Sta-Kon RD10731 – Frequently Asked Questions
1) What wire size and stud size does the Sta-Kon RD10731 ring terminal take?
The RD10731 is built for 8 AWG wire and a 3/8 inch stud. The red insulation is the color code Sta-Kon uses on this one, so if you are matching a bin of terminals by color on the truck, red here means the 8 AWG body, not the 22-18 AWG red you see on small-gauge barrels.
2) Can I use this nylon insulated ring terminal on a 600 volt panel circuit?
Yes. The RD10731 carries a 600 V rating and is UL recognized under file E9809, so it is suited to standard 600 V building and control panel wiring.
3) Is the Sta-Kon RD10731 terminal copper or aluminum, and can I land aluminum conductor in it?
The barrel is copper. That makes it a copper-only terminal, so use it on copper 8 AWG conductor. Aluminum conductor needs a terminal rated AL or AL/CU with the proper inhibitor, which this is not.
4) Do I need a special crimper for an 8 AWG Sta-Kon ring terminal?
Yes, plan on a heavy-duty crimper. At 8 AWG this is beyond the capacity of the small plier-style tools that handle 22-10 AWG insulated terminals; an 8 AWG copper barrel needs a large-frame ratcheting or hydraulic crimper with the matching die. Hand-squeezing it will leave a loose, high-resistance joint.
5) What is the difference between a nylon insulated ring terminal and a vinyl one?
Both insulate the barrel, but nylon takes higher heat and resists abrasion and cracking better than vinyl, which is why nylon versions like the RD10731 are the usual pick for motor connections, equipment enclosures and anywhere the lug may flex or get knocked. Vinyl is the lower-cost choice for light-duty, cooler indoor work.
6) Should I use a ring terminal or a fork terminal on an 8 AWG feeder connection?
Use the ring. A 3/8 inch ring like the RD10731 is a closed barrel that cannot slip off a stud if the nut backs off, which is why ring terminals are required on vibrating equipment and generally preferred on power connections. Spade and fork terminals exist so you can land a wire without fully removing the screw, a convenience that matters on control terminal strips, not on an 8 AWG power lead.
7) Where is the Sta-Kon RD10731 made?
Manufactured in Mexico. That is the stated country of origin if you need it for a submittal package or a procurement form requiring origin disclosure.
