Sta-Kon RC777 – Frequently Asked Questions
1) What wire size does the Sta-Kon RC777 ring terminal take?
The RC777 is built for 12-10 AWG conductor. The yellow vinyl insulation is the standard color code for that range, so on a panel where blue is 16-14 and red is 22-16, yellow tells the next electrician it's a 12-10 crimp without pulling the wire. Undersized wire in this barrel will not hold a proper crimp, so step down to the correct color for smaller conductors.
2) Is the Sta-Kon RC777 rated for 600 volt circuits?
Yes, the insulation carries a 600 V rating, which covers standard commercial branch circuits, control panels, and motor leads up to 600 V. It is UL recognized under file E9809.
3) Is the RC777 terminal copper or aluminum, and can I use it on aluminum wire?
The barrel is copper, so it is a copper-to-copper connection. Use it on copper conductors only. Aluminum branch wiring needs a terminal specifically listed AL/CU, and this one is not that part.
4) Why use a ring terminal instead of a spade or fork terminal on a panel?
A ring tongue is closed, so it cannot slip off the stud if the nut backs off under vibration. That is why ring terminals are the choice for grounding screws, motor leads, and anything on a machine that moves. A fork or spade terminal is faster to service because you only have to loosen the screw, not remove it, which is why they still show up on control terminal strips. The RC777 covers the ring side of that choice for 12-10 AWG on a No. 8 stud.
5) Do I need a special crimper for the Sta-Kon RC777?
Insulated terminals like this one crimp over the vinyl sleeve, so you want a crimper with the color-coded insulated-terminal nest, yellow station for 12-10 AWG. A bare-terminal indent crimper will cut the insulation instead of forming it. No tool is supplied with the terminal itself.
6) Is the Sta-Kon RC777 made in the USA?
Country of origin is the United States. For agencies, school districts, and federal MRO buyers working to domestic sourcing requirements, that is the relevant data point on this terminal.
7) What is the exact part number for the yellow 12-10 AWG No. 8 Sta-Kon ring terminal?
Order it as Sta-Kon RC777. That single MPN covers the yellow vinyl insulated ring terminal, 12-10 AWG, No. 8 stud, rated 600 V.
