FAQs (Click to Expand)
1. What conductor size does this lug support?
This compression lug fits 1/0 AWG copper conductors and ensures a precise mechanical and electrical connection.
2. Why use a dual-hole lug?
Dual-hole lugs provide greater mechanical strength and distribute torque evenly, preventing rotation and maintaining a tight connection.
3. What does the pink color code indicate?
Pink identifies compatibility with 1/0 AWG wire under the standard color-coded compression-lug system.
4. What crimping die should I use?
Use a compression tool calibrated for 1/0 AWG copper lugs. Follow die markings that correspond to pink color or manufacturer die index for accurate compression.
5. Can I use this lug in outdoor environments?
Yes. The tin-plated copper finish resists corrosion and oxidation, making it ideal for outdoor, marine, and industrial applications.
6. What is its voltage rating?
This lug is rated for operation up to 35 kV, suitable for medium- and high-voltage circuits.
7. What is the maximum current capacity?
It supports loads up to 230 amps depending on installation conditions and conductor specifications.
8. Does it meet certification standards?
Yes, it’s UL Recognized, CE Certified, and RoHS Compliant, ensuring compliance with international safety requirements.
9. How do I prepare the conductor before crimping?
Strip insulation cleanly, brush away oxidation, insert the conductor fully into the barrel, and crimp firmly using the proper die for a gas-tight connection.
10. Can this lug be used for both AC and DC applications?
Yes. The 1/0 AWG lug is rated for both AC and DC systems, including renewable-energy and backup-power installations up to 35 kV.
