FAQ
What crimping tool is required for this 4 AWG compression lug?
Use a UL-listed compression tool with the appropriate die set for 4 AWG copper terminals. The sight window confirms full conductor insertion before crimping.
Is this lug rated for 90°C conductor ampacity?
Yes. The 90°C temperature rating supports full 4 AWG ampacity per NEC Table 310.16 when used with 90°C rated conductors and proper installation practices.
Can this lug be used in medium voltage applications?
The 35 kV voltage rating suits this lug for medium voltage terminations up to 35 kV. Verify clearances, insulation, and application-specific requirements for your installation.
