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 optimal surface area for crimping, creating a low-resistance, gas-tight electrical joint and superior mechanical holding force. | Maximized Durability: Ensures the connection resists high vibration, thermal cycling, and maximizes overall pull-out strength. |
| Heavy-Duty Mounting | Single 3/8 inch (9.5 mm) stud hole configuration. | Accommodates larger mounting hardware, allowing for higher torque application during installation. | Reliable Stability: Ideal for industrial, automotive, and heavy-duty applications where secure bolting prevents loosening and potential failure. |
| Critical Environment Ready | UL/CSA Certified and NEBS Level 3 Compliance. | Meets the stringent requirements for reliability, shock, and vibration resistance in mission-critical installations. | Operational Assurance: Guarantees certified performance in demanding environments like telecommunications centers and power distribution facilities. |
| Precision Installation | Beveled barrel entry and standardized Brown Color Code (P33 / 10 / 33 die indices). | Simplifies conductor insertion and ensures the installer selects the exact crimp die required for a fully certified termination. | Consistent Quality: Reduces labor time and guarantees the connection meets the necessary compression specifications for safety and longevity. |
FAQs
Q1: Since this lug has no inspection window, how do I ensure the wire is inserted correctly?
Proper installation relies on precise wire preparation. The 2 AWG wire must be stripped exactly to the specified length of 1-1/4 inches (31.8 mm). The long barrel design ensures the conductor fully bottoms out, achieving a solid internal stop for certified crimping.
Q2: Why choose the 3/8 inch stud size for 2 AWG?
The 3/8 inch stud size provides a larger cross-sectional area for the bolt connection, which is crucial for applications demanding higher mechanical strength and torque. This is often preferred in heavy electrical panels or systems subject to greater mechanical stress.
Q3: Is this lug rated for high-voltage use?
Yes, this lug is UL Listed and rated for applications up to 35 kV. This high rating confirms its superior insulation and electrical integrity, making it safe for use across low, medium, and high-voltage systems.
Q4: Which crimping tool color code and die set should be used with this product?
The lug features a Brown color code, indicating the use of Panduit die index P33, Burndy index 10, or T&B index 33. Matching the die index to the color code is essential for a UL-compliant, permanent connection.
