Thomas & Betts 54142-TB – Frequently Asked Questions

1) What wire size does the Thomas & Betts 54142-TB copper lug take?
The 54142-TB is sized for a single #2 AWG copper conductor. It's a one-hole compression lug, so it terminates one #2 conductor per lug, not doubled conductors. If your feeder is a different gauge, you need the matching lug for that size, because the barrel is drawn for #2 and will not crimp reliably on anything larger or noticeably smaller.
2) What crimp die do I need for the T&B 54142-TB lug?
Die code 33, brown color code. Set your compression tool to the 33 die and match the brown index and the crimp will meet the lug's rating. Using an unmarked or mismatched die is the usual cause of a loose barrel on inspection.
3) Will this lug fit a flat bus bar or breaker pad without spacing problems?
It's a straight tongue with a standard tongue width and a round bolt hole, so the palm lands flat on a bus bar or breaker lug pad with no offset or twist. Published dimensions are B 0.88 in, E 0.41 in and F 0.375 in. If your pad has two bolt holes on centers, this is a one-hole lug and won't span them, you'd want a two-hole tongue instead.
4) How do I verify the conductor is fully seated in a compression lug?
This one has a peep hole in the barrel. You push the stripped #2 conductor in until copper strands show through the inspection hole, then crimp. That gives you and the inspector a visual check that the wire bottomed out before the die was closed, which a closed-barrel lug won't.
5) Is a tin-plated copper lug OK for a panel or motor control center in a damp or industrial space?
Yes. The lug body is copper for conductivity, with a tin plating over it that slows oxidation at the pad and inside the barrel. That's the standard choice for panelboard, MCC and distribution gear terminations where the connection may sit for years before anyone touches it again. It's also RoHS compliant if your facility or specifier requires that.
6) What is the difference between a standard barrel lug and a long barrel lug?
The 54142-TB uses a standard barrel and standard barrel shape, which means one crimp location and a shorter overall body. A long barrel version takes two crimps and is specified where a spec calls for higher pull-out strength or where the terminal sits under vibration. For ordinary panel, distribution and control terminations on #2 copper, the standard barrel is the normal call.
7) How is the 54142-TB copper lug packaged for a larger job?
Sold each, packed 25 to an inner carton and 250 to the outer. For crews terminating a run of #2 feeders that makes it easy to send a 25-count box out with each truck rather than counting singles. Weight works out to 3.38 lbs per 100 pieces.
