Sta-Kon RL9731 – Frequently Asked Questions
1) What wire size does the Sta-Kon RL9731 ring terminal take?
The RL9731 is sized for 3/0 AN wire, which is what the "3/0AN" in the part description refers to. Crimp it only on conductor of that size. Undersized wire in a 3/0 barrel will not hold mechanically and oversized wire will not seat, so match the gauge before you crimp.
2) What voltage is the Sta-Kon RL9731 nylon insulated ring terminal rated for?
600 V. The nylon insulation on this ring terminal carries a 600 volt rating, which covers typical branch circuit, panel, and control wiring work. It is also UL recognized under file E9809.
3) Is the RL9731 terminal barrel copper, and can I use it on aluminum conductor?
The barrel is copper, so it is intended for copper conductor. Copper terminals on aluminum wire create a dissimilar metal joint that corrodes and loosens, so for aluminum feeders use a terminal rated AL9CU or aluminum specific instead of this one.
4) Do I need a special crimp tool for a 3/0 ring terminal like this one?
Yes. A 3/0 barrel is a heavy lug size, well beyond what a hand crimper for insulated 22-10 AWG terminals will close. You need a hydraulic or heavy mechanical crimper with a die matched to the 3/0 copper barrel. Budget for that tool and die when you order, because the terminal does not include one.
5) Should I use a ring terminal or a spade terminal for a 3/0 connection?
Use the ring. A ring terminal like the RL9731 captures the 3/0 conductor fully around the 3/8 stud, so it cannot back off the stud if the nut loosens. A spade or fork terminal pulls off sideways and is only appropriate for small control conductors where fast service access matters more than retention. On a 3/0 power connection, ring is the right call.
6) Why is the Sta-Kon ring terminal red, and does the color mean anything on the job?
Red is the insulation color on the RL9731. On nylon insulated terminals the color is the manufacturer's wire range code, so crews use it as a quick visual check that the right size terminal went on the right conductor during inspection or troubleshooting. It has no electrical meaning on its own.
7) Where is the Sta-Kon RL9731 made? I have country of origin requirements on a government job.
The RL9731 ring terminal is manufactured in Mexico. If your contract carries Buy American or TAA country restrictions, check that Mexico qualifies under the specific clause you are bound by before you submit it.
