Thomas & Betts 54165-TB – Frequently Asked Questions

1) What wire size does the Thomas & Betts 54165-TB compression lug take, and can I use it on aluminum conductor?
The 54165-TB is sized for 3/0 AWG conductor only, and the barrel is copper with a tin-plated finish. It's a copper lug, so use it on copper conductor. For aluminum you need a lug rated AL/CU or an aluminum-bodied terminal instead.
2) Which crimp die do I set my compression tool to for the T&B 54165-TB lug?
Die code 50, orange. That color code is stamped on the lug so you can match it to the die set in the field, and the barrel is a standard barrel and standard length, so standard compression tooling applies rather than a long-barrel die sequence.
3) What is the closest alternative to the Thomas & Betts 54165-TB for a larger conductor on the same 1/2 inch stud?
The Thomas & Betts 54165-TB is a 3/0 AWG copper compression lug with a single round 1/2 inch bolt hole. If the conductor is larger than 3/0, the Burndy YA31L Hylug is a 350 kcmil copper 1-hole compression lug that also lands on a 1/2 inch stud, so the bolt pattern at the bus stays the same while the barrel accepts the bigger cable. Wire size, not stud size, is what decides between them.
4) How much room do I need in the panel gutter for a 3/0 T&B compression lug?
The 54165-TB measures 2.35, 1.25, 0.92, 0.63, 0.5 and 0.13 inches across its published A through F dimensions. Overall length is 2.35 inches, so allow at least that much straight run past the landing pad plus bending radius for 3/0 copper.
5) Are these T&B lugs sold individually or only by the box?
The 54165-TB is sold each. Packaging runs 10 to an inner pack and 100 to the outer carton, so a full carton of 100 weighs 8.88 lbs.
6) Standard barrel versus long barrel compression lug, which do I need?
The T&B 54165-TB is a standard barrel, meaning a single crimp location and standard die sequence. Long barrel versions, like the Burndy HYLUG tin-plated copper terminal lugs, take multiple crimps over a longer barrel and are specified where higher pull-out strength or utility practice calls for it. If your spec just says compression lug, standard barrel is the normal choice.
7) Can I use this lug inside metal-clad switchgear?
It is a general-purpose one-hole compression lug for panels, switchgear and motor control terminations. If your gear manufacturer requires a listed accessory lug for the compartment, use theirs instead, for example the Square D Masterclad crimp lug connector accessory for Masterclad switchgear.
8) Should I use a long barrel lug instead of the Thomas & Betts 54165-TB?
The 54165-TB uses a standard barrel with a standard barrel shape, crimped with an orange die, code 50. A long barrel lug such as the Burndy HYLUG long barrel tin-plated copper terminal lug gives a longer crimp area, which some specifications call for on high-current or vibration-prone terminations. Both are tin-plated copper; the choice comes down to whether the drawing or the equipment terminal calls out a long barrel and whether you have the die set for it.
9) Which lug lets me verify the conductor is fully inserted before crimping?
The Thomas & Betts 54165-TB has a peep hole in the barrel, so you can sight the conductor end before compressing with the orange die. Among the copper compression alternatives, the Burndy YA31L Hylug 350 kcmil 1-hole lug and the Burndy HYLUG long barrel terminal lug are identified by series and conductor rather than by an inspection hole, so if visual insertion check is part of your QC sign-off, the 54165-TB is the one that documents it.
10) What is the peep hole on a compression lug for?
It lets you see that the conductor is fully seated in the barrel before you crimp. The 54165-TB has one, which matters on an inspected job where you need to prove insertion depth rather than guess at it.
11) Is the Thomas & Betts 54165-TB lug RoHS compliant for a spec job?
Yes, it is RoHS compliant, with a tin-plated copper body. The tin plating is also what you want where the termination sees humidity or corrosive atmosphere rather than bare copper.
