Sta-Kon RC250M – Frequently Asked Questions
1) What wire size does the Sta-Kon RC250M female disconnect take?
The RC250M is sized for 12-10 AWG wire, which is the yellow color code on insulated terminals. If you're crimping 16-14 AWG, you need a blue-coded terminal instead, and 22-18 AWG takes red. Crimping a smaller conductor into the yellow barrel gives you a loose joint that will heat up.
2) What is the insulation on this Sta-Kon disconnect made of, and does it hold up in a hot panel?
The sleeve is nylon (polyamide), not vinyl. Nylon runs at a higher temperature rating than PVC and resists cracking and abrasion better, which is why it's the usual choice for control panels, motor connections and anywhere the terminal gets flexed or pulled during service.
3) What does the "Mylar" in the RC250M description mean?
The RC250M includes a Mylar sleeve over the disconnect body, an added insulating barrier on the receptacle so the connection stays covered after it's pushed onto the tab. Useful where terminals sit close together on a crowded starter or terminal block and you want to limit the chance of an accidental short.
4) What exact part number do I order for this Sta-Kon yellow 12-10 female disconnect?
Order Sta-Kon RC250M. That single part number covers the nylon insulated female .250 disconnect with the Mylar sleeve for 12-10 AWG wire; there are no size or finish choices to specify.
5) Is the terminal barrel brass or steel?
Brass. The conducting barrel and receptacle on the RC250M are brass, so you get a solid-conducting, corrosion-resistant joint rather than a plated-steel one. Crimp it with a tool matched to insulated terminals in the 12-10 AWG range.
6) Is the Sta-Kon RC250M made in the USA?
Country of origin is the United States. That matters on government, institutional and utility work where domestic-sourcing language shows up in the purchase order.
