FAQ
What crimping tool die is required for this lug?
This lug requires an I-50 die index for proper compression. Always verify your crimping tool manufacturer's die chart before installation to ensure compatible tooling.
Why does this lug have two holes instead of one?
Dual-hole pads provide redundant mechanical fastening and improved current distribution across the termination surface. The 5/8-inch hole spacing accommodates standard busbar or equipment stud configurations for 3/0 AWG applications.
Is the 35 kV rating suitable for medium-voltage applications?
The 35 kV voltage rating supports medium-voltage terminations. Verify that your complete termination assembly—including insulation and spacing—meets applicable NEC and equipment standards for your specific voltage class and environment.
