Nassau Electrical Supply 50′ 2/0-2/0-2/0-1 SER Copper Cable
Product details and suitability: This copper SER cable features conductors sized 2/0-2/0-2/0-1 with a nominal outer diameter of 1332 mils. It is designed for service entrances, panels, and feeders in both residential and light commercial settings. Copper conductors offer high reliability under load, with robust conductivity and long-term performance in varied environments. The 19 phase conductors configuration aligns with common SER service setups while maintaining flexibility for routing through walls and conduit runs. Applicable for 600V systems with appropriate enclosure and grounding practices. Always verify local code requirements and weather considerations when installing exterior runs or underground sections.
Nassau Electrical Supply 1/0-1/0-1/0-2 SER Copper Cable (50FT)
Product details and suitability: This copper SER cable uses 1/0-1/0-1/0-2 AWG conductors and a 1235 mil outside diameter, with annealed soft copper for flexibility during installation. The copper makeup supports efficient current transfer and durable performance for service feeder applications. Suitable for 600V installations, it provides a reliable option for main feeders and panel connections where copper conductors are preferred for their conductivity and resistance to corrosion. Ensure correct conductor count and grounding conductor sizing per local electrical codes.
Wirenco 2/0-2/0-2/0-1 SER Aluminum Service Entrance Cable (50 Foot Cut)
Product details and suitability: This SER cable is aluminum-based and rated for 600V, suitable for above-ground service entrances, panel feeders, and branch circuits. While aluminum offers cost benefits and good conductivity, it requires careful handling to avoid oxidation and ensure secure termination. The 50-foot cut length makes it convenient for shorter runs or specific installation segments. Consider copper alternatives if maximum conductivity and compatibility with copper terminals are a priority in your project.
Relaxweex 100′ 1/0-1/0-1/0-2 SER Aluminum Service Entrance Cable
Product details and suitability: This three-conductor plus one exposed neutral/ground aluminum SER cable supports high-load feeder applications with a 90°C insulation rating and a sun-resistant PVC sheath for weather tolerance. It provides flexibility for longer runs and direct burial considerations in dry or damp ground. The aluminum construction offers a balance between cost and performance, but copper would generally be preferred where maximum conductivity and long-term stability are required. This option is helpful for cost-conscious installations or projects where aluminum SER is specified by design.
NASSAU ELECTRICAL SUPPLY 50′ 4/0-4/0-2/0-4 Aluminum Mobile Home Feeder Cable 600V
Product details and suitability: This aluminum mobile home feeder cable features a 4/0-4/0-2/0-4 configuration, designed for larger feeder applications requiring higher ampacity. While not copper, it is relevant for comparison and planning when copper feeders are impractical due to cost or availability constraints. Ensure compliance with local codes for above-ground and underground sections, grounding conductor sizing, and appropriate protection against moisture and UV exposure where applicable.
Buying Guide: Key Considerations for 2/0 SER Copper and Related Cables
- Conductor material: Copper SER cables offer superior conductivity, corrosion resistance, and long-term stability. Aluminum SER can be cost-effective but requires careful termination and anti-oxidation practices. Choose copper when code and budget allow for higher reliability and performance.
- Conductor size and ampacity: Verify the correct AWG and conductor count for your project’s load requirements. Common 2/0 SER copper configurations support substantial feeder loads but must align with panel ratings and local codes.
- Voltage rating and environment: Most SER cables are rated for 600V. Consider weather exposure, direct burial needs, and whether a sun-resistant sheath or moisture protection is required for outdoor runs.
- Insulation and temperature ratings: Look for insulation rated at 90°C or higher for high-temperature environments or long-term cabinet seating. This improves performance in hot climates and near electrical heat sources.
- Mechanical flexibility: Copper SER cables with annealed copper and flexible insulation are easier to install around corners and through conduits. Aluminum SER cables can be more rigid, requiring planning for bends and support.
- Code compliance and termination: Ensure that conductor sizes, grounding conductors, and protective devices meet NEC and local code requirements. Use compatible lugs, connectors, and panels rated for the selected conductor material.
- Cost versus efficiency: Copper offers superior conductivity but at a higher cost. Aluminum SER may be acceptable for certain applications where amperage and budget constraints are balanced, provided code approvals are met.
In summary, copper SER cables such as the Nassau 50′ 2/0-2/0-2/0-1 or the Nassau 50′ 1/0-1/0-1/0-2 are strong choices for robust service entrances requiring copper conductors. Aluminum SER options in the set provide useful benchmarks for comparison and budgeting, while still meeting many installation needs in the right contexts. Always cross-check with local codes and professional guidance to ensure a compliant and safe installation.
