SKU CH-DPQJ-TVGE7

A pack of ten pink copper compression lugs with seamless barrels and chamfered ends for easy 1/0 AWG conductor insertion

  • Seamless one-piece construction ensures reliable conductivity
  • Electro-tin plating resists electrolytic corrosion effectively
  • Chamfered barrel ends simplify conductor insertion
  • Installed with standard industry tooling easily
  • Pack of ten connectors for multiple jobs

3M 1/0 One-Hole Lug Compression Connector

These copper compression lugs are designed for terminating 1/0 AWG conductors in electrical installations. Each connector features one-piece seamless construction with electro-tin plating to resist electrolytic corrosion. Chamfered ends simplify conductor insertion during installation. The product is supplied in a pack of 10 units.

Check conductor size and tooling before ordering

Verify that your conductor is 1/0 AWG to match the lug specification. Ensure you have standard industry compression tooling suitable for copper lugs. Confirm the single-hole mounting configuration matches your busbar or terminal block layout. The pink copper colour coding identifies the correct conductor size range.

Suits installers terminating 1/0 AWG copper wire

Ideal for electricians and panel builders making permanent compression connections on 1/0 AWG conductors. Not suited for applications requiring two-hole mounting patterns or different conductor gauges. Buyers needing aluminium lugs or mechanical screw terminals should look at alternative connector types. The 30031 model addresses a specific copper compression requirement.

Questions about this item

Does the pack of 10 lugs include any crimping tools or heat-shrink tubing?

The pack contains only the 10 compression lugs. Crimping tools and insulation must be purchased separately.

Why is this lug coloured pink and marked for 1/0 AWG?

Pink is the industry colour code for 1/0 AWG copper conductors, so you can match the lug to the wire size at a glance.

What does the seamless one-piece barrel mean when I crimp it onto a cable?

The seamless barrel distributes crimp force evenly around the conductor, giving a low-resistance joint that resists pull-out and corrosion.
