Nassau Ramapo 100 Amp Direct Burial Cable
The Nassau Electrical Supply Ramapo 100 Amp direct burial cable uses aluminum URD conductors rated for 600 volts. This direct burial wire is designed for Ramapo-type service runs, offering robust ampacity suitable for residential feeders. The product supports 165 amps in direct burial, which provides a comfortable margin for typical 100 amp service installations. A key consideration is the trenching and burial requirements, along with matching conduit and protective measures to ensure long-term reliability in outdoor environments.
FairySandy 50 ft SER Aluminum Service Entrance Cable
This FairySandy SER aluminum service entrance cable features 1-1-1-3 conductors with a 600V rating. The 50 ft length provides flexibility for shorter feeder runs or mobile homes where a compact yet robust 100 amp service is required. The AA-8000 aluminum alloy conductors deliver good conductivity and flexibility, while the gray PVC jacket and XHHW-2 insulation contribute to durability in underground or outdoor installations. Suitable for direct burial in appropriate soil conditions.
FairySandy 75 ft SER Aluminum Service Entrance Cable
This 75 ft FairySandy SER cable mirrors the 50 ft variant with three insulated 1 AWG conductors and a bare ground conductor. The 600V rating and direct burial capability make it a solid choice for 100 amp service runs to feed a mobile home or a detached structure. Its high conductivity and flexibility are beneficial for challenging routing scenarios along with adequate burial protection when installed correctly.
Wirenco 100 ft SER Aluminum Service Entrance Cable
Wirenco’s 100 ft SER aluminum service entrance cable features a 2-2-2-4 configuration, designed for 600V service with 100A capability. This product is suitable for above-ground and underground installations and emphasizes durability in wet and dry locations. The longer length provides routing flexibility for larger properties or longer feeder runs, reducing the need for splicing or additional connectors.
Southwire 50-Amp Distribution Extension Cord
This Southwire distribution extension cord is a practical accessory for temporary power needs, distributing 50 amps across dual feeds with a rugged jacket. While not a 100 amp cable, it serves as a complementary solution for sites that require versatile power distribution alongside a primary 100 amp feed. The extension is oil-resistant and designed for generator or jobsite use, offering flexibility in temporary setups.
Buying Guide: Key Considerations For 100 Amp Cables
- Conductor Material: Aluminum vs. Copper — Aluminum SER cables are common for feeders and underground runs due to cost efficiency and adequate conductivity for 100A service, while copper offers lower resistance and greater durability in some installations. Consider local code requirements and soil conditions when choosing.
- Insulation And Jacket: Look for XHHW-2 insulation and a robust PVC jacket for outdoor or direct burial use. These features protect against moisture, UV exposure, and physical damage in harsh environments.
- Voltage Rating And Ampacity: Ensure the cable is rated for at least 600V with an ampacity of 100A or more. Some products advertise higher ampacity (e.g., 165A direct burial) which provides a safety margin and supports future expansion.
- Application: Direct burial vs. above-ground service entrances — direct burial cables are designed to be buried in soil, while SER cables can be used in service entrances and above-ground runs with proper protection and conduit.
- Length And Routing: Longer runs may introduce voltage drop. For 100A feeders, plan lengths efficiently to avoid unnecessary power loss, and consider intermediate junctions only if code-compliant and properly enclosed.
- Code Compliance: Verify compliance with local electrical codes and NEC guidelines. Use appropriate fittings, connectors, and protective enclosures when burying or routing cables through walls or enclosures.
- Durability For Mobile Homes: Mobile-home feeders typically require direct burial or SER cables designed for outdoor exposure. Choose conductors and insulation rated for outdoor use with corrosion resistance.
- Safety Features: Look for flexible conductors that resist kinking, UV-resistant jackets, and robust insulation to minimize damage during installation. Labeling and color-coding help with quick identification during maintenance.
- Installation Considerations: Burial depth, trench width, backfill material, and moisture control affect long-term performance. Professional installation is recommended for high-current feeders to ensure compliance and safety.
In summary, the selected 100 amp options emphasize reliable aluminum SER and direct burial cables, aligned with common residential and mobile-home installations. Always validate installation requirements with a qualified electrician and consult local codes before purchasing and installing any 100 amp service cable.
