Thomas & Betts RB14-8F – Frequently Asked Questions
1) Will the Thomas & Betts RB14-8F fork terminal work on 16 AWG stranded control wire?
Yes. The RB14-8F covers an 18 to 14 AWG wire range, so 16 AWG sits in the middle of the barrel range. The blue nylon jacket is the standard color code for that range, which is why these are quick to sort on a panel job. Maximum insulation diameter the barrel will accept is 0.162 inches.
2) What stud or screw size does the RB14-8F fork terminal fit?
It is sized for a #8 stud. The fork tongue measures 0.31 and 0.25 inches across the published B and C dimensions, with overall A at 0.87 inches, so check the terminal block spacing if you are landing several side by side on tight centers.
3) What crimp tool do I need for the Thomas & Betts RB terminals?
Thomas & Betts lists the ERG4001 as the recommended tool for the RB14-8F. Also approved: WT145C, WT2000, WT112M, ERG4003, and WT145A. Use one of those rather than a generic plier crimper, since the insulation grip sleeve inside the barrel needs a proper die to form correctly.
4) Should I use a fork terminal or a ring terminal on a control panel terminal block?
A fork (spade) terminal like the RB14-8F slides in under a loosened #8 screw without removing it, which is why it is the common choice on terminal strips and control panels you expect to service. A ring terminal has to come off over the stud, but it cannot vibrate out. For motor connections and grounding points subject to vibration, go ring; for serviceable terminal blocks, the fork is faster.
5) How many RB14-8F terminals come in a pack and can I buy fewer than 100?
They ship 100 to the inner pack with an order multiple of 100, so 100 is the smallest quantity. The outer carton holds 500. Useful if you are stocking a truck or an MRO crib rather than buying for one job.
6) Are these terminals copper or aluminum, and will they hold up in a damp or corrosive location?
The barrel and tongue are copper with an electro tin-plated finish, which is the standard plating for corrosion resistance on copper conductors. Stock thickness is 0.030 inches. They are copper-only terminals, so do not use them to terminate aluminum conductors; that needs a dual-rated AL9CU connector.
7) Are the Thomas & Betts RB14-8F terminals RoHS compliant?
Yes, RoHS compliant. That matters if you are supplying into equipment builds or export panels where the bill of materials has to be documented.
