circuits without splicing.

Cons

• Less flexible than non-armored cable, which can make tight bends or retrofit runs more difficult.
• Not intended for specialty or very high-current circuits; limited to typical 14 AWG uses.

Our Verdict

The Metal Clad Cable 14/3 100 ft is a practical choice for anyone needing a sturdy, code-friendly 14 AWG circuit with built-in mechanical protection. It represents good value when conduit would otherwise be required, saving time on installation while providing durable, moisture-resistant conductors for a wide range of indoor and outdoor wiring tasks.

Frequently Asked Questions

Can this cable be run outdoors?
Yes, the THHN/THWN-2 insulation and aluminum armor make it suitable for outdoor runs where the installation method meets local code.

Is conduit always required with this cable?
No, one advantage of metal clad cable is that it often eliminates the need for conduit, though local codes and specific installation conditions may still require it.

Are the conductors copper or aluminum?
The conductors are solid copper with THHN/THWN-2 coating; the outer interlocking armor is aluminum.
