SER Service Entrance Cable
Farwalk’s SER (Service Entrance Round) cables are the versatile solution for secondary voltage distribution. Specifically engineered with high-conductivity AA-8000 series aluminum alloy, these cables are designed for use as service entrance conductors and interior branch circuits, providing a cost-effective alternative to copper without compromising on safety or building code compliance.
Manufactured in strict accordance with UL Standard 854. The assembly consists of two, three, or four phase conductors and a neutral conductor. The phase conductors are insulated with heat and moisture-resistant Cross-linked Polyethylene (XLPE). The reinforced core is jacketed with a sunlight-resistant, lead-free PVC outer sheath. All conductors utilize premium AA-8000 series aluminum alloy.
Primarily used as a service entrance conductor from the meter base to the main distribution panel, and as a sub-feeder from the main panel to sub-panels. It is rated for use in residential, commercial, and industrial buildings as defined by the National Electrical Code (NEC). Approved for indoor use and outdoor installations where sunlight resistance is required.
• Voltage Rating: 600V
• Conductor: AA-8000 Series Aluminum Alloy
• Insulation: XLPE (Type XHHW-2)
• Outer Jacket: Sunlight-Resistant PVC
• Temp. Rating: 90°C Dry/Wet
1. Phase Conductors: Class B stranded aluminum alloy (8000 series) or copper.
2. Neutral Conductor: Insulated or bare, depending on configuration.
3. Insulation: Cross-linked Polyethylene (XLPE), moisture and heat resistant.
4. Reinforcement: A clear or polyester binder tape may be applied over the core assembly.
5. Outer Sheath: Sunlight-resistant, moisture-resistant PVC (Polyvinyl Chloride), typically grey or black.
• Comprehensive Assembly: Combines phase, neutral, and ground conductors under one durable jacket, simplifying complex multi-run residential service installations.
• Superior XLPE Insulation: Rated for 90°C in both dry and wet locations, preventing thermal deformation and ensuring a long service life.
• Ease of Installation: Farwalk’s SER cables are engineered for high flexibility compared to rigid conduits, allowing for faster routing through floor joists and wall studs.
• 8000 Series Aluminum Performance: We utilize premium AA-8000 series aluminum alloy conductors, which provide the optimal balance of conductivity, weight savings, and resistance to creep/corrosion.
• Strictly UL 854 Compliant: Manufactured and tested to exceed UL 854 standards, ensuring every roll passes local building code inspections without friction.
• Contractor-Focused Design: Our PVC jacket is specifically formulated for low-friction pulling, reducing physical strain during residential service entries.
