One-Hole Compression Lug for 4 AWG Copper

This copper lug accepts a single 4 AWG stranded copper conductor with a 1/4 inch stud hole. The seamless barrel design and long barrel length provide a reliable crimp termination for power distribution and grounding tasks. It is rated for 600 V AC and a maximum operating temperature of 300 degrees F.

Seamless Barrel Build with Gray Color Code

The seamless construction eliminates a potential split path under high current or vibration. A gray color code and die code 29 identify the correct crimp tool setting for a consistent connection. The straight tongue with a 0.52 inch width fits standard 1/4 inch studs on bus bars or terminal blocks.

CSA and UL Listed for Code-Compliant Work

This lug carries both CSA certification and UL listing, meeting requirements for electrical inspections in commercial and residential installations. It replaces older two-hole lugs where only a single mounting point is available or where panel space is limited. The jump is worth it when a seamless, inspected crimp is specified over a mechanical set-screw connector.

Questions about this item

What does the 600 V AC rating cap in practice?

The lug is UL Listed and CSA Certified for circuits up to 600 V AC, so it can be used on any copper conductor within that voltage limit.

What stud size and tongue width does this lug need to mount?

It requires a 1/4 in stud and has a tongue width of 0.52 in for a single-hole connection.

How is the 4 AWG copper wire crimped, and what step is often missed?

Strip the conductor, insert fully into the seamless barrel, then compress with a die code 29 tool; the step often missed is verifying full insertion before crimping.
