NASSAU ELECTRICAL SUPPLY 40′ 2/0-2/0-2/0-1 SER Cable
This 40-foot SER aluminum service entrance cable features four insulated conductors sized 2/0-2/0-2/0-1 and a bare conductor of size 1. Its construction suits outdoor and indoor transitions from meter bases to service panels, providing a robust solution for 150 amp service runs. The four-conductor arrangement ensures separate hot, neutral, and ground paths, reducing interference and improving safety in conduit or direct burial installations where permitted by code.
Wirenco 2/0-2/0-2/0-1 SER Aluminum Service Entrance Cable (20 Foot Cut)
This 20-foot cut version of Wirenco’s SER cable is designed for precise installations where the service route requires shorter lengths. With 2/0-2/0-2/0-1 configuration, it supports four conductors for safe power delivery to the main panel. Rated up to 600 volts and 90°C, it is suitable for wet and dry locations, aligning with UL 854 standards for service entrance cables. The compact cut length is convenient for tight spaces or interior routing.
Wirenco 2/0-2/0-2/0-1 SER Aluminum Service Entrance Cable (40 Foot Cut)
This 40-foot cut model provides additional length for longer installations without unnecessary waste. Like the 20-foot version, it uses a 2/0-2/0-2/0-1 conductor array and is rated for 600 volts and 90°C, suitable for wet or dry locations. It is UL 854 certified for service entrances, offering a balance of flexibility and strength for mid-range projects that require more reach than a short cut but less than a full-length run.
Wirenco 2/0-2/0-2/0-1 SER Aluminum Service Entrance Cable (30 Foot Cut)
This 30-foot cut option is ideal for installations with moderate distances between the meter and panel. It maintains the same four-conductor layout and a 600-volt, 90°C rating for durability in both wet and dry environments. UL 854 compliance ensures it meets required safety and performance standards for service entrance use in residential and light commercial settings.
NASSAU ELECTRICAL SUPPLY 100′ 2/0-2/0-2/0-1 SER Cable
The 100-foot version provides extended reach for lengthy service runs or installations with difficult routing. With the same 2/0-2/0-2/0-1 conductor arrangement and four conductors, it delivers reliable performance for 150 amp service upgrades, while the extra length reduces the need for splicing or intermediate feeds. As with other Nassau products, it is designed for both wet and dry locations and meets standard service entrance cable specifications.
Nassau Electrical Supply 90′ 2/0-2/0-2/0-1 SER Cable
This 90-foot length offers flexibility for mid-to-long service runs. Its 2/0-2/0-2/0-1 conductor pattern ensures adequate power delivery for a 150 amp service with four conductors for hot, neutral, and ground paths. Suitable for use in wet or dry locations, the cable is built to withstand typical outdoor and indoor service conditions while meeting UL and industry standards for service entrance cables.
Buying Guide: Key Purchase Considerations
- Length and routing: Measure the path from the meter to the panel, including any turns, to select an appropriate length. Avoid excessive slack that can complicate installation.
- Conductor configuration: Ensure the 4-conductor arrangement (two hots, one neutral, one ground) aligns with the panel’s requirements and local electrical codes.
- Voltage and temperature ratings: Look for 600 V rating and 90°C insulation to maximize durability in wet or dry environments.
- UL classification: Confirm UL 854 certification or equivalent, ensuring compliance with service entrance cable standards.
- Environmental suitability: Determine if the installation location is wet, dry, or damp and choose cable rated for those conditions.
- Future-proofing: If planning potential expansion, select a longer run or a product with greater flexibility to reduce future repiping or splicing.
- Code compliance: Always verify with local electrical codes or a licensed electrician before purchasing or installing SER cables for 150 amp service.
- Vendor and warranty: Choose reputable brands with clear product specs and warranty terms to ensure reliability over the service life.
When upgrading to a 150 amp service, selecting the right SER cable length and rating is essential for safety and long-term performance.
