Product Features & Engineering Logic
| Key Area | Feature | Advantage | Benefit |
| Connection Security | Long Barrel Design (1.16 in / 29.5 mm) with 1-1/4 in (31.8 mm) strip length. | Provides a large crimp area, maximizing contact and strain relief for the terminated 2 AWG conductor. | Maximized Pull-Out Strength: Ensures a permanent, robust connection that withstands high mechanical stress and vibration. |
| Critical Reliability | UL/CSA Certified and NEBS Level 3 Compliance (No inspection window). | Engineered for the most demanding environments where equipment must resist shock, vibration, and temperature extremes. | Assured Uptime: Guarantees certified performance in mission-critical applications like telecommunications and utility infrastructure. |
| Mounting Versatility | Single 5/16 inch (7.9 mm) stud hole configuration. | Allows for versatile, compact termination on smaller terminal blocks, single-point grounding applications, and equipment with limited mounting space. | Simplified Routing: Ideal for applications requiring quick, flexible cable routing and single-point attachment. |
| Precision Installation | Standardized Brown Color Code (P33 / 10 / 33 die indices). | Ensures the installer uses the correct crimp die required for certified installation of 2 AWG copper lugs. | Code Compliance: Guarantees the necessary compression force is applied for a permanent, low-resistance termination. |
FAQs
Q1: How do I ensure proper wire seating since this model has no inspection window?
Since there is no inspection window, accurate wire preparation is crucial. The 2 AWG wire must be stripped precisely to the specified length of 1-1/4 inches (31.8 mm). The solid barrel design ensures maximum conductor containment and gas-tight integrity once the correct crimp is applied.
Q2: What is the benefit of the 5/16 inch stud hole size?
The 5/16 inch (7.9 mm) stud hole is a heavy-duty size, offering a higher torque capability than a 1/4 inch hole. This is beneficial in industrial applications where secure, high-force bolting is necessary to prevent loosening under vibration.
Q3: Can this single-hole lug be used in environments requiring NEBS certification?
Yes. This lug is explicitly rated for NEBS Level 3 compliance, making it suitable for high-reliability network equipment and telecommunications applications where resistance to vibration, shock, and temperature variations is mandatory.
Q4: Which crimp tool color code corresponds to this 2 AWG single-hole lug?
The required crimp tool die index is identified by the Brown color code, corresponding to Panduit P33, Burndy 10, and T&B 33 indices. Always match the die index to the color code for a certified connection.
