Thomas & Betts B14 Non-Insulated Ring Terminal

The B14 non-insulated ring terminal is built for 18 to 14 AWG wire. Anything heavier than 14 AWG won't seat in the barrel, and below 18 AWG you won't get a reliable crimp. The barrel is serrated to bite into the conductor and hold it.

Two stud sizes: B14-6 for a #6 stud and B14-8 for a #8 stud. The part number suffix is the stud size, so order by the screw or stud diameter on your terminal block or ground point.

Thomas & Betts lists WT110M, WT111M, WT112M, WT2000 and ERG4002 as application tools, with ERG4002 and ERG4005 called out as recommended. Single-indentor tools work; a double-indentor crimp is recommended when you're terminating solid wire.

No. The B14 non-insulated ring terminal is built for 18-14 AWG wire, so a 6 AWG conductor will not enter the barrel. For 6 AWG, step up to a heavy-wall compression lug such as the Burndy YAV6CL1BOX Hylug, a one-hole 6 AWG ring terminal sized for a #8-10 stud. Keep the B14 for the small control and signal conductors it is rated for.

They sit at opposite ends of the conductor range. The B14 is a light-gauge, non-insulated electro tin-plated copper ring terminal for 18-14 AWG wire, 0.03 inch stock thickness, rated 600V and 150 degrees C, crimped with a hand tool such as the ERG4002 or ERG4005. The Burndy YAV6CL1BOX belongs to the Hylug series and is a one-hole 6 AWG ring terminal for a #8-10 stud, a compression lug for feeder-size cable. Pick by the wire you are terminating.

Yes. The B14 is rated to 150 degrees C and 600V, which is well above what insulated nylon or vinyl barrel terminals handle. Because there's no insulation on the barrel, you supply the covering yourself with heat shrink or sleeving if the installation needs strain relief or a touch barrier.

It carries both UL and CSA, is RoHS compliant, and the flammability rating is UL 94 V-0. That covers most institutional and government spec language for a copper ring tongue terminal.

Electrolytic copper body with an electro tin-plated finish, metallic in appearance. Copper-to-copper means no dissimilar-metal concern on copper lugs, pads or bus, and the tin plate slows oxidation on the contact face. Stock thickness is 0.03 inch.

Non-insulated, like the B14, is the choice when you need the 150 degree C rating, when you're heat-shrinking over the joint anyway, or when a spec calls for a bare copper tongue you can inspect. An insulated barrel terminal is easier for fast work in a panel where you want built-in strain relief and color-coded wire sizing. The B14 gives up that convenience for temperature headroom and a serrated barrel that grips the conductor.

The B14 non-insulated ring terminal is offered in #6 and #8 stud sizes, so a #10 bolt will not pass through either tongue. For a #10 stud, the Burndy YAV6CL1BOX Hylug is a one-hole ring terminal sized for #8-10 studs, though its barrel takes 6 AWG rather than small-gauge wire. Match the stud and the conductor together before ordering.

They're sold each but ordered in multiples of 100. The inner pack is 100 pieces and the outer carton holds 500, so an MRO crib or service truck restock lands naturally on 100 or 500 counts.

Dimensionally the B14 runs 0.59 inch on the M dimension and 0.27 inch on the C dimension, with 0.03 inch stock. That's a compact tongue for an 18-14 AWG terminal, but on dense block spacing measure your centers against the 0.27 inch figure before committing to a quantity.
