FAQs
Q1: What is the significance of the “Long Barrel” design on this lug?
The long barrel (0.7 inches) provides a greater surface area for the crimp, which significantly enhances the connection’s mechanical strength, improves heat dissipation, and reduces resistance, resulting in a more robust and reliable connection, especially in high-vibration applications.
Q2: What does “NEBS Level 3” certification mean for this product?
NEBS (Network Equipment-Building System) Level 3 certification indicates that this lug has been rigorously tested for reliability in critical environments, including seismic tolerance, temperature extremes, and fire resistance. It is essential for telecommunications and data center installations.
Q3: How does the installation process differ from a standard barrel lug?
Due to the long barrel, the required wire strip length is longer: 3/4 inch (19.1 mm). This extended strip length ensures the conductor fills the entire barrel for maximum crimp integrity.
Q4: Is there an inspection window on this model?
No, this specific model features a fully enclosed long barrel design without an inspection window. Proper installation relies on using the specified 3/4 inch (19.1 mm) strip length and the correct crimping die (P21 / 49T / 21).
