Thomas & Betts LL414 – Frequently Asked Questions

1) What wire sizes does the Thomas & Betts LL414 lay-in grounding lug accept?
The LL414 lay-in lug takes conductors from #14 AWG up to #4 AWG, so one part covers everything from small equipment bonding jumpers to a #4 grounding electrode conductor. If your conductor is larger than #4, this is the wrong lug and you need a bigger body.
2) Can I use an aluminum grounding lug on copper ground wire?
The LL414 body is aluminum with a tin plated finish. Tin plating over aluminum is what makes a connector suitable for use with either copper or aluminum conductors, since the plating keeps dissimilar metals from contacting directly. Check the conductor marking stamped on the lug or its packaging against the conductor you are landing before you torque it.
3) What is the advantage of a lay-in lug over a standard bolt-on grounding lug?
With a lay-in design you drop the conductor into an open slot and tighten the setscrew, instead of threading the wire through a closed barrel. That matters when the ground wire is already run and terminated at the other end, or when you are landing a continuous bonding conductor that you do not want to cut. A closed-barrel mechanical lug is the better choice when you want the conductor fully captured on all sides.
4) Do I need a crimping tool or die set to install the LL414 grounding lug?
No. This is a mechanical setscrew connector, not a compression lug, so it installs with a hand tool and no crimper or die set. That makes it practical for field work in a panel, at a service entrance, or on equipment where you cannot get a crimp tool in.
5) What is the correct Thomas & Betts part number for a #14 to #4 AWG lay-in lug?
LL414 is the Thomas & Betts catalog number for the tin plated aluminum lay-in lug covering #14 through #4 AWG. Use that number when ordering or matching what is already installed on a job.
6) Is the Thomas & Betts LL414 lug sold individually or in a bag?
The LL414 is sold each, so you order the exact count you need for a panel board, switchgear enclosure, or a run of equipment grounds rather than buying a fixed carton.
7) Does the LL414 grounding lug come insulated?
No insulation on this one. It is a bare tin plated aluminum body, which is normal for grounding and bonding terminations. If your application calls for an insulated termination, this is not the part.
