The Long Barrel One-Hole Compression Lug terminates 250 MCM copper conductors in high-current industrial and commercial electrical systems. The long barrel construction accommodates multiple crimps for enhanced mechanical retention and electrical contact. Designed for termination to bus bars, switchgear, and heavy equipment with 7/8-inch studs.
Manufactured from seamless electro-tin plated copper with a chamfered barrel entry for conductor insertion. The bright yellow color code provides visual identification per industry standards.

FAQ
What crimp pattern is required for the long barrel?
The 1.688-inch barrel length supports multiple crimps. Use a compression tool with dies rated for 250 MCM copper and follow the tool manufacturer's recommended crimp pattern—typically two or more indent crimps distributed along the barrel length.
Is this lug rated for aluminum conductors?
No. This lug is engineered for 250 MCM copper conductors only. Aluminum conductors require lugs with compatible metallurgy and oxide-inhibiting compounds.
Does the 35 kV rating apply to all installations?
The 35 kV rating applies when the lug is installed with proper clearances, insulation, and in accordance with applicable electrical codes. System voltage, insulation coordination, and environmental conditions must be evaluated for each application.
