Wirenco 50 Ft 2/3 MC Cable With Ground — Aluminum Armor
This Wirenco product features aluminum armored, stranded copper conductors suitable for service power and feeder distribution in industrial and commercial settings. NEC 520.5 compliance allows use in theaters and studios. It offers ampacity ratings of 95 amps at 60C, 115 amps at 75C, and 130 amps at 90C, supporting a range of branch circuits and heavy-load feeds.
Wirenco 20 Ft 2/3 MC Cable With Ground — Aluminum Armor
Ideal for shorter feeders or constrained installations, this Wirenco 2/3 MC Cable shares the same aluminum armor and stranded copper conductors as longer variants. It supports service power and feeder applications across commercial and multi-residential buildings, with consistent ampacity ratings (95 A at 60C, 115 A at 75C, 130 A at 90C). The compact length aids in tight equipment rooms and conduit runs.
Wirenco 15 Ft 2/3 MC Cable With Ground
Short-length MC cable options can simplify installations in theater, studio, and audience-area zones. This 15-foot Wirenco variant maintains the same aluminum armor and copper conductor composition, with ampacity ratings of 95 A at 60C, 115 A at 75C, and 130 A at 90C. It is designed for reliable power distribution in demanding spaces while reducing unused cable length in room shoulders or riser spaces.
Southwire 250 Ft 12/2 Solid CU MC Lite Cable
This long-run MC Lite cable provides solid copper conductors and an aluminum outer jacket for efficient power and lighting feeders in large projects. The MC-AL designation indicates a shielded construction suitable for cable trays and approved raceways. It supports robust distribution in commercial and industrial environments where longer runs are common.
Southwire 50 Ft 12-Gauge 2-Conductor MC Cable
Designed for installations using cable trays and approved raceways, this 50-foot, 12-gauge, 2-conductor MC cable features soft-drawn conductors and a binder-taped assembly. The aluminum outer jacket provides protection in dynamic building environments, making it suitable for branch circuits, feeders, and control wiring in commercial spaces.
Southwire Woods Southwire 25 Ft 12-Gauge 3-Conductor MC Cable
Three-conductor MC cable variants support branch circuits, power distribution, and control wiring in institutional and multi-residential projects. Aluminum outer jackets and conductors sized for general-purpose applications make this option suitable for embedded installations in plaster or finished spaces where concealment is a priority.
Buying Guide: Key Purchase Considerations
- Conductor material and size: Most MC cables use copper conductors. Confirm gauge (e.g., 6 AWG, 12/2) and whether copper or aluminum conductors match your load requirements and local codes.
- Armor and outer jacket: Aluminum armor provides protection against physical damage and EMI effects; verify jacket material and compatibility with conduit or cable trays.
- Ampacity ratings: Check the rated ampacity at specified temperatures (commonly 60C, 75C, 90C) to ensure the cable meets circuit load demands.
- Code compliance: Ensure the product aligns with NEC sections relevant to your application (e.g., NEC 520.5 for theaters and studios).
- Length and installation context: Longer runs may require more voltage drop considerations; assess whether the cable is available in your required lengths and whether a shorter variant suits space constraints.
- Environmental and building use: Consider whether the installation is indoor, outdoor, or in wet locations, plus any requirements for RoHS or fire-resistance classifications.
- Brand reputation and support: Choosing from established brands can provide reliable performance data, documentation, and after-sale support.
In summary, when selecting 2/3 MC cable, prioritize conductor type and size, armor protection, ampacity at operating temperatures, and code compliance for the intended installation environment. The options above offer a range of lengths and conductor configurations to fit diverse commercial, industrial, and multi-residential wiring needs.
