Wirenco 4/0 AWG XHHW-2 aluminum building wire provides UL 44 and ASTM B800/B801 compliance and compact stranded conductor construction. Rated for up to 205 amps at 90°C, it suits branch circuits and service feeders in both commercial and residential projects requiring flexible, high-ampacity aluminum conductors.
Wirenco 4/0 AWG XHHW-2 125 Ft
This Wirenco 125-foot cut of 4/0 AWG XHHW-2 aluminum wire provides similar UL and ASTM certifications with extended length for longer runs. Its compact, stranded construction supports easier pulling and installation in conduit and underground ducts while offering strong high-temperature performance.
Nassau Wake Forest URD 80′ Cable
This 80-foot Wake Forest URD cable presents a compact option for shorter URD installations with the same 4/0 phase and 2/0 neutral configuration. Its direct burial capabilities and voltage rating fit residential URD feeders and service drops where space is at a premium.
Nassau 50′ SER Aluminum Service Entrance
This SER aluminum service entrance cable uses four 4/0 AWG phase conductors with a 2/0 grounding conductor. It is designed for service entry applications, delivering reliable performance for feeders and main panels with 600V insulation suitability and aluminum conductors for economic efficiency.
Nassau 100′ Mobile Home Feeder
The 4/0-4/0-2/0-4 configuration supports feeder runs from a service to a mobile home panel. Grounding conductor size is 4 AWG, offering a robust setup for residential mobile home installations with 600V rating and aluminum conductors for cost-effective installation.
Buying Guide: Key Considerations For 4/0 AWG Aluminum Cables
- Insulation Type And Rating: XHHW-2 insulation offers high-temperature resistance and moisture tolerance, suitable for wet and dry environments. URD and SER cables have specific insulation for underground or service entrance use; confirm the intended installation environment (underground burial vs. above-ground service routes).
- Conductor Configuration: Quadruplex URD cables combine multiple phase and neutral conductors in a single sheath, saving space for underground runs. Triplex URD cables use three conductors with a separate neutral; SER cables include multiple phase conductors plus a grounding conductor. Choose the configuration that matches your panel or transformer connections.
- Ampacity And Voltage Rating: Ensure the ampacity matches the expected load and that the cable is rated for the system voltage (commonly 600V for these products). For high-amp residential feeders and mobile home feeders, verify that the insulation and conductor sizing meet local code requirements.
- Length And Flexibility: Longer runs reduce number of splices but can complicate pulling. Shorter lengths may require fittings and additional terminations. Check whether the product is offered in the exact length you need or if cut-to-length options are available (as with Wirenco options).
- Certification And Standards: Look for UL 44/UL 67 compatibility, ASTM B800/B801 for aluminum conductors, and other relevant certifications to ensure safety and code compliance.
- Installation Environment: For URD cables, ensure proper burial practices, moisture protection, and trenching considerations. For SER and mobile home feeders, ensure appropriate protection against physical damage and correct outer jacket wiring protection.
- Brand And Support: Reputable brands like Nassau Electrical Supply and Wirenco often provide product documentation, compatibility information, and customer support that can assist during planning and installation.
- Cost Implications: Aluminum conductors offer cost advantages over copper but may require specific connectors and termination hardware. Factor in total install cost, including protective conduits, clamps, and terminations.
