Thomas & Betts 54143-TB – Frequently Asked Questions

1) Will the Thomas & Betts 54143-TB lug take #2 AWG copper wire only, or can I use it on a smaller conductor?
The 54143-TB is built for #2 AWG copper. It's a compression lug, so the barrel is sized to one conductor and crimped with the matching die; putting a smaller conductor in it won't give you a proper compression. For a smaller wire, order the lug made for that AWG size.
2) What die do I need to crimp the T&B 54143-TB compression lug?
Set your compression tool to die code 33, which T&B color-codes brown. Use that die index and you'll get the correct crimp on the standard barrel; a mismatched die is the usual cause of a loose or over-compressed termination.
3) How can I tell the conductor is fully seated before I crimp this lug?
There's a peep hole in the barrel. Push the stripped conductor in until you can see copper through the hole, then crimp. That visual check is why inspectors like these on service and switchgear work.
4) Is a tin-plated copper lug okay for outdoor or damp electrical enclosures?
The tin plating over copper is there for corrosion resistance and to keep the contact surface clean over time, which is what you want in damp or dusty environments and at aluminum bus interfaces. The base metal is copper, so use it on copper conductors.
5) How are these #2 AWG T&B lugs packaged if I'm buying for a full job?
Sold each, with 25 to an inner pack and 250 in the outer carton. Shipping weight runs 3.13 lbs per 100 pieces, useful if you're quoting freight on a full 250-count box.
6) Is this T&B compression lug RoHS compliant for a government or institutional spec?
Yes, the 54143-TB is RoHS compliant, and the barrel carries standard T&B marking for wire size and die code so an inspector can verify the crimp after the fact.
