The Conversions Tech 2-Hole Copper Compression Lug is a short-barrel terminal connector engineered for 3 AWG conductors in industrial electrical installations. Designed for switchgear, panelboards, motor control centers, and transformer terminations, this lug provides secure two-bolt mounting with visual confirmation of proper conductor insertion through the integrated sight window. The tin-plated copper construction delivers reliable conductivity with corrosion resistance for long-term service in commercial and industrial power distribution systems.

FAQ
What crimping tool and die are required for this 3 AWG lug?
Use a standard compression tool with a die set matched to short-barrel copper lugs for 3 AWG conductors. The chamfered barrel entry accommodates standard industry crimpers. Verify die index alignment with the sight window to confirm full conductor insertion before crimping.
Does the 35 kV rating apply to all installation conditions?
The 35 kV rating applies to the lug's insulation withstand capability when properly installed with compatible insulation systems. For medium-voltage applications above 600V, follow NEC Article 310 and manufacturer installation instructions for clearances, insulation, and termination methods appropriate to the system voltage class.
Why does this lug have two holes instead of one?
The two-hole pad design distributes mechanical and electrical load across two mounting points, reducing stress on individual bolts and providing redundant contact in high-vibration environments such as generator terminations, switchgear lineups, and heavy industrial equipment. The 1-3/4" hole spacing matches standard busbar drilling patterns.
