The Conversions Tech long barrel two-hole compression lug terminates 3/0 AWG copper conductors in medium-voltage distribution, switchgear, and transformer applications. The extended barrel design maximizes contact surface area for high-current reliability, while the dual-hole pad configuration distributes mechanical load across two 1/2-inch studs. Orange color coding provides immediate wire size identification in crowded termination boxes. The chamfered cable entry and seamless electro-tin-plated copper construction resist corrosion and accommodate heavy-wall insulation without nicking.

FAQ
What crimping tool is required for this lug?
Use a compression tool with I-50 die index. Verify die compatibility with your tool manufacturer; the long barrel requires full-length crimping to achieve rated ampacity.
Is this lug rated for outdoor or wet location use?
The tin-plated copper construction and 90°C temperature rating suit standard industrial environments. For specific environmental ratings, consult your local electrical code and application requirements.
Can I use this with fine-stranded flexible conductor?
This lug is specified for 3/0 AWG conductors. For fine-stranded or flexible cables, verify conductor diameter against the 0.484" inner barrel diameter and chamfered entry dimensions.
