Thomas & Betts 54111 – Frequently Asked Questions

1) What wire sizes does the Thomas & Betts Color Keyed standard barrel copper lug come in?
Two conductor sizes are offered: 4 AWG (part 54106) and 3/0 AWG (part 54111). The barrel is sized to the conductor, so order by the cable you are actually terminating rather than trying to make one size cover both. They sell individually, one lug each.
2) Can I use this lug on medium voltage cable terminations?
The lug carries a 35 kV voltage rating, so it is suitable for medium voltage terminations up to that class as well as ordinary low voltage panel and switchgear work. It is a bare, uninsulated barrel with no insulation material, so the termination itself has to be insulated or sealed by the kit or tape build-up you are using.
3) Do I need a special crimp tool and die for these Color Keyed lugs?
Yes. This is a compression lug in the Thomas & Betts Color Keyed line, which is a die-indexed system: the barrel is color coded to the conductor size and you match that color index on the die in your hydraulic or battery crimper. The 4 AWG barrel is gray. A mechanical set screw lug is the alternative if you do not own a compression tool.
4) Is this lug copper or aluminum, and can I land it on an aluminum bus?
It is copper bodied and intended for copper conductors. Copper to aluminum contact at a bus or pad is a dissimilar metal joint, so if your bus is aluminum you want a dual rated AL9CU connector or an approved bimetallic transition instead of a straight copper lug.
5) Is this a UL listed lug for an inspected commercial installation?
It is listed under UL file E9809, which is what an inspector on a commercial or industrial job will look for on a termination. That listing applies to the lug installed as intended, meaning correct conductor size and the matching compression die.
6) What is the difference between a standard barrel lug and a long barrel lug?
A standard barrel takes a single crimp and is the usual choice for panel, switchgear, and motor control terminations. A long barrel gives you room for two crimps, which is what specs call for on high vibration or high pull-out applications. These Thomas & Betts Color Keyed lugs are the standard barrel type, so if your drawing calls out a two-crimp long barrel termination, this is not the part.
7) How many lugs do I get when I order one?
One lug per order, not a bag or box. Count your terminations, including neutrals and grounds, and order accordingly, plus spares for a miscrimp since a compression lug cannot be reused once it is crimped.
