Sta-Kon RC10-516X – Frequently Asked Questions

1) Will a Sta-Kon RC10-516X ring terminal work on 12 AWG and 10 AWG wire?
Yes. The RC10-516X is sized for 12-10 AWG conductors, so either gauge crimps correctly in the same barrel. Yellow nylon insulation is the standard color code for that 12-10 range, which makes it easy to confirm the right terminal on a panel build without re-reading the stamp.
2) Is the Sta-Kon RC10-516X UL listed for commercial and institutional work?
It carries UL file E9809, which is the listing inspectors and spec writers look for on an insulated terminal in commercial panel and equipment wiring. It is also made in the United States, which matters on jobs with domestic sourcing requirements.
3) Should I use a ring terminal or a fork terminal on a 5/16 stud?
Use the ring. A ring terminal is a closed barrel, so the nut has to come all the way off before the conductor can leave the stud, which is why rings are specified for grounding connections and anything subject to vibration. A fork or spade slides out under a loosened nut, so it is only worth using where you need to pull wires out of a crowded terminal block quickly. This Sta-Kon is the closed ring version in the 12-10 AWG, 5/16 stud size.
4) Can I use this terminal for an equipment grounding conductor?
Yes. Equipment grounding is one of the applications it is intended for, and the copper barrel with a 5/16 ring suits a ground bus or bonding stud of that size. On a 12 or 10 AWG ground conductor it is a direct fit.
5) Is the barrel copper or aluminum, and can I put it on aluminum wire?
The terminal body is copper, so it is for copper conductors only. Aluminum branch or feeder wire needs a terminal marked AL or AL9CU with the appropriate compound; crimping aluminum into a copper barrel sets up a dissimilar-metal joint that will loosen and heat up.
6) What is the exact part number to order this Sta-Kon ring terminal?
Order Sta-Kon RC10-516X. The RC prefix is the nylon insulated ring, the 10 covers the 12-10 AWG range, and 516 is the 5/16 stud. If you need a different stud on the same wire range, the stud number in the part code is what changes.
