FAQ
What crimping tool is required for this 4 AWG compression lug?
Use a compression tool with a die set rated for 4 AWG copper lugs. The standard barrel design requires proper die selection to achieve the specified compression force without over-crimping. Verify tool compatibility with UL 486A/B requirements.
Is this lug suitable for 90°C rated conductors?
Yes. The 90°C temperature rating matches standard THHN/THWN-2 and XHHW-2 insulated conductors. Do not exceed 125A continuous current per the maximum ampacity rating.
Can the sight window confirm full conductor insertion?
Yes. The sight window provides visual verification that the conductor is fully seated to the proper depth before compression. This reduces installation errors and rework in field conditions.
