YDDECW 100FT 8/2 MC Cable With Ground
This cable uses an aluminum alloy jacket and solid copper conductors with a dedicated ground wire. It is rated for 600V and designed for harsh outdoor environments up to 90°C. It meets UL 83, UL 1569, and UL 2556, offering corrosion resistance and robust heat handling. Best for industrial or outdoor runs where physical protection and long-term reliability are priorities. Caution: the aluminum armor adds stiffness; plan bends carefully to avoid damage in tight spaces.
XRDS -RF 75FT 8 AWG/2 MC Cable
Features high-purity 8 AWG stranded power conductors paired with a solid green ground and a flexible aluminum interlocking armor. This design emphasizes ease of maneuverability during installation while maintaining solid protection. It is engineered to UL 83, UL 1569, and UL 2556 standards for professional electrical projects. Best for projects needing both flexibility and strong grounding. Limitation: stranded conductors may be slightly less resistant to abrasion than solid-core variants in very rough environments.
Stock Wire 100FT 8/2 MC Cable With Ground
This option emphasizes multi-application use, suitable for branch, feeder, and service distribution in commercial, industrial, and multi-residential builds. It features an aluminum jacket for protection and is rated for up to 55 Amps. Best for projects requiring a balance of protection and current-carrying capacity. Caution: ensure the 55 Amp rating aligns with the local electrical design and circuit breaker sizing.
YDDECW 25FT 8/2 MC Cable With Ground
Compact variant with heavy-duty aluminum armor and solid copper conductors. Suited for shorter runs or tight installations in outdoor environments. Best for service entries or equipment hookups where space is limited. Caution: shorter length may require more joints for longer runs, which can affect installation time.
MOOKEERF 10FT 8/2 MC Cable
Type THHN/THWN conductors with a nylon-insulated inner surface and an aluminum alloy outer jacket. Maximum temperature ratings reach up to 90°C dry and 75°C wet, with a RoHS-compliant build and UL listings. Best for high-heat, EMI-prone environments where additional insulation and durability are needed. Limitation: higher insulation complexity may affect cost and install time.
Buying Guide: Key Considerations For 8/2 MC Cable
What should you check before buying? Material and protection level are essential. Aluminum armor or jacket provides outdoor resilience and flexibility, while copper conductors offer superior conductivity and heat dissipation. Consider the installation environment—outdoor, underground, or indoor—and the corresponding temperature and moisture exposure.
- Conductor Type: Solid versus stranded copper. Solid conductors are durable for fixed routes; stranded copper offers better flexibility for bends and complex runs.
- Armor vs Jacket: Aluminum armor is rugged for physical protection; an aluminum jacket is lighter and still protective but may offer different bend radii.
- Grounding: Ensure there is an integrated ground conductor and confirm grounding method to meet local codes.
- Temperature Rating: Verify maximum dry/wet temperatures to match the installation environment and equipment insulation.
- Voltage Rating and Ampacity: Typical ratings around 600V; match ampacity to circuit load and breaker sizing.
- Code Compliance: Look for UL listings (UL 83, UL 1569, UL 2556) and ensure compatibility with your project specs.
FAQ
What does 8/2 MC stand for?
8/2 MC refers to eight-gauge conductors with two insulated current-carrying conductors and a grounding conductor, all enclosed in a metal-clad armor cable designed for protected installations.
Is aluminum armor as durable as steel armor?
Aluminum armor provides excellent corrosion resistance, flexibility, and lighter weight, making it suitable for many outdoor applications. Steel armor offers higher mechanical strength but is heavier and more conductive to corrosion unless properly treated.
Can I run MC cable outdoors without conduit?
In many jurisdictions, MC cables with proper armor are rated for outdoor use and can be run in certain environments without conduit, but always confirm local electrical codes and installation requirements.
What is the difference between a jacket and armor in MC cables?
The jacket is the outermost layer that protects against moisture and environmental exposure; armor is a rigid metallic layer that provides physical protection against impact and crushing in harsher environments.
