FAQ
What crimping die is required for this lug?
Use die index I-24 per manufacturer specification. Verify proper die selection with your compression tool manufacturer to ensure full barrel compression without over-crimping.
Is this lug rated for 90°C conductor ampacity?
Yes. The 90°C temperature rating matches standard THHN/THWN-2 and XHHW-2 conductor ratings. Size conductors per NEC ampacity tables at 75°C or 90°C as applicable for your installation conditions.
Why two holes instead of one?
Dual #10 bolt holes distribute mechanical stress and resist loosening under thermal cycling or vibration. The 5/8" spacing fits standard busbar or equipment terminal patterns. Both bolts must be torqued to manufacturer specification.
