Thomas & Betts 2B-14 – Frequently Asked Questions

1) What wire gauges does the Thomas & Betts 2B-14 splice connector accept?
The 2B-14 butt splice takes 16 to 14 AWG conductors, one in each end. It's a B series non-insulated barrel, so both wires entering it have to fall inside that range. For anything heavier or lighter you need a different barrel size in the series, not this one.
2) What crimp tool do I need for the 2B-14 non-insulated butt splice?
Thomas & Betts lists the ERG4002 and ERG4005 as the recommended tools, with WT110M, WT111M, WT112M, WT2000 and ERG4002 also called out as application tools for this splice. A non-insulated barrel needs a proper crimper with the right nest; pliers will not give you a reliable crimp.
3) Does a non-insulated splice like the 2B-14 need separate insulation after crimping?
Yes. The 2B-14 is a bare electro tin-plated copper barrel with no insulating sleeve, so the splice has to be covered after crimping, normally with heat shrink or tape, unless it sits inside an enclosure where bare metal is acceptable. The upside is a smaller finished profile and direct metal-to-metal contact, which is why these get used in tight panel work.
4) Can the 3M SC0001 stem connector be used in place of a 2B-14 copper splice connector?
No. The 3M SC0001 is a stem connector rated up to 35 kV for 2 and 1 AWG conductors, which is medium-voltage, large-gauge cable work. The Thomas & Betts 2B-14 is a 600V non-insulated copper splice for 16-14 AWG wire. The two cover opposite ends of the wire range and completely different voltage classes, so they are not interchangeable in either direction. For 16-14 AWG control and branch circuit splicing, use the 2B-14.
5) I need to splice large feeder cable, not 16-14 AWG control wire. What should I look at instead of the 2B-14?
The Thomas & Betts 2B-14 only accepts 16-14 AWG copper, so it will not take feeder cable. For heavy conductors in the 2 and 1 AWG range, the 3M SC0001 stem connector covers that size and is rated up to 35 kV. Match the connector to the actual conductor size and the system voltage class on your drawing.
6) Can I use the 2B-14 splice in a 600V control panel running hot?
It's rated 600V with a 150 degree C temperature rating, which covers standard commercial and industrial control wiring and motor-adjacent runs where ambient and conductor temperatures climb. The barrel also carries a UL 94 V-0 flammability rating.
7) What's the difference between a non-insulated butt splice and a twist-on style connector like the Leviton ML2?
Two different jobs. The 2B-14 is a crimped copper barrel that joins two conductors end to end in line, 16-14 AWG, and needs a crimp tool plus separate insulation. The Leviton ML2-C midget connector, also sold in 100 packs, is a screw-on style wire connector that twists on by hand. Use the crimp splice where you want a permanent inline joint with minimal bulk; use the twist-on where you're pigtailing conductors in a box and want it serviceable without a tool.
8) Can I use these splices on 2 AWG feeder conductors?
No. The 2B-14 tops out at 14 AWG. For heavy conductors in that range you want a large-gauge connector such as the 3M SC0001 stem connector, which covers 2 and 1 AWG and is rated to 35 kV. Don't try to force oversized conductors into a 16-14 barrel; the crimp won't hold.
9) Is the Leviton ML2-C midget connector an alternative to the Thomas & Betts 2B-14 splice connector?
They are different kinds of connection. The Thomas & Betts 2B-14 is a non-insulated electro tin-plated copper splice connector for 16-14 AWG wire, rated 600V and 150 C, and it is crimped onto the conductors with a tool such as the ERG4002 or ERG4005. The Leviton ML2-C is a midget connector for electrical wiring supplied in packs of 100. If the job calls for a crimped butt splice on 16-14 AWG copper, the 2B-14 is the part; the ML2-C is a different connector style, so confirm the connection method the drawing or the equipment requires before swapping.
10) If I want an insulated connector instead of a bare crimp splice, what are my options?
The Thomas & Betts 2B-14 is a non-insulated splice, so the splice has to be insulated separately with tape or heat shrink after crimping, which is why it suits tight panel work where a bulkier insulated body will not fit. If you would rather not insulate in the field, the Leviton ML2-C midget connector is an alternative connector style sold in packs of 100. Choose based on whether your inspection requires a factory-insulated body or the compact bare crimp.
11) How are these splices packaged and is there a minimum order quantity?
They come 100 to the inner pack and order in multiples of 100, with 500 to the outer carton. Thomas & Betts sells the item as each, but you buy it in the 100 count increment, which suits MRO stockrooms keeping a bin of 16-14 AWG splices on the shelf.
12) Will tin-plated copper splices hold up in a damp or corrosive environment?
The barrel is copper with an electro tin-plated finish, which is there for conductivity plus corrosion resistance on the exposed metal. Because it's non-insulated, the crimp still needs covering in wet or washdown areas. The part is also RoHS compliant, which matters if you're specifying for an OEM build or a green building spec.
