Burndy Long Barrel Telecom Copper Lug

This Burndy compression lug is a commercial-grade copper connector designed for terminating 4 AWG stranded copper wire. It suits installers and maintenance teams who need a reliable crimp termination in telecom or industrial power applications. The straight tongue and two-hole pattern simplify mounting on standard busbars or equipment pads.

4 AWG stranded copper wire only

The lug accepts a single conductor size: 4 AWG stranded copper, minimum and maximum. It is not suitable for any other gauge, for solid conductors, or for aluminium wire. Buyers who need to terminate larger or smaller cables, or who work with different conductor materials, must select a different lug.

Rated to 35 kV and 194 °F

The copper body is UL 486A-486B listed and CSA certified for continuous operation up to 35 kV and 194 degrees Fahrenheit. It handles typical telecom DC distribution and medium-voltage AC circuits within those limits. Installations exceeding either the voltage or temperature rating will require a differently rated connector.

Questions about this item

What does the 35 kV rating mean once the lug is crimped into a panel?

The lug is UL listed for continuous service up to 35 kV when correctly crimped on 4 AWG copper conductor.

Which standard governs the two-hole mounting pattern and what does it limit?

UL 486A-486B and CSA certification cover the 0.625 in hole spacing and the 35 kV voltage ceiling.

What clearance does the 2.600 in barrel length and 0.5 in tongue width require?

The straight tongue measures 0.5 in wide and the barrel extends 2.600 in, so allow at least that depth behind the mounting surface.
