8/3 MC Cable with Ground – 100FT

Product: 8/3 MC Cable with Ground, 100 ft. Conductor size: 8 AWG with a 10 AWG ground. Material: aluminum armor and steel interlocked armor. Temperature rating up to 90°C dry / 75°C wet. Voltage rating 600V. UL listed under UL 83, UL 1569, UL 2556. Best for commercial HVAC, lighting, and branch circuits in harsh environments. Choose this if you need a rugged, NEC-compliant option for longer runs in industrial settings. Caution: longer runs may require careful heat management and proper junctions to maintain ratings.
8/3 MC Cable with Ground – 50FT

Product: 8/3 MC Cable with Ground, 50 ft. Conductor size: 8 AWG; ground conductor 10 AWG. Temperature rating: 90°C dry / 75°C wet. UL-listed with fire-resistant insulation and metal sheath. Best for shorter runs in commercial buildings or residential basements where a durable, weather-resistant cable is needed. Better for limited spaces; avoid if long runs are required without multiple pull points.
8/3 Metal Clad Cable with Ground 75ft

Product: 8/3 Metal Clad Cable with Ground, 75 ft. 8 AWG stranded copper conductors with a 10 AWG ground. Aluminum armor jacket rated for 90°C. UL-listed to UL 83, UL 1569, and UL 2556. Best for outdoor exposure and industrial installations. Choose this if you want robust weather resistance in compact lengths; caution with complex runs that require more length for routing.
Nassau 250FT 8/3 Stranded MC Copper

Product: Nassau 250FT 8/3 Stranded MC Copper Conductor with Aluminum Armor. Grounding conductor AWG 10. 600V rating; RoHS environmental compliance. Weight approximately 335 lbs per 1000 ft. Best for long outdoor or indoor runs requiring durable armor and copper conductors. Choose this for long, static installations; caution with heavier weight and handling over long pulls.
Buying Guide
- Application environment: Indoor, outdoor, underground, or exposed locations require armor and jacket materials that resist moisture, corrosion, and impact. Aluminum armor is common for outdoor use, while steel armor offers higher abrasion resistance.
- Conductor size and current needs: 8 AWG supports higher currents; ensure the cable length and voltage drop are within acceptable limits for the load and run. For shorter, lower-load runs, 12 AWG or smaller may suffice, but 8/3 is preferred for heavier loads.
- Temperature rating: Dry locations typically tolerate higher temperatures. For wet locations, verify ratings (75°C) to ensure safety under operating conditions.
- Code compliance: NEC Article 330 compliance is common for exposed or concealed use. Ensure listings such as UL 83, UL 1569, and UL 2556 apply to your project requirements.
- Length considerations: Longer runs increase voltage drop risk and require careful planning with pull points, junctions, and possible cooling strategies. For very long runs, sectional splices at rated boxes may be preferable.
- Ease of installation: Flexible copper conductors and lighter armor can simplify bending and routing. Be mindful of weight for 250 ft spools and plan for hardware supports and clamps.
Frequently Asked Questions
- What does MC stand for? MC stands for Metal Clad cable, which includes metal armor for protection and insulation around conductors.
- Is 8/3 the right size? 8/3 indicates eight-gauge conductors with three current-carrying conductors plus a ground, suitable for higher-load circuits and longer runs in many commercial and residential applications.
- Can MC cable be used outdoors? Yes, many MC cables feature aluminum armor and weather-resistant jackets, but confirm the product’s listing for outdoor use and the specific installation location.
- What is the difference between 8/3 and 12/3 cables? 8/3 uses thicker copper conductors for higher current capacity; 12/3 is thinner and suitable for lighter loads. 12/3 may be more flexible and less expensive, but supports lower amperage than 8/3.
- Do these cables require specialized connectors? Yes, MC cables typically require listed connectors and fittings compatible with metal-clad armor and the specific conduit or box types used in the installation.
- What is the typical voltage rating for these cables? Most listed MC cables for these lengths are rated at 600V, suitable for many residential and commercial circuits.
