Copper Mechanical Connector for 250–350 kcmil Wire

This Burndy terminal accepts stranded copper conductors from 250 kcmil up to 350 kcmil. It mounts on a 5/8 in stud and carries a 600 V rating. The single-hole hex head simplifies installation with standard tools.

Sustained Load Performance

The copper body operates continuously at temperatures up to 194 degrees F without degradation. The .31 in tongue thickness and 1.5 in width maintain firm contact area under thermal cycling. The .69 in hole diameter matches the stud for secure mechanical retention.

Upgrade From Smaller Lugs

Installers moving from lugs rated below 250 kcmil gain capacity for larger feeders in the same footprint. The jump is worthwhile when conductor size increases or when a single-hole hex mounting pattern is required. It does not suit applications needing multi-hole NEMA spacing or aluminium conductor compatibility.
