The Conversions Tech two-hole copper compression lug terminates 3 AWG conductors in industrial power distribution, switchgear, and panelboard applications. The short barrel design with chamfered entry accommodates standard compression tooling, while the dual-hole pad provides mechanical redundancy for high-vibration environments. A sight window enables visual verification of conductor insertion depth prior to crimping.

FAQ
What compression die set is required for this lug?
Use standard compression tooling sized for 3 AWG copper lugs. The chamfered barrel entry accommodates standard industry dies; verify die index marks with your specific tool manufacturer's chart.
Is this lug suitable for outdoor or wet location use?
The tin-plated copper construction provides corrosion resistance. For specific environmental ratings, consult your local electrical inspector regarding tape and sealant requirements for your application conditions.
Why does the pad show 1-3/4" spacing but the table shows 10.4mm?
The 1-3/4" (44.5mm) dimension refers to center-to-center spacing between the two 3/8" mounting holes on the pad. The 10.4mm dimension in the table refers to a different measurement point on the lug geometry. Always use the 1-3/4" spacing for busbar and terminal planning.
