Copper Terminal for 500 kcmil Wire

This Burndy compression lug accepts a single 500 kcmil stranded copper conductor. It is built for commercial electrical installations that require a reliable crimp connection at up to 35 kV. The straight tongue and 1/2 in stud hole suit standard bus-bar or equipment mounting.

Capacity and Headroom

The barrel is sized for exactly 500 kcmil copper with no range above or below that gauge. It carries a 35 kV maximum voltage rating and a 194 °F temperature limit, so it handles heavy feeder circuits within those bounds. The brown colour code and die code 20 identify the correct crimp tool setting for this size.

Build Quality and Connectors

The copper body includes an inspection hole to verify full conductor insertion before energising. It meets UL 486A-486B, UL 467 and CSA certification for safety compliance. The 1.55 in tongue width and 3.400 in overall length fit standard 1/2 in hardware without adapters.

Questions about this item

Will the 1/2 in stud hole on this 500 kcmil copper lug match the bolt pattern on my existing bus bar?

The lug has a single 1/2 in stud hole and a straight tongue 1.55 in wide, so it will fit any bus bar drilled for a 1/2 in bolt on that centre-line.

How can I confirm the crimp is correct after installing the terminal?

The barrel carries an inspection hole; after crimping with a die marked 20 or 299 you should see the conductor through that hole, verifying full insertion.

Does the package include mounting hardware or heat-shrink tubing?

The box contains only the copper compression lug itself; bolts, washers and any insulating sleeving must be sourced separately.
