The Conversions Tech 250 MCM Copper Compression Lug is a long-barrel, single-hole terminal designed for high-current power distribution applications. Engineered for 250 MCM copper conductors, this lug features a 5/16-inch stud hole and extended barrel length to accommodate multiple crimp points for maximum mechanical retention and electrical conductivity. The seamless electro-tin plated copper construction provides corrosion resistance for industrial panels, utility installations, renewable energy systems, and grounding applications.

FAQ
What crimp die should I use with this lug?
This lug references Die Index I-42. Use a crimp tool rated for 250 MCM copper compression lugs with the appropriate die set to ensure proper compression and electrical contact.
Is this lug rated for outdoor or wet location use?
The electro-tin plated copper construction provides corrosion resistance. The 35 kV voltage rating and 90°C temperature rating support demanding environments. Verify specific installation requirements against local codes and application conditions.
Why choose a long barrel over a standard barrel lug?
The 1.5-inch barrel length allows multiple crimp positions, increasing pull-out strength and reducing resistance compared to short-barrel designs. This improves long-term reliability in high-vibration or high-current applications.
