Thomas & Betts RB250 – Frequently Asked Questions

1) What wire size does the Thomas & Betts RB250 female disconnect take?
The RB250 is sized for 16-14 AWG stranded or solid copper wire, which is why the insulation is blue. Blue is the standard color code for the 16-14 AWG range, so if you are crimping 22-18 AWG you want a red-barrel terminal instead, and 12-10 AWG takes a yellow one.
2) What size male tab does this Thomas & Betts disconnect slide onto?
It is a .250 series female disconnect (the "FEM-250" in the RB250 description), so it mates with a 1/4 inch wide quarter-inch push-on tab, the most common tab size on contactors, relays, switches and motor terminals. It will not fit .187 or .110 tabs.
3) Is this terminal UL listed for panel and control wiring?
Yes. The RB250 carries UL file E66716, which is the listing a lot of inspectors and spec writers look for on control circuit and panel terminations. That covers electrical panel connections, control circuits, and equipment disconnect points.
4) Will a tin plated brass disconnect hold up in a damp mechanical room?
The barrel is brass with a tin plated finish, which is the standard pairing for corrosion resistance on copper wire terminations and keeps the contact from oxidizing at the crimp. The body is insulated in nylon/polyamide rather than vinyl, so it is tougher mechanically and stands up better to abrasion and heat than a PVC-sleeved terminal.
5) Do I need a special crimper for a nylon insulated disconnect?
Use an insulated-terminal crimper matched to the blue 16-14 AWG die. Nylon barrels are stiffer than vinyl, so a plain uninsulated or non-ratcheting tool tends to crack the sleeve or under-crimp the barrel. The RB250 is a crimp-on terminal, nothing else ships with it.
6) Is this the female or the male half of a quarter-inch quick disconnect?
Female. The RB250 is the receptacle half that slides onto a male .250 tab, either a spade tab built into the device or a male disconnect crimped onto the mating wire. If you are terminating both ends of a wire-to-wire splice, you need one of each.
7) Is the RB250 sold in bags of 100 or individually?
The selling unit is each, so quantity ordered is the number of terminals. If you are stocking a truck or a maintenance crib, order the count you need rather than assuming a bagged 100-pack.
