The Conversions Tech Copper Long Barrel Two-Hole Compression Lug is engineered for high-current electrical terminations using 3/0 AWG conductors. This tin-plated copper lug features a long barrel design with dual mounting holes on a 5/8-inch spacing, providing secure mechanical and electrical connections for switchgear, transformers, panelboards, and power distribution equipment. The orange color code enables quick wire size identification in crowded termination cabinets.

FAQ

What crimping tool die is required for this lug?

This lug requires an I-50 die index for proper compression. Always verify your crimping tool manufacturer's die chart before installation to ensure compatible tooling.

Why does this lug have two holes instead of one?

Dual-hole pads provide redundant mechanical fastening and improved current distribution across the termination surface. The 5/8-inch hole spacing accommodates standard busbar or equipment stud configurations for 3/0 AWG applications.

Is the 35 kV rating suitable for medium-voltage applications?

The 35 kV voltage rating supports medium-voltage terminations. Verify that your complete termination assembly—including insulation and spacing—meets applicable NEC and equipment standards for your specific voltage class and environment.
