The Conversions Tech 2-Hole Copper Compression Lug is a short-barrel connector engineered for 3 AWG conductors in industrial and utility electrical systems. The tin-plated copper construction provides conductivity and corrosion resistance for terminations in switchgear, transformers, panelboards, and power distribution equipment. The two-hole design with 1-3/4 inch pad hole spacing allows secure mounting to dual-terminal configurations, while the integrated sight window enables visual verification of proper conductor insertion during installation.

FAQ
What crimping tool and die are required for 3 AWG compression lugs?
Use a UL-listed compression tool with dies rated for 3 AWG copper. The short barrel design requires proper die alignment; verify tool compatibility with the 14.5mm outer barrel diameter before installation.
Is this lug suitable for medium-voltage applications?
The 35kV voltage rating supports medium-voltage terminations up to 35,000 volts. Verify clearances and insulation requirements per NEC and local utility standards for the specific installation environment.
What does the white color code indicate?
The white color code identifies this lug as rated for 3 AWG conductors per industry standard color-coding systems, enabling quick visual verification in complex wiring configurations.
