FAQ
What crimping tool and die should I use with this lug?
This lug requires die index I-29 for proper compression. Verify your crimping tool manufacturer's die chart to confirm compatibility with I-29 dies. Proper die selection ensures full barrel compression and maintains the 35 kV voltage rating.
Is this lug suitable for 90°C conductor applications?
Yes. The lug is rated for 90°C continuous operation when used with appropriately rated 4 AWG copper conductors. This temperature rating supports standard industrial and commercial applications including switchgear terminations and power distribution equipment.
Does the 1-inch hole spacing match standard busbar drilling patterns?
Yes. The 1-inch pad hole spacing aligns with common NEMA-standard busbar and terminal block configurations. Verify your specific equipment dimensions before installation, as hole spacing must match existing studs or bolts for proper fit.
