Sta-Kon RC10-12 – Frequently Asked Questions
1) What wire size does the Sta-Kon RC10-12 ring terminal crimp onto?
The RC10-12 is sized for 12-10 AWG stranded copper conductor. Yellow insulation is the standard color code for that range, so if you are pulling 12 or 10 AWG into a lug or bolted stud, this is the right barrel. For 16-14 AWG you need a blue-coded terminal, and for 22-18 a red one.
2) Is this ring terminal rated for 600 volt circuits?
Yes. The nylon insulated Sta-Kon RC10-12 carries a 600 V rating, which covers it for standard commercial branch circuits, panel and control cabinet terminations, and motor connection boxes.
3) Is the Sta-Kon RC10-12 UL listed?
It is covered under UL file E9809. That is the reference an inspector or a spec reviewer will want when the terminal is going into a listed assembly or a panel build.
4) Should I use a ring terminal or a fork terminal on a bolted stud?
Use the ring. A ring terminal like the RC10-12 is a closed barrel design that cannot vibrate off the stud without the nut coming fully off, which is why it is the one specified for motor leads, grounding studs, and anything that sees vibration. A fork (spade) terminal is faster to service because it slides out from under a loosened screw, so it is the choice on terminal strips you expect to rework.
5) Is the barrel on the Sta-Kon RC10-12 copper or aluminum?
Copper. That means it terminates copper conductor directly with no dissimilar-metal concern. If you are landing aluminum conductor, you need a terminal rated AL-CU, not this one.
6) Does the nylon insulation hold up better than vinyl on this terminal?
The RC10-12 uses a nylon insulating sleeve rather than vinyl. Nylon is the tougher choice where the terminal gets pulled through a wire way or sits in a hot panel, and it resists abrasion and cut-through better during installation.
7) Is the Sta-Kon RC10-12 made in the USA?
Country of origin is the United States, which matters if you are filling a government or institutional order with domestic-content language in the spec.
8) What part number do I order for a 12-10 AWG ring terminal with a 1/2 inch ring?
Sta-Kon RC10-12. One model, no finish or size options to pick, so the part number is all you need for a reorder or a standardized panel build kit.
