FAQ
What crimping tool is required for 4/0 AWG compression lugs?
Use an industry-standard hydraulic crimping tool with dies sized for 4/0 AWG copper compression terminals. Verify die compatibility with the specific lug barrel dimensions before crimping.
Is this lug suitable for 90°C wet locations?
The 90°C temperature rating applies to the lug material. Installation location suitability depends on the complete termination assembly and enclosure ratings. Verify against NEC requirements for your specific application.
Can I use this lug for aluminum conductors?
No. This lug is specified for copper conductors only. Aluminum conductors require lugs rated for aluminum or dual-rated copper/aluminum with appropriate antioxidant compound.
