  • Seamless one-piece copper construction ensures reliable conductivity
  • Electro-tin plating resists electrolytic corrosion for lasting performance
  • Chamfered barrel ends simplify conductor insertion during installation
  • Compatible with standard industry crimping tools for easy use
  • Pack of 10 connectors rated for 250 kcmil conductors

Compression Connector for 250 kcmil Conductors

This copper compression lug is built for terminating large-gauge conductors in electrical installations. The one-piece seamless barrel provides a reliable mechanical and electrical joint. It suits electricians and maintenance crews working on power distribution circuits. The pack contains ten connectors for multiple terminations.

Installed with Standard Industry Tooling

The lug accepts conventional compression tools already found in most electrical workshops. No proprietary crimp dies or specialised equipment are required for a proper connection. Chamfered barrel ends guide the conductor into place, reducing insertion effort and the risk of strand damage. Electro-tin plating protects the joint from electrolytic corrosion over time.

Pack Quantity of Ten Connectors

Each package supplies exactly ten lugs, matching the 31049 ordering code. Buyers needing a different count or a two-hole mounting pattern will need a separate part number. The yellow colour code identifies the 250 kcmil size at a glance during installation.

Questions about this item

Should I pick the PK10 pack or buy singles?

The item is supplied as a PK10 pack containing ten identical 250 kcmil lugs.

What does the 250 kcmil rating mean when I crimp it onto a cable?

It matches a 250 kcmil conductor so the barrel fills correctly and the crimp meets the intended cross-section.

How does the one-hole mounting limit the way I can bolt this lug down?

The single bolt hole provides one fixed attachment point; the lug cannot be double-bolted for extra mechanical security.
