Sta-Kon RC250 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RC250 female disconnect crimp onto?
The RC250 is sized for 12-10 AWG stranded or solid copper wire, which is what the "12-10" in the description refers to. The yellow nylon insulation is the standard color code for that gauge range, so on a panel where you also have red (22-16) and blue (16-14) terminals, yellow is the one you reach for on 12 and 10 gauge conductors. Using it on a smaller conductor will not give you a reliable crimp.
2) Is the RC250 disconnect fully insulated, and what is the insulation made of?
The barrel and body are covered in a nylon/polyamide insulating sleeve, not vinyl. Nylon holds up better to crimping pressure and to heat and abrasion than vinyl, which is why it is the usual choice for motor leads and control panel work where the terminal may be pulled or flexed during service.
3) Is the Sta-Kon RC250 terminal UL recognized?
It carries UL file E66716. If you are terminating in a listed panel or on equipment that requires UL recognized components, that is the file number to reference on your submittal.
4) Do I need a specific crimper for these nylon insulated disconnects?
Yes, and it needs to be set for the gauge. The RC250 takes 12-10 AWG, so use the yellow-coded nest or die on an insulated-terminal crimper. Non-insulated dies will cut or split the nylon sleeve and leave the barrel under-compressed. The crimper is not included with the terminals.
5) What metal is the RC250 crimp barrel, and does that matter for the connection?
The terminal body is brass. Brass gives you good conductivity for a quick-connect joint, and because it is softer than steel it forms cleanly around a 12-10 AWG conductor when crimped with the matching die. Use a crimp tool rated for insulated nylon terminals in that gauge range, not a generic pliers-style tool.
6) Is the Sta-Kon RC250 made in the USA?
Country of origin is the United States. That matters on government, institutional, and some utility jobs where domestic-sourced components are a condition of the contract.
7) What part number do I order for a Sta-Kon 1/4 inch female disconnect in 12-10 AWG?
RC250 is the manufacturer part number, and it is a single configuration, so there is no finish, color, or gauge option to pick. One number covers it.
