Sta-Kon RA257M – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RA257M female disconnect accept?
The RA257M is sized for 22-18 AWG stranded or solid copper wire, which is what the red insulation color indicates on insulated terminals. If your conductor is 16-14 AWG you need the blue-barrel size instead, and 12-10 AWG takes yellow.
2) Will this Sta-Kon disconnect fit a 1/4 inch male tab?
Yes. The RA257M is a 250 series female disconnect, meaning it mates with a .250 inch (1/4 inch) wide male tab or quick-connect blade, the common size on contactors, relays, fan motors and appliance terminals. It will not seat properly on .187 or .110 tabs.
3) Do I need a special crimp tool for the Sta-Kon RA257M?
It is an insulated crimp terminal, so use a crimper with the color-coded insulated-terminal nest, red die for the 22-18 AWG range. A bare-terminal or uninsulated die will crush the vinyl sleeve and give you an unreliable connection. No solder needed.
4) Is the RA257M a female or male quick disconnect?
Female. The RA257M is the receptacle half, so it slides onto a male tab. If you need the mating blade end on the other conductor, order a 250 series male disconnect in the matching 22-18 AWG red size.
5) What are the barrel and insulation made of on this red female disconnect?
Copper barrel with a vinyl insulating sleeve. Copper gives the conductivity and crimp ductility you want on control wiring; the vinyl sleeve is the common choice for general indoor and panel work rather than nylon, which holds up better to flexing and higher heat.
6) Are Sta-Kon disconnects made in the USA for government or institutional orders?
Country of origin on the RA257M is the United States, which is what procurement officers on federal, education and healthcare jobs usually need confirmed for domestic-preference requirements.
