Burndy 4 AWG One-Hole Lug

The Burndy YAD4CM6E14 is a single-hole compression lug built for 4 AWG copper conductors. It suits panel-builders and electricians who need a reliable crimp termination on a 1/4-inch stud. The long barrel provides extra contact area for secure connections in industrial and automotive electrical work.

600 V Rating and 302 °F Limit

Rated for 600 volts and a maximum operating temperature of 302 degrees F, the lug handles typical low-voltage power distribution and control circuits. The tin-plated copper barrel resists corrosion while maintaining conductivity. It is not suited for voltages above 600 V or environments exceeding the stated temperature ceiling.

Brazed Barrel and UL 467 Listing

The brazed barrel construction prevents the seam from opening under mechanical stress or vibration. A tongue width of 0.47 inches fits standard 1/4-inch studs cleanly. UL 467 listing confirms compliance for grounding and bonding applications, removing the need for separate qualification in inspected installations.

Questions about this item

Will the 0.47 in tongue width fit the same 1/4 in stud I use with my existing 4 AWG cables?

Yes, the lug is built for a 1/4 in stud and the 0.47 in tongue matches that bolt size, so it will sit on the same stud as your current 4 AWG ring terminals.

How can I confirm the crimp is solid once I press the lug onto 4 AWG wire?

After crimping, the barrel should show a uniform indent with no loose strands visible; the brazed barrel and tin-plated copper contact give a consistent 0.43 in barrel length that resists pull-out when correctly compressed.

Does the package include heat-shrink or any insulation, or do I need to buy that separately?

The lug ships bare with no insulation material and no heat-shrink tubing, so you will need to supply your own insulating cover if the installation requires it.
