Buying Guide: Key Purchase Considerations
- Voltage and ampacity: Ensure the cable is rated for 600V and meets your required amperage (commonly 100A for service feeders).
- Conductor size and configuration: 2-2-2-4 and 6-6-6-6 are common for service entrances and URD applications; verify the exact conductor count and gauge for your system.
- Direct burial suitability: Look for jackets and insulation rated for direct burial (XHHW-2 insulation, PVC jackets) to resist moisture, UV exposure, and abrasion.
- Operating temperature: A higher continuous operating temperature (such as 90°C) supports better performance in hot environments.
- Length and routing: Choose lengths that minimize splices and conduits. Longer runs require careful trenching planning and moisture protection at terminations.
- Environmental considerations: Corrosion resistance and moisture resistance are important for outdoor and underground installations.
- Standards and compatibility: Confirm compliance with local electrical codes and compatibility with your panels, meters, and service equipment.
- Cost vs. durability: While direct burial wires reduce conduit needs, ensure the jacket and conductor design align with long-term reliability for outdoor exposures.
These guidelines help compare options across brands and lengths, ensuring you select a cable that fits code requirements, installation conditions, and power needs. Always follow local regulations and consult a licensed electrician for complex outdoor electrical projects.
