Caution: 8 AWG is larger; ensure fittings and spaces can accommodate the gauge and armor diameter.
Buying Guide
What is bare armored ground cable, and when should I use it?
Bare armored ground cable, often called metal-clad (MC) cable, combines copper conductors with an aluminum or steel armor that protects the wires from physical damage. It is ideal for indoor, outdoor, and underground installations where protection from moisture, abrasion, and impact is needed, along with a reliable grounding path.
Key considerations when choosing MC cable
- Conductor size and gauge: Choose based on current requirements and circuit protection.
- Armor type: Aluminum armor is lightweight and durable; steel armor offers maximum protection but is stiffer.
- Voltage and temperature rating: Ensure the rating matches your installation environment and equipment.
- Grounding conductor: Verify the presence and size of the dedicated ground conductor.
- Installation environment: Indoor vs. outdoor, exposure to moisture, heat, or chemicals.
Comparison at a glance
- Best for long, protected runs: FIRMERST 12/2 MC Cable with Ground (long length, aluminum armor)
- Best for rugged protection: Armored Metal Clad Cable with Ground (stainless spiral armor, versatile indoors/outdoors)
- Best for short outdoor/underground runs: 12/2 MC Cable with Ground 50 FT (compact length, copper conductors)

Installation tips and cautions
- Plan bends and routes to minimize stress on armor and conductors.
- Follow local electrical codes for enclosure, junctions, and terminations.
- Inspect armor for any nicks or deformation before pulling conductors.
- Use appropriate connectors and clamps rated for armor cable to ensure secure transitions.
Frequently asked questions
- What is MC cable with ground best used for? – It is used for reliably protected power runs in indoor, outdoor, and underground installations where durability and grounding are important.
- Can I run MC cable in wet locations? – Yes, many MC cables are rated for wet conditions, but verify the specific temperature and moisture ratings for your product.
- How do I determine the right gauge? – Choose based on current requirements, length of run, and allowable voltage drop for the circuit.
- Is aluminum armor better than steel armor? – Aluminum armor is lighter and easier to install; steel armor offers maximum protection but is heavier and stiffer.
- Do these cables require special connectors? – Yes, use connectors compatible with armored cable and rated for the specific diameter and voltage.
