Thomas & Betts 14RB-6F – Frequently Asked Questions

1) What crimp tool works with Thomas & Betts RB fork terminals?
ERG4001 is the recommended tool. The terminal also crimps with the WT145C, WT2000, WT112M and ERG4003. Using a listed tool matters on the RB barrel because it is a brazed seam with internal serrations, and a generic pliers-style crimper will not develop the pull-out value the serrations are there to give you.
2) Will this fork terminal fit over the insulation on my 14 AWG THHN?
The insulation sleeve accepts wire insulation up to 0.17 inches in diameter. Standard 14 AWG THHN sits under that, so the extra-long PVC sleeve slides over the jacket and gives strain relief at the flex point. Heavy-jacketed or double-insulated cable above 0.17 inches will not enter the sleeve.
3) Is the 3M Highland BFV14 fork terminal a direct substitute for the Thomas & Betts 14RB vinyl fork terminal?
They are close but the wire ranges differ. The Thomas & Betts RB series insulated fork terminal is rated for 18-14 AWG copper wire with vinyl insulation, while the 3M Highland BFV14 series vinyl insulated fork terminal is specified for 16-14 AWG. If the panel or control wiring includes 18 AWG conductors, the RB terminal covers that end of the range; for 16 and 14 AWG runs both will land the wire. Match the stud size as well - the RB fork is offered as 14RB-6F, 14RB-8F and 14RB-10F for #6, #8 and #10 studs.
4) I am crimping 18 AWG instrument wire - which vinyl fork terminal should I order?
Use the Thomas & Betts RB series fork terminal, which covers 18-14 AWG and accepts insulation up to 0.17 in outside diameter. The 3M Highland BFV14 series vinyl insulated fork terminal starts at 16 AWG, so it is the wrong end of the range for an 18 AWG conductor. Crimp the RB with the recommended ERG4001 tool.
5) Should I use a fork terminal or a ring terminal on a stud?
A fork (spade) terminal like the RB Series slides under a loosened screw without removing it, which is why it is the usual choice on terminal blocks and control panels where you service wiring often. A ring terminal is captive and will not back out if the screw loosens, so it is the better call on vibrating equipment and on battery or motor studs. The RB fork comes in #6, #8 and #10 stud sizes for 18-14 AWG.
6) Is the RB Series fork terminal rated for 600V control panel wiring?
Yes, 600V with a 105 degree C temperature rating, which covers industrial control panels, motor control centers and commercial distribution gear. The vinyl insulation carries a UL 94 V-0 flammability rating, and the terminal is RoHS compliant.
7) What else could I use instead of the Thomas & Betts RB fork terminal?
A close alternative is the 3M Highland BFV14 Series vinyl insulated fork terminal, rated 16-14 AWG. Note the range is narrower than the RB Series at 18-14, so if you are terminating 18 gauge control wire the T&B is the one that covers it. 3M also offers a Highland vinyl-insulated block fork terminal if you want a block-style tongue rather than a standard fork.
8) What is the difference between a block fork terminal and the Thomas & Betts 14RB fork terminal?
The Thomas & Betts 14RB is a standard open fork (spade) tongue in electro tin-plated copper with vinyl insulation, sized 0.97 in overall with a 0.31 in tongue width. The 3M Highland vinyl-insulated block fork terminal uses a block-style fork tongue, a squared-off geometry intended to resist pulling off the stud under vibration. Both land under a screw or stud without removing the nut; choose the block fork where the terminal may be disturbed in service and the standard 14RB fork where you want the narrower tongue to fit tight terminal block spacing.
9) For a control panel that needs a 105 degree C and 600V rated terminal, does the Thomas & Betts 14RB meet it or should I look at the 3M Highland fork terminals?
The Thomas & Betts RB series insulated fork terminal carries a 600V rating, a 105 degree C temperature rating and a UL 94 V-0 flammability rating on the vinyl sleeve, and it is RoHS compliant - so it answers that panel spec directly. The 3M Highland BFV14 and Highland block fork terminals are vinyl insulated fork terminals in the same general class, differentiated mainly by wire range and tongue style rather than by those panel ratings.
10) How many fork terminals come in a pack and can I buy fewer?
They come 100 to a bag and order in multiples of 100. Plan quantities in hundreds rather than exact piece counts.
11) Is copper with tin plating better than bare for panel terminations?
The RB terminal is copper with an electro tin-plated finish, which is what you want for corrosion resistance and for landing on aluminum or plated hardware in an enclosure. Stock thickness on the tongue is 0.03 inches, so it seats flat under a washer without deforming.
