FAQ
What crimp tool and die are required for this lug?
Use a compression tool with die index I-29. Verify proper crimp placement using the barrel length specification (1.125 inches) to ensure full compression over the conductor.
Is this lug rated for the conductor insulation size?
The insulation ID/OD of 0.25 in x 0.343 in indicates compatible insulation diameters. Verify your conductor insulation falls within this range for proper fit.
Can this lug be used in 35 kV applications?
The 35 kV voltage rating applies to the lug construction. Actual system voltage capability depends on complete installation geometry, clearances, and insulation coordination per applicable codes.
