The Conversions Tech long barrel compression lug is a one-hole copper terminal designed for 4 AWG conductors and 1/2-inch mounting studs. Engineered for industrial power distribution, commercial electrical systems, and utility applications where reliable high-current termination is required. The long barrel construction accommodates multiple crimp zones for enhanced mechanical grip and electrical contact surface area. Seamless electro-tin plated copper construction provides conductivity and corrosion resistance. Gray color coding identifies wire gauge for field verification. Chamfered barrel entry facilitates conductor insertion.

FAQ
What crimping tool is required for this lug?
Use industry-standard compression tools rated for 4 AWG copper lugs with long barrel dies. The long barrel design requires multiple crimps per manufacturer tooling guidelines. Verify die compatibility with your specific crimping equipment.
Is this lug suitable for 35 kV applications?
The lug is rated for 35 kV maximum. Verify complete system insulation coordination and follow NEC/NEMA application standards for medium-voltage installations. Temperature rating is 90°C continuous.
Does the tin plating affect termination torque?
Tin-plated copper maintains standard torque values for copper terminations. Follow equipment manufacturer torque specifications for 1/2" studs. The plating provides corrosion resistance without requiring torque derating.
