Thomas & Betts 54906BE – Frequently Asked Questions

1) What cable size and stud size does the Thomas & Betts 54906BE lug take?
The 54906BE Color Keyed copper lug terminates 4 AWG conductor and bolts to a 1/4 inch stud. One hole, one barrel, sold each, so order one per conductor you are landing.
2) Can I use this lug on medium voltage cable in switchgear?
Yes. The 54906BE carries a 35 kV voltage rating, which covers medium voltage terminations in switchgear, metal-clad gear and power distribution equipment. It is a bare copper lug with no insulation, so the cable termination needs its own stress relief or boot per the application.
3) Is this a compression lug or a mechanical set-screw lug?
It is a compression (crimp) lug. The long barrel is crimped onto the conductor with a hydraulic or battery crimper and the correct die for the color code, which is gray on this one. If you want a lug you can land with a hex key and no tooling, you need a mechanical set-screw lug instead.
4) Can I crimp a copper lug onto aluminum conductor?
No. The 54906BE barrel is copper and is for copper conductor only. Landing aluminum in a copper-only barrel is a mismatch, so for aluminum feeders use an aluminum or dual-rated AL9CU compression lug in the matching size.
5) Will a 1/4 inch stud lug bolt to my 3/8 inch busbar stud?
No. The pad on the 54906BE is drilled for a 1/4 inch stud, so it will not pass a 3/8 or 1/2 inch bolt, and drilling the pad out is not acceptable practice. Match the lug's hole to the stud on the breaker, bus or ground bar. For a 1/2 inch stud on large copper feeders, the Burndy YA31L is a 1/2 inch stud lug.
6) What is the closest equivalent to the Thomas & Betts 54906BE long barrel copper lug from another manufacturer?
The nearest peer is the Burndy HYLUG long barrel tin-plated copper terminal lug. Both are long barrel compression lugs on copper, so both are crimped onto the conductor rather than set with a bolt. The difference to confirm before you order is plating and sizing: the 54906BE is copper in the Color Keyed line with gray color coding, sized for 4 AWG cable with a 1/4 inch stud, while the Burndy peer is tin-plated copper. Match the conductor size and stud diameter in your gear before substituting either way.
7) I need a copper compression lug for a 350 kcmil feeder landing on a 1/2 inch stud - will the Thomas & Betts 54906BE work?
No. The 54906BE is built for 4 AWG cable on a 1/4 inch stud, so the barrel will not accept a 350 kcmil conductor and the tongue hole is too small for a 1/2 inch bolt. For that opening use the Burndy YA31L Hylug, a 350 kcmil copper one-hole compression lug with a 1/2 inch stud. Both are crimp lugs, so your die set changes with the barrel size.
8) What does the gray color on the barrel mean?
Gray is the Color Keyed index for this lug, part of the Thomas & Betts color coding system. It tells the installer which crimp die and die index to use so the connector, conductor size and tool all match up, and it gives a visual check after the crimp that the right connector went on the right wire.
9) Why pick a long barrel lug instead of a standard barrel?
The longer barrel takes two crimps instead of one, which gives more contact area and more pull-out strength on the conductor. That is why it is the usual choice on vibration-prone gear, motor control centers and medium voltage terminations. On a short, low-stress tap in a panel a standard barrel lug does the same electrical job in less space.
10) Is the Thomas & Betts 54906BE lug UL listed?
Yes, it is listed under UL file E9809. That is the third-party listing inspectors look for on compression connectors used in commercial and industrial installations.
11) What other long barrel copper compression lugs are there if 4 AWG with a 1/4 inch stud is the wrong size?
For larger feeders, the Burndy YA31L Hylug is a 350 kcmil copper one-hole compression lug with a 1/2 inch stud hole. Burndy's HYLUG long barrel tin-plated copper terminal lug is the tin-plated alternative in the same family of long barrel crimp lugs. For Square D Masterclad switchgear specifically, the Masterclad Burndy crimp lug connector accessory is the gear-matched part.
12) Does it matter whether I use a tin-plated copper lug or a bare copper lug like the 54906BE?
It is the main material difference between the 54906BE and the Burndy HYLUG long barrel lug, which is tin-plated copper. The 54906BE is copper in the Color Keyed line, with gray color coding that identifies the die and conductor size at a glance during inspection. Tin plating is typically specified where the termination will see a more corrosive or dissimilar-metal environment. Both are long barrel designs for crimped terminations, so decide based on what your spec or inspector calls for at the landing.
13) Does the 54906BE lug come with the mounting bolt or hardware?
No hardware is included. The lug is sold as a single piece, each, so the stud nut, washers and any Belleville hardware come from the gear or are bought separately. Crimp dies are also separate and need to match the gray color code.
