The Conversions Tech long barrel two-hole compression lug terminates 3 AWG conductors to busbars or equipment terminals. The extended barrel length provides additional crimp surface area for mechanical stability in high-vibration environments. Dual 1/4-inch mounting holes on 0.28" centers allow secure two-bolt attachment to prevent rotation under fault current conditions. Tin-plated copper construction resists oxidation while maintaining conductivity. White color coding per industry standards enables quick wire-size identification during installation and inspection. Typical applications include switchgear terminations, motor control centers, power distribution blocks, and transformer connections.

FAQ
What crimp die should be used for this lug?
Use a crimp tool and die set specified for 3 AWG copper compression lugs. The long barrel requires full-length crimping along the conductor insertion area—consult your crimp tool manufacturer's die chart for the correct color code or die index that accommodates 14.5mm barrel diameter.
Is this lug rated for 90°C wire?
Yes. The 90°C temperature rating permits use with 90°C insulated conductors per NEC ampacity tables. When installed in equipment with lower temperature limitations, the lowest rating applies.
Why use a two-hole lug instead of single-hole?
Two-hole mounting prevents lug rotation under short-circuit forces or thermal cycling, maintaining bolt torque and electrical contact integrity. Required by some specifications for busbar connections in switchgear and substation applications.
