Sta-Kon RC10-516 – Frequently Asked Questions
1) What wire size does the Sta-Kon RC10-516 ring terminal crimp onto?
The RC10-516 is sized for 12 to 10 AWG stranded copper conductor. The yellow nylon insulation is the color code for that 12-10 range, so if you are terminating 16-14 AWG you need a blue-coded terminal instead, and 22-16 AWG takes red.
2) What is the voltage rating on the Sta-Kon RC10-516 nylon insulated ring terminal?
Rated 600 V, which covers standard building branch circuits, control panels, and motor connections. It also carries UL file E9809.
3) Is the RC10-516 terminal barrel copper or aluminum?
The barrel is copper. That makes it a copper-only connector, suitable for copper conductor terminations, not for aluminum wire.
4) Should I use a ring terminal or a fork terminal on a panel stud?
Use the ring style, like the Sta-Kon RC10-516, anywhere the connection is on a stud that stays captive and vibrates, since the closed 5/16 inch tongue cannot back off the screw if the nut loosens. A fork or spade terminal only makes sense where you need to slide the lead off without fully removing the hardware, which is typical of service-access terminal strips. For vehicle, motor, and generator work, inspectors and most specs expect the ring.
5) Does the nylon insulation on this ring terminal need separate heat shrink?
No. The RC10-516 comes with the nylon insulating sleeve already on the barrel, rated to 600 V, so the crimp is covered as installed. Nylon takes a crimp better than vinyl without splitting and resists abrasion in conduit bodies and panel wireways.
6) Is the Sta-Kon RC10-516 made in the USA for a Buy American job?
Country of origin is the United States, which matters on federal, state, and institutional work carrying domestic sourcing requirements.
