Buying Guide
- Conductor Material: Copper conductors offer better conductivity and heat dissipation than aluminum, but may come at a higher cost. Aluminum armor jackets provide corrosion resistance and weight advantages for outdoor installations.
- Armor Type: Steel interlocked armor delivers higher protection against physical damage and moisture in harsh environments; aluminum armor provides flexible, weather-resistant protection suitable for outdoor conditions.
- Temperature Rating: Look for cables rated to at least 90°C dry/75°C wet for reliable operation in spaces with elevated temperatures or moisture exposure.
- Voltage Rating and NEC Compliance: Ensure the cable is rated at 600V and compliant with NEC Article 330 for exposed or concealed use in dry/wet locations to meet code requirements.
- Conductor Count and Grounding: An 8/3 MC cable includes three 8 AWG conductors plus a 10 AWG ground; confirm ground sizing aligns with local electrical codes and equipment requirements.
- Length Considerations: Longer runs may incur voltage drop; plan lengths to minimize loss and choose feeds or junctions accordingly.
- Environmental Conditions: For harsh or outdoor environments, aluminum armor jackets improve weather resistance, while steel armor provides rugged protection in industrial sites.
- Installation Flexibility: Thicker jackets and armor can be stiffer; verify bend radius and pulling tensions match the installation constraints.
- Certifications: UL-listed cables with fire-resistant insulation offer added safety, particularly in commercial facilities and data centers.
- Warranty and Manufacturer Support: Consider brands that provide clear documentation, installation guides, and customer support for project planning.
