  • Product typeElectrical Connectors
  • Accepts copper or aluminium conductors up to 600 kcmil
  • Dual-conductor design terminates two cables in one lug
  • Single 1/2 in mounting hole simplifies panel installation
  • Hex socket head allows fast, secure tightening with standard tools
  • Aluminium body rated for 194 °F and 1 000 V operation

What this lug does

This BLACKBURN mechanical lug connects two conductors up to 600 kcmil each to a single 1/2 in stud. The aluminium body accepts stranded copper or aluminium wire from 2 AWG to 600 kcmil and is rated for 1,000 V at up to 194 Degrees F. A hex-socket head provides the clamping force for both terminations.

Who should use it and who should not

Installers needing a dual-conductor lug with a single mounting hole will find the 1.22 in hole spacing and 2.41 in tongue width fit standard patterns. Projects that require more than two conductors, a different stud size, or a higher temperature rating should look at other connector styles.

Behaviour under sustained load

The aluminium body and hex-socket hardware maintain clamping pressure during continuous operation at the rated 194 Degrees F and 1,000 V. The 0.44 in tongue thickness and 1.81 in tongue length provide stable contact area for both conductors under steady thermal cycling.

Questions about this item

What conductor sizes and materials does the ADR60-21 lug accept?

The lug is rated for stranded copper from 2 AWG up to 600 kcmil and also accepts aluminium conductors.

Can I use this two-conductor lug with a single 1/2 in stud on existing busbars?

Yes, it has one 0.5 in hole on 1.22 in spacing, a 1.81 in tongue length and 2.41 in width, so it fits standard 1/2 in stud patterns.

How do I verify the connection is correct after torquing the hex-socket screws?

Confirm each conductor is fully seated, the hex-socket screws are tight, and the lug body does not exceed 194 °F under load.
