Goes with
The 4/0 AWG One-Hole Copper Compression Lug is a standard-barrel terminal connector designed for high-current power distribution terminations.The tin-plated copper construction delivers corrosion resistance while maintaining conductivity, and the integrated sight window enables visual verification of proper wire insertion prior to crimping. The purple color code identifies the conductor size for quick field identification.

FAQ
What crimping tool is required for 4/0 AWG compression lugs?
Use a hydraulic crimping tool with dies rated for 4/0 AWG copper compression terminals. The sight window confirms full conductor insertion before crimping. Follow the tool manufacturer's die chart for the specific lug barrel dimensions.
Is this lug suitable for 90°C conductor applications?
Yes. This lug is rated for 90°C continuous operation and supports 360A maximum ampacity when used with appropriately sized 4/0 AWG 90°C conductors per NEC ampacity tables.
Can this lug be used in 35kV medium-voltage applications?
The 35kV voltage rating applies to the lug's insulation withstand capability when properly installed with compatible stress-relief and insulation systems. Verify complete system compatibility with your application engineer for medium-voltage installations.
