4/0 Compression Lugs
4/0 AWG is one of the most common conductor sizes on service entrances, feeders, battery banks, generators and welding leads. Conversions Tech stocks 4/0 copper compression lugs in one-hole and two-hole patterns, with standard and long barrels, so you can match the lug to the conductor, the stud and the termination spec in one order. In-stock items ship the same day from Oxnard, CA.
Why choose a 4/0 compression lug from Conversions Tech
- Tin-plated copper. The tin plating helps resist oxidation and corrosion at the barrel and tongue.
- UL Listed and 35kV rated. Each product page lists the full spec table, including temperature rating and ampacity.
- Standard or long barrel. Standard barrels fit most panel and equipment terminations. Long barrels give more crimp length where the spec calls for it.
- One-hole or two-hole. Two-hole lugs resist rotation on bus bars and equipment pads. One-hole lugs fit single-stud terminals.

How to pick the right 4/0 lug
- Confirm the conductor. These lugs are for 4/0 AWG copper conductors. Check the stranding class on the product page.
- Match the stud. Measure the stud or bolt on the equipment. Stock covers 1/4", 5/16", 3/8" and 1/2" studs.
- Choose holes and barrel. Use two-hole where the equipment pad has two holes or where rotation is a concern. Use long barrel where your spec or the AHJ requires it.
- Use the right die. Crimp with the die index shown on the product page. See our compression lug dies and 12-ton crimpers.
