Sta-Kon RC734 – Frequently Asked Questions
1) What wire size does the Sta-Kon RC734 ring terminal take?
The RC734 is sized for 12-10 AWG conductor. Yellow is the standard color code for that range, and the barrel is copper, so it belongs on copper wire, not aluminum. For 16-14 AWG or 22-18 AWG runs you need a different terminal in the series.
2) What stud or screw size does the Sta-Kon RC734 ring fit?
The ring tongue is a 3/8 inch size, so it drops over a 3/8 inch stud, bolt or terminal screw on a lug, breaker or ground bar. If your stud is 1/4 or 5/16, this ring will sit loose on it and you want the smaller tongue version.
3) Is this ring terminal rated for 600 volt control and panel wiring?
Yes. The RC734 carries a 600 V rating and is UL recognized under file E9809, which covers typical 480Y/277 and 208Y/120 panel, motor control and equipment wiring. The nylon insulation sleeve is what provides the insulated rating at the crimp.
4) Why pick a nylon insulated ring terminal over a vinyl one or a bare lug?
Nylon takes more abuse than vinyl: it resists abrasion and cracking when the terminal is pulled through a wire way or flexed in a panel door, and it holds up better at elevated temperature. Against a bare lug, the insulated sleeve means no separate boot or tape at the crimp. The RC734 is the nylon insulated type in copper, 600 V rated.
5) Can I use the Sta-Kon RC734 on aluminum conductors?
No. The RC734 barrel is copper and should be crimped on copper conductor only. Terminating aluminum needs a terminal listed AL9CU or AL7CU with the appropriate oxide inhibitor, which this one is not.
6) Do I need a special crimp tool for the RC734 terminal?
Use a crimper matched to insulated terminals in the 12-10 AWG range, which is the yellow die position on most color coded ratcheting tools. Pliers or a generic cutter crimper will not form the barrel correctly and the UL E9809 recognition assumes a proper crimp. The tool is a separate purchase.
7) Is the Sta-Kon RC734 made in the USA?
Country of origin on the RC734 is the United States, which matters on federal, state and institutional jobs carrying domestic sourcing requirements.
8) What is the exact part number to order for a yellow 3/8 inch ring terminal in 12-10 AWG?
Order Sta-Kon RC734. That is the manufacturer part number for the nylon insulated copper ring terminal, 12-10 AWG, 3/8 inch stud, 600 V.
