Thomas & Betts 14RB-14 – Frequently Asked Questions

1) Will the insulation sleeve on this blue T&B ring terminal slide over THHN with thick jacket?
The PVC sleeve accepts conductor insulation up to 0.17 inches in outside diameter. Standard building wire in this gauge range falls under that, but heavily jacketed or double-insulated appliance wire can exceed it. Measure the insulation OD before crimping, because forcing an oversize jacket into the sleeve splits it and you lose the strain relief the extended barrel is there to provide.
2) What crimper do I need for a Thomas & Betts RB series insulated ring terminal?
ERG4001 is the recommended tool. T&B also qualifies the WT145C, WT2000, WT112M and ERG4003 for this terminal. Using an unrated crimper on an insulated barrel is the usual cause of low pull-out values, since the die has to compress the brazed serrated barrel without crushing the vinyl sleeve.
3) Is this ring terminal rated for 600V control panel wiring?
Yes, the RB series insulated ring terminal carries a 600V rating with a 105 C temperature rating, which covers typical industrial control panel, motor control center and distribution equipment wiring. The sleeve is UL 94 V-0 for flammability, and the part is RoHS compliant.
4) How many ring terminals come in a pack, and do I have to buy in multiples?
They ship 100 to an inner pack, and 100 is the order multiple, so quantities go up in hundreds. The outer carton holds 500. Weight runs 0.37 lbs per 100 pieces, which is worth knowing if you are staging kits on a service van.
5) What is the exact part number to reorder this Thomas & Betts ring terminal?
Order by manufacturer part number 14RB-14, from the Thomas & Betts RB insulated ring terminal series. An alternate package designation, RB717, is also published for the same terminal in a different pack configuration.
6) Will these terminals corrode in a damp mechanical room or outdoor enclosure?
The barrel and tongue are copper with an electro tin-plated finish, which is the standard plating for resisting surface corrosion and keeping contact resistance low on a screw stud. Tin plating also avoids the galvanic issue you get putting bare copper against an aluminum bus. Stock thickness on the tongue is 0.03 inches.
7) What does the blue sleeve on this T&B terminal mean on a job site?
Blue is the standard color code electricians use to identify a mid-range insulated terminal at a glance, so a panel builder can sort terminals by gauge band without reading the stamp. On the 14RB-14 the color is blue and the sleeve is vinyl, extended past the barrel to relieve bending stress where the wire exits.
