Sta-Kon RB257-200 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB257-200 female disconnect crimp onto?
The RB257-200 is sized for 16-14 AWG stranded or solid copper wire. The blue vinyl insulation is the standard color code for that gauge range, so if you are working a panel with mixed terminals, blue tells you at a glance it is the 16-14 barrel rather than a red 22-18 or yellow 12-10.
2) Will the RB257-200 fit a .250 inch male quick-disconnect tab?
Yes. It is a 250-series female disconnect, meaning it slides onto a standard 1/4 inch (.250) wide male blade tab, the tab size used on most appliance switches, relays, blower motors and thermostats. It will not fit a .187 (3/16) or .110 tab.
3) Is this Sta-Kon disconnect UL recognized?
The RB257-200 carries UL file E66716. For MRO and institutional work where terminations in a control panel have to be listed components, that file number is what an inspector or spec writer will want referenced.
4) Is the terminal body brass or steel, and does that matter for a copper wire run?
The barrel and receptacle are brass, which is what you want against copper conductors, no dissimilar-metal concern the way a plated steel terminal can present. The insulation sleeve over it is vinyl.
5) Should I use a female disconnect like the RB257-200 or a ring terminal?
Use the female disconnect where the connection has to come apart, a motor, a limit switch, a relay or a control board that gets swapped. It pushes onto a .250 male tab and pulls off without tools. A ring or fork terminal is the right choice when the wire lands under a screw on a terminal block or ground lug, where nothing needs to be disconnected in service.
6) Do I need a special crimper for the Sta-Kon RB257-200?
It is an insulated barrel terminal, so it wants an insulated-terminal crimp die, the color coded blue nest on a standard insulated crimp tool for 16-14 AWG. A bare-terminal or non-insulated die will cut the vinyl sleeve. No heat is involved, the vinyl is crimp-only, not heat shrink.
7) Is the Sta-Kon RB257-200 made in the USA?
Country of origin on the RB257-200 is the United States, which is the detail that usually decides it for government and institutional buyers working under domestic sourcing requirements.
8) What part number do I order for the blue 16-14 AWG 250 series female disconnect?
Order Sta-Kon RB257-200. That one manufacturer part number covers it, there is no separate finish or pack-size code to pick on this terminal.
