FAQs (Click to Expand)
1. What conductor size does this lug support?
This model is precisely sized for 4/0 AWG copper conductors, providing a tight mechanical and electrical connection.
2. Why choose a dual-hole compression lug?
Dual holes distribute torque evenly, prevent rotation during tightening, and provide vibration resistance in high-load installations.
3. What does the purple color code mean?
Purple identifies compatibility with 4/0 AWG wire under the standard color-coded compression-lug system.
4. Is this lug suitable for outdoor use?
Yes. The tin-plated copper body resists corrosion, oxidation, and galvanic wear in outdoor or marine environments.
5. What crimping die should I use?
Use a compression tool with the manufacturer-recommended die index for 4/0 AWG lugs to ensure a UL-approved crimp and gas-tight seal.
6. What is the rated current capacity?
The lug supports up to 230 A, depending on installation conditions and conductor type.
7. What voltage rating does it carry?
It’s rated for electrical systems up to 35 kV, suitable for medium- and high-voltage power circuits.
8. Does this lug meet certification standards?
Yes. It is UL Recognized, CE Certified, and RoHS Compliant, ensuring full safety and quality compliance.
9. How should I prep the wire before crimping?
Clean and strip the conductor, insert it fully into the barrel, and crimp using the correct die pressure for a solid, low-resistance termination.
10. Can it be used for both AC and DC circuits?
Yes. The 4/0 AWG copper lug is rated for AC and DC systems, including solar, battery, and industrial applications up to 35 kV.
