FAQ
What crimping tool and die are required for this lug?
Use a compression tool with a die set matched to 4/0 AWG long-barrel terminals. The extended barrel requires full-length crimping; follow the manufacturer's crimp pattern for two-hole long-barrel configurations to achieve listed ampacity.
Is this lug suitable for medium-voltage applications?
The 35 kV voltage rating supports medium-voltage terminations when installed per applicable codes. Verify insulation clearances and shielding requirements for your specific MV cable and application.
Why does this lug have two holes?
Dual-hole mounting provides mechanical redundancy and distributes torque across two bolts, reducing loosening from vibration in industrial and utility environments. The 13.0mm hole spacing matches standard busbar drilling patterns.
