The Conversions Tech short barrel one-hole compression lug terminates 4 AWG copper conductors in industrial panels, commercial distribution equipment, and switchgear. The single-hole design with 3/8-inch bolt mounting provides a secure mechanical connection while the sight window allows visual confirmation of full conductor insertion before compression. Tin-plated copper construction resists oxidation and maintains conductivity over the service life of the installation.

FAQ
What crimping tool and die size are required for this lug?
Use an industry-standard compression tool with dies appropriate for short barrel lugs on 4 AWG copper. The sight window confirms proper die placement before compression.
Is this lug rated for 90°C conductor applications?
Yes. The 90°C temperature rating matches THHN/THWN-2 and XHHW-2 conductors at 75°C ampacity or higher when used with 90°C rated wire.
Can this lug be used in medium voltage terminations?
The 35 kV voltage rating supports medium voltage applications. Follow applicable termination kits and clearances per IEEE 404 and manufacturer instructions for the specific cable and equipment.
