What size compression lug do I need?

Match the lug barrel to your conductor AWG and the stud hole to your terminal bolt. Common stud sizes are 1/4 inch, 5/16 inch, 3/8 inch, and 1/2 inch. Use our lug sizing guide at conversionstech.com for the complete AWG-to-stud chart.

What is the difference between compression and mechanical lugs?

Compression lugs use a permanent crimp creating a gas-tight connection with lower resistance and better long-term reliability. Mechanical lugs use set screws allowing removal for maintenance. Compression is preferred for permanent installations.

Are Conversions Tech compression lugs UL listed?

Yes. All Conversions Tech compression lugs carry UL 486A/B listing and meet IEEE 837 pull-out force requirements. They are suitable for power circuit terminations per NEC Article 110.14.
