The Conversions Tech one-hole copper compression lug terminates 4 AWG conductors to 5/16-inch studs in industrial, commercial, and renewable energy installations. The short barrel design with sight window enables visual verification of conductor insertion, while electro tin-plated seamless copper construction resists oxidation and maintains conductivity. Gray color coding aids phase identification in complex panels and switchgear assemblies.

Equivalent to Burndy YAV/YA series, Panduit LCA/LCB series, and Ilsco CCL-4 type compression lugs. Conversions Tech lugs deliver comparable electrical performance and dimensional compatibility at reduced procurement cost.
FAQ
What crimping tool is required for 4 AWG compression lugs?
Use an industry-standard crimp tool with a die set rated for 4 AWG copper compression terminals. The short barrel design accepts standard hex or indent crimp profiles—verify die compatibility with your specific tool manufacturer.
Is this lug suitable for medium voltage applications?
The 35 kV voltage rating supports medium voltage terminations when properly installed with appropriate insulation and clearances per NEC and local utility standards. Always confirm system voltage requirements against the lug rating.
Does the sight window indicate proper conductor insertion depth?
Yes. The sight window allows visual confirmation that the stripped conductor is fully inserted to the specified 0.562" strip length before crimping. This prevents incomplete terminations that create high-resistance connections.
