One-Hole Compression Lug for 4 AWG Copper

This one-hole compression lug is built for terminating 4 AWG stranded copper conductors with a 1/4 inch stud. It suits electrical and industrial wiring tasks where a compact, short-barrel connector is required. The gray colour code and die code 29 identify the correct crimping tool. Installers working with copper wire in panels or equipment will find it matches the specified conductor range.

Crimp Termination Limits at 600 V AC

The lug is rated for a maximum of 600 V AC and an operating temperature up to 300 degrees F. Its seamless barrel and single inspection hole support reliable crimp connections within these electrical and thermal boundaries. The straight tongue and 0.55 inch width fix the physical clearance for the stud. Applications exceeding the voltage or temperature ratings need a different connector.

Short Barrel Length Decides Fit

The short barrel length is the critical dimension that determines whether this lug fits the available space in a terminal block or bus bar. A longer barrel would not seat correctly in tight enclosures, while this design keeps the overall profile minimal. Buyers who need a longer barrel for additional crimp area or a different stud size must select another part.

Questions about this item

Should I pick the short-barrel lug or look for a longer barrel for my 4 AWG copper wire?

The short barrel is built for 4 AWG copper only; choose it when panel space is tight and a standard crimp tool with die code 29 is available.

What does the 600 V AC rating mean when the lug is crimped onto a 4 AWG conductor in a panel?

It certifies the copper lug for continuous service up to 600 volts AC once properly crimped with a die code 29 tool and inspected through the hole.

How does the 1/4 in stud hole and seamless copper barrel limit the lug in a 300 °F environment?

The 1/4 in stud fixes the bolt size, while the seamless copper barrel and CSA/UL listing keep the connection reliable at the 300 °F maximum operating temperature.
