Blackburn LL306 LAY IN LUG No6SOL - 3/0

The LL306 lay-in lug takes conductors from No. 6 solid through 3/0. That range covers most grounding electrode conductors and equipment grounding conductors on commercial service and panel work, so one lug part number can handle several conductor sizes across a job.

Yes. The LL306 carries UL file E9809 and is a mechanical grounding connector, which is what an inspector looks for when you are bonding a grounding electrode conductor or equipment ground to an enclosure, rack, or busbar.

The LL306 lug body itself is aluminum, which is the standard dual-rated construction for mechanical grounding connectors. Always land the conductor per the marking on the connector and use an approved joint compound where an aluminum conductor is being terminated.

A lay-in lug like the LL306 opens at the top so you can drop the conductor straight into the channel and tighten the setscrew, rather than pulling a cut end through a barrel or crimping with a die tool. That matters on a continuous grounding electrode conductor you do not want to cut, and on retrofit work where the wire is already run and terminated at the far end. A compression lug gives a permanent, tool-verified crimp; a lay-in is mechanical and serviceable.

No. The LL306 is a bare, uninsulated mechanical lug. If the application needs the termination covered, plan on separate insulating boot, tape, or heat shrink.

The LL306 is sold each, so you can order the exact count for the panel, rack, or ground bar you are wiring instead of buying a full carton.
