Nassau 50′ 4/0-4/0-2/0-4 Aluminum Mobile Home Feeder Cable
Provided by Nassau Electrical Supply, this 600V feeder cable uses a 4/0-4/0-2/0-4 conductor arrangement with a 4 AWG grounding conductor. It is designed for mobile home feeder runs and is suitable for outdoor use when installed per applicable electrical codes. The cable’s aluminum composition reduces weight and can support up to 200 amps in typical installations, depending on installation conditions and local code requirements. This length option is useful for shorter feeder routes or renovations where precise routing matters.
Nassau 150′ 4/0-4/0-2/0-4 Aluminum Mobile Home Feeder Cable
This extended-length option from Nassau Electrical Supply expands the same 4/0-4/0-2/0-4 conductor set with a 4 AWG ground, rated for 600V. The 150-foot span is suitable for longer runs between a service point and a mobile home disconnect or service panel. Users should verify ampacity in context with installation conditions, as actual allowable ampacity can vary with temperature, conduit, and routing. The product is compatible with standard outdoor installation practices for electrical service feeders.
Nassau 100′ 4/0-4/0-2/0-4 Aluminum Mobile Home Feeder Cable
This 100-foot Nassau feeder cable mirrors the standard 4/0-4/0-2/0-4 configuration with a 4 AWG grounding conductor for 600V service. It is designed for mobile home electrical feeders with aluminum conductors, offering a balance between length and ease of handling. Installers should confirm the cable’s ampacity in the field and ensure compliance with local electrical codes and the National Electrical Code requirements for service feeders and outdoor installations.
Nassau 50′ 4/0-4/0-4/0-2/0 SER Aluminum Service Entrance Cable
This Nassau SER cable uses multiple 4/0 conductors in an aluminum service entrance configuration, with a 2/0 grounding conductor. It is intended for service entrance applications, delivering power from the utility drop to the meter and onward to the distribution panel. The aluminum construction helps with weight and cost, while the three main 4/0 phase conductors support higher-amp applications when properly installed in conduit and according to code. Verify compatibility with your panel and service disconnect staging before use.
Wirenco 4/0-4/0-4/0-2/0 SER Aluminum Service Entrance Cable (15FT Cut)
Wirenco’s SER aluminum service entrance cable features three 4/0 phase conductors and a 2/0 ground. The 15-foot cut length is suitable for short runs between a meter base and a main distribution panel. The outside diameter and conductor count align with typical SEU/SER configurations for service feeders, and the aluminum composition keeps weight and cost in check. Installation should follow local electrical codes, including proper routing through outdoor enclosures and weatherproof conduit terminations.
Wirenco 4/0-4/0-4/0 Aluminum SEU Service Entrance Cable (15FT Cut)
This Wirenco SeU cable includes three 4/0 phase conductors and a 4/0 ground in a compact aluminum SEU configuration. The 15-foot cut length enables quick, precise installations from the service drop to the meter base and onward to the distribution panel. The extruded insulation and robust exterior construction support outdoor reliability, but as with all feeders, installation requires adherence to NEC guidelines, proper strain relief, and weatherproof terminations.
Nassau 100′ 4/0-4/0-4/0-2/0 Aluminum Mobile Home Feeder Cable
This Nassau feeder cable combines three 4/0 phase conductors plus a 2/0 grounding conductor in an aluminum mobile home feeder design. Rated for 600V, it provides a robust configuration for longer routing distances and higher ampacity needs, depending on installation parameters. Field installation should consider ambient temperature, conduit fill, and NEC ampacity tables to ensure safe operation and code compliance.
Buying Guide: Key Purchase Considerations for 4/0 Feeder Cables
- Conductor material: Aluminum vs copper affects weight, cost, and ampacity. Aluminum is common for feeders, but copper offers higher conductivity and flexibility in some installations.
- Ampacity and voltage rating: Check the cable’s listed ampacity and its 600V rating to match service requirements and local codes. Real-world ampacity depends on ambient temperature, enclosure, and conductor grouping.
- Conductor configuration: 4/0-4/0-2/0-4 or 4/0-4/0-4/0-2/0 SER/SER-type configurations influence grounding and neutral arrangements. Ensure compatibility with the service panel and grounding electrode system.
- Grounding arrangement: Most 4/0 feeders include a dedicated grounding conductor (often 4 AWG or 2/0). Verify that the grounding scheme complies with NEC requirements for service feeders.
- Service entrance vs mobile home feeders: SEU/SER cables are designed for service entrances and direct runs from the meter to the panel. Confirm the intended application and installation route.
- Outdoor suitability: Outdoor runs require weatherproof terminations, protective conduit, and resistance to moisture, UV exposure, and temperature variation. Choose jackets and insulation rated for outdoor use.
- Length and handling: Longer cables are heavier and more cumbersome to install. Plan routing with proper supports, pulls, and in-wall or in-conduit transitions.
- Code compliance: Always verify local amendments to the National Electrical Code (NEC) and obtain any necessary permits or inspections for service upgrades and feeder replacements.
- Installation considerations: Use appropriate lugs, connectors, and strain reliefs. Avoid sharp bends, keep conductor ends clean, and follow manufacturer installation instructions for termination hardware.
