4/0 AWG FLEX Copper Lug – Two Hole 3/8″ 1″ Spacing Purple Die 54 – XLUIG

PRODUCT PARAMETERS

  • Optimized for FLEX Cables: Specially engineered flared barrel entry for easy insertion of high-strand, flexible copper conductors without strand damage.

  • Two-Hole Non-Rotational Stability: Dual 3/8" stud holes with standard 1" spacing ensure a secure, anti-twist connection for industrial busbars.

  • 99.9% High-Purity T2 Copper: Provides maximum electrical conductivity and superior performance for high-amperage power distribution.

  • Purple Color Coded (Die Index 54): Standardized visual identification for 4/0 AWG ensures precise matching with the correct crimping die.

  • Integrated Inspection Window: Enables quick visual confirmation that the 4/0 FLEX cable is fully and properly seated before crimping.

  • Anti-Corrosive Electro-Tin Finish: Premium tin plating protects the terminal against oxidation and environmental corrosion in harsh settings.

Product Features & Engineering Logic

Engineering ExcellenceOperational AdvantagesProfessional Business Value
Flared Barrel Entry for FLEXSpecifically accommodates the wider diameter of high-strand “Flex” cables, preventing strand “birdcaging” during insertion.Reduced Labor Costs: Speeds up the termination process for complex, flexible wiring systems and eliminates rework.
Two-Hole 1.0″ Spacing DesignDistributes mechanical load across two bolts, preventing the terminal from loosening due to cable weight or vibration.System Security: Maintains a permanent, low-resistance grounding or power path, reducing the risk of arc-flashes in critical panels.
Heavy-Duty Seamless T2 CopperOne-piece seamless construction prevents the barrel from splitting under the high pressure of hydraulic crimping tools.Long-Term ROI: Guaranteed structural integrity and electrical efficiency, extending the lifespan of your power infrastructure.
Purple/54 Visual ID SystemProvides an unmistakable visual cue for installers to select the correct 4/0 AWG wire and matching Die Index 54.Zero Error Installation: Simplifies quality control and ensures every connection meets UL and safety standards without guesswork.

FAQs

Q: Why is a “FLEX” lug required for high-strand copper cables?

A: Flexible cables (FLEX) have a much higher strand count and a slightly larger outer diameter than standard rigid cables. XLUIG FLEX lugs feature a flared barrel entry that allows these fine strands to slide in smoothly without snagging or “birdcaging,” ensuring 100% of the copper is captured for a safe connection.

Q: What is the benefit of the two-hole design with 1″ spacing?

A: The two-hole configuration is designed for non-rotational stability. With 1″ spacing (a standard NEMA configuration), the lug is secured by two 3/8″ bolts, preventing it from twisting or loosening during installation or when subjected to heavy vibrations in industrial machinery.

Q: What crimping tool and die should be used for this Purple lug?

A: All XLUIG 4/0 AWG FLEX terminals are color-coded Purple and require a Die Index 54. Using the correct die ensures a professional, gas-tight compression that meets industrial safety standards for high-current applications.
