The Conversions Tech 1-Hole Copper Compression Lug is a short-barrel compression terminal designed for 1 AWG conductors in industrial and commercial electrical installations. This lug provides a secure mechanical and electrical connection when properly crimped, suitable for use in switchgear, panelboards, motor control centers, and power distribution equipment. The tin-plated copper construction resists oxidation, while the integrated sight window allows visual confirmation of full conductor insertion before crimping. The green color code provides quick wire size identification during installation and inspection.

Cross-Reference
This 1 AWG short-barrel compression lug with 5/16" stud hole is equivalent in form and function to standard one-hole copper lugs offered by major manufacturers including Burndy, Panduit, and Ilsco. Conversions Tech lugs are engineered to US specifications and manufactured to consistent dimensional tolerances for reliable crimping with industry-standard tooling.
FAQ
What crimping tool is required for this 1 AWG compression lug?
Use a compression tool with a die set rated for 1 AWG copper lugs. The short barrel design requires proper die selection to achieve the manufacturer-specified crimp profile. Verify the crimp is complete using the sight window to confirm full conductor insertion.
Is this lug suitable for 90°C rated conductors?
Yes. The lug is rated for 90°C continuous operation when used with 90°C insulated conductors sized per NEC ampacity tables. The 130A maximum rating applies under standard conditions; derating may be required for elevated ambient temperatures or bundled conductor installations.
Can this lug be used in medium voltage applications?
The 35 kV voltage rating supports use in medium voltage terminations up to 35,000 volts when installed with appropriate insulation and stress relief components per the equipment manufacturer's instructions. Always verify system voltage and application requirements before installation.
