FAQ
What crimping die do I need for this 300 MCM lug?
This lug requires an I-66 die index for proper compression. Verify your crimping tool compatibility with the I-66 die specification before installation.
Is this lug rated for 90°C conductor ampacity?
Yes, the 90°C temperature rating supports full ampacity per NEC Table 310.16 for 300 MCM copper conductors when installed in equipment rated for 90°C terminations.
Can I use this lug with aluminum conductors?
No, this lug is specified for copper conductors only. The material compatibility, barrel dimensions, and crimp specifications are engineered specifically for 300 MCM copper cable.
