Thomas & Betts B14-10 – Frequently Asked Questions

1) Will the Thomas & Betts B14-10 ring terminal fit a #10 screw or stud?
Yes. The B14-10 is built for a #10 stud size, so it drops onto #10 terminal screws on breakers, terminal blocks, switches, and equipment lugs. If your stud is larger, you need a different tongue size in the same T&B B series rather than forcing this one.
2) Is the B14-10 terminal insulated, and does that matter for a crowded panel?
It is non-insulated, bare electro tin-plated copper. In a tight panel or junction box that means the barrel and tongue are live metal, so you either shrink-sleeve the barrel or keep clearance from adjacent conductors and the enclosure. If you want factory insulation on the barrel, choose an insulated ring terminal instead of this one.
3) What crimper do I need for Thomas & Betts B series bare ring terminals?
T&B lists the WT110M, WT111M, WT112M, WT2000 and ERG4002 as application tools, with the ERG4002 and ERG4005 called out as recommended. Any of those will set the serrated barrel properly. Pliers or a generic insulated-terminal crimper will not give a controlled crimp on a bare barrel.
4) I need a ring terminal for 6 AWG on a #10 stud, not small control wire. What should I use?
The T&B B14-10 is a small-gauge terminal and will not take 6 AWG. For heavy conductor on the same hardware, the Burndy YAV6CL1BOX Hylug is a 6 AWG one-hole ring terminal sized for #8-10 studs, which covers that stud range with a much larger barrel.
5) What ring terminal should I use if the conductor is 6 AWG instead of 16-14 AWG?
The Thomas & Betts B14-10 ring terminal is built for 18-14 AWG wire on a #10 stud, so a 6 AWG conductor will not seat in its barrel. For that size, the Burndy YAV6CL1BOX Hylug is a 6 AWG one-hole ring terminal with a #8-10 stud hole, so it accepts the larger conductor while still landing on the same #10 stud.
6) Is the Burndy YAV6CL1BOX a direct substitute for a T&B B14-10?
No. Both are ring terminals that fit a #10 stud, but they cover different conductor ranges: the Thomas & Betts B14-10 crimps 18-14 AWG, while the Burndy YAV6CL1BOX Hylug is sized for 6 AWG. They are not interchangeable on the same wire, and the YAV6CL1BOX also calls for heavy-conductor crimping rather than the WT110M, WT111M, WT112M, WT2000 or ERG4002 tools listed for the B14-10.
7) Can I use the B14-10 ring terminal on a 600V motor control circuit running hot?
It is rated 600V and 150 degrees C, which covers motor control centers, panel feeders, control wiring and HVAC equipment connections where conductor insulation is typically rated 90 C or lower. The terminal is also UL 94 V-0 for flammability.
8) How are these bare ring terminals packaged, and is there a minimum order quantity?
They are sold each, but in multiples of 100. The inner pack is 100 pieces and the outer carton holds 500, so a typical MRO buy lands on even hundreds. For reference, the terminals run about 2.5 lbs per 1000 pieces.
9) My stud is #8, not #10 - does that change which ring terminal I order?
Yes. The Thomas & Betts B14-10 is dedicated to a #10 stud size, so on a #8 stud the tongue hole is oversized. The Burndy YAV6CL1BOX Hylug is specified for a #8-10 stud, covering both diameters, but it is a 6 AWG terminal - so it only solves the stud question if your conductor is that heavy. For 18-14 AWG wire on a #8 stud, stay within the T&B B series and step to the matching #8 stud tongue.
10) Do I need an insulated ring terminal instead of the B14-10?
The Thomas & Betts B14-10 is a non-insulated copper terminal with an electro tin-plated finish, rated 600V and 150 degrees C, which suits panel and motor-control landings where the terminal is covered by the enclosure or heat-shrink is applied separately. The Burndy YAV6CL1BOX Hylug is likewise a bare lug rather than a pre-insulated barrel, so if your spec calls for factory insulation on the crimp, neither of these is the part - choose an insulated-series terminal in the matching wire range.
11) What are the physical dimensions of the B14-10 ring terminal tongue?
T&B publishes four dimensions for this terminal: A 0.75, B 0.31, C 0.27 and M 0.59 inches, with a stock thickness of 0.030 inch. Use those against your stud spacing and washer face before committing, since the 0.030 inch stock sets how much the tongue adds under the nut.
12) Is the Thomas & Betts B14-10 RoHS compliant for a spec job?
Yes, the B14-10 bare ring terminal is RoHS compliant, which is what most institutional and government submittals ask for on electrical components.
13) Will a bare copper ring terminal hold up in a damp or corrosive environment?
The copper barrel is electro tin-plated, which is the standard plating for corrosion resistance on bare terminals and keeps the crimp interface from oxidizing. In genuinely wet or outdoor locations, seal the connection with adhesive-lined heat shrink since the terminal itself carries no insulation.
