These selections cover common service entrance setups, including mid-length runs from the meter to the distribution panel. They’re all rated for 600 volts and designed for use in wet or dry locations, making them versatile for residential and light commercial applications.
Wirenco 2-2-2-4 Aluminum SER Cable (50FT)

Feature highlights: Above ground service entrance cable rated for 600 volts and 100 amps, suitable for both wet and dry locations. This aluminum SER assembly is a common choice when copper cost considerations are a factor, offering reliable conductivity with adequate insulation for service drops and meter-to-panel runs.
NASSAU ELECTRICAL SUPPLY 2-2-2-4 SER Aluminum Cable (100FT)

Feature highlights: Insulated conductor size 2-2-2-4 with four conductors; bare conductor size 4. This configuration aligns with typical service entrance wiring needs, enabling straightforward installation from the service point to the main panel while maintaining adequate insulation and voltage tolerance.
NASSAU ELECTRICAL SUPPLY 40′ 2/0-2/0-2/0-1 SER Aluminum Cable

Feature highlights: Insulated conductor size 2/0-2/0-2/0-1 with four conductors and bare conductor size 1. This length option is useful for shorter service runs where a combination of larger phase conductors and a smaller neutral/bare conductor is needed to meet applicable codes and amperage requirements.
NASSAU ELECTRICAL SUPPLY 50′ 1/0-1/0-1/0-2 SER Aluminum Cable

Feature highlights: Wire size 1/0-1/0-1/0 with bare conductor size 2 and four conductors. This configuration provides elevated ampacity for higher-load service setups and can be well-suited for larger residential or light commercial installations that require robust performance and flexibility in routing from the meter to panels.
NASSAU ELECTRICAL SUPPLY 150′ 2-2-2-4 SER Aluminum Cable

Feature highlights: Size 2-2-2 with a ground size of 4 AWG; aluminum conductor material. The extended length is ideal for longer service runs along exterior walls or for installations where the service point is far from the panel, still maintaining appropriate insulation and voltage protection for 600V systems.
Wirenco 2-2-2-4 Aluminum SER Cable (75FT)

Feature highlights: Similar to the 50-foot version, this 75-foot option provides additional flexibility for meter-to-panel runs that require a longer segment without splicing. Rated for 600V and 100 amps, it remains suitable for varied installation environments.
These options emphasize aluminum SER construction for cost-effective, heavy-duty service entrance cabling. Copper SER variants are less common in these specific listings, but copper options do exist with similarAWG specifications, offering lower resistance at a higher material cost. Aluminum SER cable remains a practical choice where ampacity and flexibility are essential for typical residential and light commercial service runs.
Buying Guide
Key considerations when selecting 2 AWG SER cable:
- Conductor Material: Aluminum vs copper. Aluminum is lighter and generally more affordable, with adequate ampacity for most residential service runs. Copper provides lower resistance and can be favored for long runs with higher voltage drop concerns, but tends to be pricier.
- Conductor Configuration: 2-2-2-4 indicates three phase conductors (two hot lines and a neutral) plus a ground. Ensure the bare conductor size and insulation meet your local electrical code requirements.
- Voltage Rating and Ampacity: Confirm the 600V rating aligns with your system. For service entrance cables, ensuring ampacity matches the service load and panel rating is essential to avoid overheating.
- Length and Routing: Longer runs require careful planning to minimize voltage drop and physical protection. Exterior routes may demand additional jacket protection or conduits depending on local codes.
- Environment: Cabinets, meter bases, and external enclosures impose conditions like moisture exposure. Cables rated for wet locations reduce corrosion risk and improve longevity.
- Code Compliance: Always verify that the selected cable type complies with NEC rules for service entrances, grounding, and insulation in your jurisdiction. Installation by a licensed electrician is recommended for safety and compliance.
- Cost vs Performance: Aluminum SER cables typically offer favorable pricing with solid performance for service drops. When budget allows and installation length or voltage drop is a concern, copper SER might be preferred.
Comparison at a glance:
- Best for general residential service, aluminum SER options (e.g., Wirenco and Nassau) provide reliable performance and versatility for lengths from 50 to 150 feet.
- Longer runs (150 ft) suit exterior installations where routing distance is substantial; consider impedance and potential voltage drop.
- Shorter cut variations (50–75 ft) are ideal for standard meters-to-panel configurations in typical homes.
Overall, selecting the right 2 AWG SER cable depends on your system’s load, run length, and environmental exposure. Using reputable brands with documented 600V rating and appropriate ampacity ensures a safe, code-compliant service entrance installation.
