FairySandy 50′ SER Aluminum Service Entrance Cable
Configuration: 4/0-4/0-4/0-2/0 aluminum with one 2/0 ground. Length: 25 feet. Rating: 600V, 90°C. Construction emphasizes wet and dry environment suitability. Features lead-free, weather-resistant aluminum with a protective outer skin to reduce fraying. Suitable as an above-ground service cable, switchboard feeder, and branch circuit. Best for: Mobile homes and residential service entrances where longer runs and robust weather resistance are needed. Limitation: Not a copper conductor; performance depends on aluminum properties and ambient conditions.
Why selected: This SER (SE type R) cable is designed for service entrances and distribution access with a clear four-conductor arrangement, meeting common mobile home and residential feeder needs. The weather-resistant design supports outdoor installations and reduced splicing risk in exposed environments.
Copkim 100′ 4/0-4/0-2/0-4 Aluminum Mobile Home Feeder Cable
Configuration: 4/0-4/0-2/0-4 with one 4 AWG ground. Construction uses AA-8000 series compact stranded aluminum conductors for lightweight flexibility. Voltage rating: 600V. Purpose: Primary feeder for mobile homes with clear separation of live, neutral, and ground conductors. Best for: Professionals installing or upgrading 200 Amp service in manufactured homes. Limitation: Aluminum conductors may require careful handling to avoid nicks and bending fatigue during installation.
Why selected: The exact conductor layout ensures proper isolation and safety for mobile home service feeders while offering a balance of weight and durability. It is a practical choice for above-ground or direct burial configurations when permitted by code.
Geosiry 4/0 Battery Cable, Red + Black
Configuration: Red and Black 4/0 + 4/0 pair, 10 ft each. Material: 100% fully annealed oxygen-free copper with EPDM insulation. Rating: 600V, temperature range -122°F to +221°F. Features include high flexibility and resistance to solvents. Best for: Automotive, battery, solar, marine, and generator applications requiring high-conductivity copper. Limitation: Copper cables may be less forgiving in rugged outdoor deployments compared to certain robust aluminum alternatives.
Why selected: The pure OFC copper and heavy duty construction deliver strong current-carrying capacity with excellent conductivity for critical power connections. The dual color pairing helps with clear polarity identification in complex installations.
Shirbly 4/0 Gauge Battery Cable, Red + Black
Configuration: 10 ft each of red and black 4/0 AWG copper wire. Material: Fully annealed OFC with EPDM insulation. Rating: 600V; temperature range -58°F to +221°F. Features solvent resistance and flexibility for outdoor and marine uses. Best for: Automotive, battery, solar, and generator connections that demand durable copper conductors. Limitation: Like other copper cables, heavier gauge copper can be less economical for very long runs compared to high-quality aluminum options.
Why selected: This product offers a robust copper solution with strong insulation and bendability, suitable for high-current battery and electrical system connections where copper’s conductivity advantages matter.
Buying Guide
What configuration fits your project?
Identify whether you need a four-conductor setup with three live conductors and one ground, or a copper-based pair with red/black leads. For mobile homes, SER or dedicated feeder cables with defined ground are essential for safety and code compliance.
Material choice: Aluminum vs Copper
Aluminum cables are lighter and typically more cost-effective for long runs and service feeders. Copper cables offer superior conductivity and durability in harsh environments but are heavier and more expensive. Choose based on distance, current load, and installation conditions.
Voltage and temperature ratings
Most 4/0 cables listed here are rated around 600V and 90°C or higher. Confirm the operating temperature range matches your environment, especially in outdoor installations or areas prone to temperature fluctuations.
Environment and protection
Consider whether the installation will be exposed to moisture, UV exposure, or direct burial. For outdoor or underground use, ensure the insulation and jacket material provide adequate moisture and chemical resistance.
Installation considerations
Pay attention to conductor type, insulation, and grounding configuration. Follow local electrical codes and use appropriately rated connectors, clamps, and protection to minimize wear and movement.
