The Conversions Tech 4 AWG Copper Compression Lug is a short-barrel, single-hole terminal designed for secure termination of 4 AWG copper conductors in power distribution panels, industrial machinery, and electrical enclosures. The tin-plated copper construction provides corrosion resistance and maintains conductivity, while the integrated sight window allows visual confirmation of proper wire insertion during crimping.

FAQ
What crimping tool is required for this 4 AWG compression lug?
Use a UL-listed compression tool with the appropriate die set for 4 AWG copper terminals. The sight window confirms full conductor insertion before crimping.
Is this lug rated for 90°C conductor ampacity?
Yes. The 90°C temperature rating supports full 4 AWG ampacity per NEC Table 310.16 when used with 90°C rated conductors and proper installation practices.
Can this lug be used in medium voltage applications?
The 35 kV voltage rating suits this lug for medium voltage terminations up to 35 kV. Verify clearances, insulation, and application-specific requirements for your installation.
