Product Features & Engineering Logic
| Key Area | Feature | Advantage | Benefit |
| Connection Integrity | Long Barrel Design (0.7 in / 17.8 mm) with 3/4 in (19.1 mm) strip length. | Maximizes the surface area for the crimp, creating a low-resistance and highly secure mechanical joint. | Superior Reliability: Provides maximum pull-out strength and improved thermal performance under continuous load. |
| Universal Flexibility | Approved for all 8 AWG flexible copper cable classes (G, H, I, K, M, DLO). | Guarantees compatibility across diverse applications, including motor leads, battery banks, and heavy mobile equipment. | Streamlined Inventory: Eliminates the need for specialized lugs, ensuring one component meets the needs of various flexible conductor types. |
| Installation Accuracy | Includes a visible inspection window and uses a clear Red Color Code. | Allows installers to verify the conductor is fully seated and ensures the correct crimp die (P21 / 49T / 21) is selected. | Error-Free Termination: Reduces the risk of faults caused by incomplete insertion or incorrect tooling, saving time and costs. |
| Standard Mounting | Single 1/4 inch (6.4 mm) stud hole configuration. | Fits standard terminal blocks, relays, and power supply posts requiring a single-point connection. | Easy Integration: Allows for quick, reliable mounting using common hardware in most electrical systems. |
FAQs
Q1: Is this lug compatible with all types of flexible 8 AWG cable?
Yes. This lug is fully approved for the termination of all major flexible copper cable classes, including Class G, H, I, K, M, and DLO (Diesel Locomotive Cable), ensuring compatibility across virtually any mobile or high-flex application.
Q2: What is the correct wire strip length for this lug?
The 8 AWG conductor must be stripped precisely to 3/4 inch (19.1 mm). The installer can then use the inspection window to visually confirm the conductor is fully seated in the long barrel before proceeding with the crimp.
Q3: How do I select the right crimping tool?
The required crimp tool die index corresponds to the Red color code on the lug. Use a certified crimping tool set to Panduit P21, Burndy 49T, or T&B 21 to achieve a UL/CSA approved gas-tight connection.
Q4: Can this 35 kV rated lug be used in low-voltage applications?
Yes. A 35 kV rating indicates the maximum voltage capability. The lug can be safely and reliably used in all low and medium voltage applications, offering a high safety margin and robust insulation piercing strength.
