Buying Guide
- Conductor material and rating: Look for 14 AWG solid bare copper conductors rated for 600V and high temperatures (such as 90°C) to ensure power capacity and safety in demanding installations.
- Armor and jacket: Aluminum interlocked armor provides corrosion resistance and physical protection. Consider weather exposure, moisture, and potential mechanical damage when selecting armor type.
- Indoor vs. outdoor suitability: For outdoor or underground use, prioritize MC cables with robust armor and a jacket designed to withstand UV exposure, humidity, and temperature changes.
- Code compliance: Check certifications and UL listings (e.g., UL 83, UL 1569, UL 2556) to ensure the product meets local electrical codes and safety standards.
- Length and installation practicality: Longer runs reduce splices but may demand more flexibility. Choose lengths that minimize waste while fitting your layout.
- Grounding considerations: Ensure a dedicated grounding conductor is included or properly added to comply with grounding requirements in your installation.
- Cost vs. durability: Aluminum armor tends to be durable and lighter than heavy steel armor, often offering a favorable balance for many projects.
- Manufacturer support and availability: Availability of spares, guidance documentation, and warranty terms can influence long-term project success.
