FAQ
What crimping tool and die are required for this lug?
This lug requires the I-76 die index for proper compression. Use a hydraulic crimping tool rated for 400 MCM copper lugs. The chamfered barrel entry facilitates conductor insertion, and the sight window allows visual confirmation of full insertion depth before crimping.
Is this lug rated for 90°C conductor ampacity?
Yes. The 90°C temperature rating permits full use of 90°C ampacity tables per NEC, provided the connected equipment and conductors are similarly rated. The tin-plated copper construction maintains stable contact resistance across this temperature range.
Can this lug be used in 35 kV medium-voltage applications?
The 35 kV voltage rating indicates dielectric withstand capability. Verify application suitability with your engineering specifications, as medium-voltage installations require proper clearances, insulation, and termination kits beyond the lug rating itself.
