FAQ
What crimping tool and die are required for this lug?
This lug requires an I-66 die index for proper compression. Verify your crimping tool manufacturer's die chart to confirm compatibility with the I-66 index for 300 MCM copper compression terminals.
Is this lug suitable for outdoor or wet location applications?
The electro-tin plated finish provides corrosion resistance. For specific environmental ratings and appropriate sealing methods, consult applicable NEC or local code requirements for your installation conditions.
How do I confirm proper conductor insertion before crimping?
The lug includes a sight hole (sight window) that allows visual confirmation that the conductor is fully inserted to the correct depth prior to compression. Strip length should be 1.125 inches for proper seating.
