Thomas & Betts RB14-14 – Frequently Asked Questions

1) What wire gauge does the Thomas & Betts RB14-14 blue ring terminal take?
The RB14-14 is sized for 18 to 14 AWG conductors, which is why the insulation sleeve is blue. Blue is the standard color code for that gauge band across insulated terminals, so if your panel wiring is #16 or #14 control wire, this is the right size. Anything heavier than 14 AWG needs a yellow-band terminal instead, and 22-16 AWG wire belongs in a red one.
2) Will the nylon sleeve on this blue ring terminal fit over the insulation on my wire?
The barrel accepts conductor insulation up to 0.162 inch in outside diameter. Standard THHN and machine tool wire in the 18 to 14 AWG range sits under that, but heavy-wall or double-insulated leads can exceed it, so measure the jacket OD before you order a full box. The sleeve is nylon with an inner bronze grip sleeve that clamps the insulation, which is what stops the conductor from creeping back out under vibration.
3) What crimp tool do I need for Thomas & Betts RB Series nylon ring terminals?
Thomas & Betts lists the ERG4001 as the recommended tool for the RB terminals. The full approved list is WT2000, WT112M, WT145C, ERG4001, ERG4003 and WT145A. Nylon-insulated terminals need a nest matched to the insulation grip, so a bare-terminal or generic auto-parts crimper will crush the sleeve and give you a connection that will not hold under pull test.
4) Can these ring terminals be used in a 480V motor control center or control panel?
The RB Series insulated ring terminal is rated 600V, so it covers 480V control and power circuits as well as standard 120/277V work. Temperature rating is 105 degrees C, which suits enclosed panels and MCC cubicles that run warm. The sleeve carries a UL 94 V-2 flammability rating.
5) Is a ring terminal or a spade terminal the better choice for panel terminations?
Use a ring where the connection is on a stud or a screw you can fully remove, and where vibration or a code-required ground bond means the lug must not be able to slip off. The closed ring on the RB14-14 has to be threaded over the stud, so the screw comes all the way out during install. A fork or spade slides in under a loosened screw and is faster for dense terminal strips you service often, but it can work loose. Ground connections and motor lead studs are ring territory.
6) How many ring terminals come in a pack and can I order less than 100?
They ship 100 to a bag, and 100 is the order multiple, so quantities go up in hundreds rather than singles. A full case is 500. Figure roughly 0.37 lbs per 100 pieces if you are estimating a van stock or a shipment weight.
7) Are these terminals copper, and will they hold up in a damp or corrosive environment?
Copper barrel with an electro tin-plated finish. The tin plating is what keeps the crimp surface from oxidizing over time and losing conductivity, and it also makes the terminal safe to land on aluminum or tin-plated bus without the galvanic problem bare copper creates. Stock thickness is 0.030 inch. The part is RoHS compliant.
8) What is the exact part number for the Thomas & Betts blue 18-14 AWG ring terminal?
Order it as Thomas & Betts RB14-14, in the RB terminal series. The same terminal is cataloged under RB713 as an alternate package quantity, so if a spec sheet or an old PO shows RB713 you are looking at the same terminal in different packaging.
