Sta-Kon RC2217-250M – Frequently Asked Questions
1) What wire size does the Sta-Kon RC2217-250M locking fork terminal accept?
It's sized for 12-10 AWG conductors. The yellow vinyl insulation is the standard color code for that range, so on a panel you can spot the 12-10 crimps at a glance without pulling the wire. For 16-14 AWG you need a blue-coded terminal instead, and 22-16 AWG takes red.
2) Is the barrel on this Sta-Kon fork terminal copper or aluminum?
Copper. That means it is intended for copper conductors, not aluminum wire, where you'd need a terminal rated AL/CU with the appropriate inhibitor compound. Pairing a copper-only barrel with aluminum conductor is the usual cause of a hot, high-resistance joint.
3) What is the difference between a locking fork terminal and a plain spade terminal?
A locking fork has turned-up tangs at the ends of the fork tines, so once the screw is tightened the terminal cannot slide back off the stud the way an open spade can. You still get the spade advantage of sliding under a loosened screw instead of removing it, which is why they get used on terminal blocks and motor control panels where screws are hard to reach. The RC2217-250M is that locking style in 12-10 AWG.
4) Is the Sta-Kon RC2217-250M UL listed?
Yes, it carries UL file E9809. That's the listing an inspector or spec writer will want referenced for a UL-recognized crimp termination on a 12-10 AWG conductor.
5) Do I need a special crimp tool for Sta-Kon RC2217-250M terminals?
These are crimp terminals, not screw or solder lugs, so they need a ratcheting or plier-type crimper with a die matched to the 12-10 AWG yellow insulated range. Using the wrong die nest (a 16-14 blue nest, for instance) either crushes the insulation or leaves the barrel under-compressed, and the UL E9809 listing only applies to a properly made crimp.
6) What part number and brand should I order for a yellow 12-10 AWG insulated locking fork terminal?
Sta-Kon RC2217-250M. That's the manufacturer part number to quote, and it is made in the United States, which matters if you're buying against a domestic-preference or Buy American line item.
7) Will vinyl insulated terminals hold up in a hot enclosure or outdoors?
The insulation here is vinyl, which is a general-purpose indoor and panel material. For high-heat work near motors, ballasts, or engine compartments, buyers normally step up to a nylon-insulated or heat-shrink barrel terminal instead of vinyl. If the location also sees moisture, an adhesive-lined heat-shrink terminal is the one to specify.
