Southwire 12/2 Solid 16/2 Solid MC-PCS Duo Cable
The Southwire MC-PCS Duo cable is designed for branch power distribution across commercial, industrial, institutional, or multi-residential buildings. It supports power, lighting, control, and signal circuits and is commonly used as luminary cable in LED lighting with 0-10V dimming systems. Its dual-purpose construction can simplify installations by combining multiple circuits into a single armored run, reducing conduit requirements and enhancing mechanical protection in harsh environments.
Key features to consider include conductor material, voltage rating, and compatibility with dimming systems. The 12/2 configuration with 0-10V dimming compatibility is ideal for LED lighting projects, while the solid copper conductors provide reliable conductivity. For longer runs or rugged environments, ensure the armor and jacket meet weather and mechanical protection needs. This cable is UL-listed and suited for indoor and some outdoor applications, depending on local codes.
Southwire 68580055 250 ft 12/2 Solid CU MC Lite Cable
The MC Lite version offers 12/2 solid copper conductors in a lighter aluminum armor, enabling easier handling for installers while still providing solid electrical performance. It is well-suited for residential or commercial runs where lighter weight and flexibility are prioritized without sacrificing safety. The aluminum armor provides corrosion resistance in varied environments while maintaining good bendability for tight installations.
Considerations include how much protection you need from moisture, radiation, or physical abrasion, and whether a lighter armor fits your project constraints. As with other MC cables, confirm voltage rating and conductor size align with circuit demands, and verify local code compatibility before running long interior or exterior sections.
Southwire 68580052 50-Foot 12-Gauge 2-Conductor MC Cable Aluminum
This 12/2 MC aluminum cable offers two current-carrying conductors with aluminum armor, designed for efficient routing through trays and approved raceways. The cable’s construction emphasizes ease of installation because the conductors are soft drawn copper, cabled together with a binder tape and printed legend, providing a straightforward path through complex layouts. It’s suitable for shorter runs where a robust, weather-resistant armored cable is necessary yet weight savings are beneficial.
Important factors include bend radius, allowable exposure (indoor, outdoor, or tray-only), and whether aluminum armor supports your mounting or enclosure plan. Match the installation method to the cable’s rated use and ensure full compliance with local electrical codes for safety and reliability.
12/2 MC Cable With Ground 100 Ft (Aluminum Armor)
This MC cable features three solid copper conductors (two current-carrying and one ground) with aluminum armor, rated for up to 600V and temperatures up to 90°C dry / 75°C wet. UL listed, it is designed for both indoor and outdoor underground installations where armor protection is a priority. The 100 ft length is suitable for medium-range runs, while the robust armor helps resist moisture, humidity, and mechanical damage in outdoor environments.
When using this option, assess the line length, environmental exposure, and whether the armor’s corrosion resistance aligns with your site’s climate. Proper termination and protection at terminations are essential to maximize safety and longevity in outdoor or buried installations.
12/2 MC Cable With Ground 250 Ft (Aluminum Armor)
This 250 ft MC cable equips three solid copper conductors with aluminum armor and a 600V rating, designed for longer outdoor or underground runs. As with other MC cables, UL listing and corrosion resistance are critical advantages in exposed environments. The length reduces the need for splices, which can improve reliability in complex installations. Always verify that the overall run length and armor type comply with local code requirements and enclosure protection specifications.
HONENCN 16 Gauge 2 Conductor Low-Voltage Cable (CCA)
This 16 AWG, 2-conductor wire uses copper-clad aluminum conductors for low-voltage applications (12V-24V) such as LED strips and automotive lighting. It is lightweight, flexible, and easy to strip or solder, with good conductivity for short to medium runs. While not a full MC cable, it complements 12/2 and 16/2 MC options by serving lower-voltage lighting or signaling needs in the same project. Consider insulation rating, voltage use-case, and compatibility with your planned terminations and connectors.
Buying Guide: Key Considerations For 12/2 And 16/2 MC Cables
When selecting MC cables for 12/2 or 16/2 configurations, consider these core factors to optimize performance and compliance:
- Conductor material: Copper conductors deliver reliable conductivity; aluminum armor is common for protection and environmental resistance. Solid conductors reduce skin effect losses and improve current capacity for these gauge sizes.
- Armor type and rating: Aluminum armor is lighter and corrosion-resistant, while steel armor offers maximum protection in harsh environments. Verify weather exposure, temperature, and code requirements for your installation.
- Voltage and temperature ratings: Typical MC cables for these sizes are rated around 600V and 75–90°C. Ensure the rating matches your circuit and ambient conditions, especially for outdoor or underground runs.
- Installation method: Cable trays, approved raceways, and direct burial considerations affect choice. Bend radius, ease of pulling, and mechanical protection influence long-term reliability.
- Length and splices: Choosing longer runs minimizes splices, reducing potential failure points. Plan terminations and connectors compatible with the chosen armor and conductors.
- Compliance: Confirm UL listing and adherence to local electrical codes (NEC requirements, weatherproofing, and outdoor installation rules). Documentation and labeling are essential for inspections.
- Application scope: Distinguish between lighting, power, and control circuits. For LED dimming and signaling, ensure compatibility with dimmers and control gear specified for the project.
In summary, the right MC cable choice balances mechanical protection, electrical performance, and installation practicality. For longer outdoor or underground runs, prioritize armor type and ruggedization. For interior, controlled environments, lighter MC options may reduce weight and ease handling without compromising safety. Always verify project-specific code requirements and consult a licensed electrician when in doubt.
