Sta-Kon RC10-38X – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RC10-38X ring terminal crimp onto?
The RC10-38X takes 12 to 10 AWG stranded copper wire. That is the yellow color code on Sta-Kon insulated terminals, so if you are pulling 14 or 16 AWG you need a blue-coded 16-14 barrel instead, not this one.
2) Can I use a nylon insulated ring terminal on a 480V motor circuit?
The RC10-38X carries a 600 V rating, so it covers 120, 208, 240, and 480 V power and control work. The nylon insulation sleeve is what gives it that rating, so do not strip the sleeve back or cut it down to make it fit a tight lug box.
3) Is the Sta-Kon RC10-38X UL listed for inspected work?
It is covered under UL file E9809. For a facility job or anything an AHJ will walk, that file number is what you put on the submittal alongside the 600 V and 12-10 AWG rating.
4) Why choose a ring terminal instead of a fork or spade terminal here?
A ring terminal is captive: the screw passes through a closed barrel, so the wire cannot pull off a loosened stud. That is why ring terminals are the choice for vibration-prone equipment, motor leads, grounding, and anything safety related. A fork or spade slides off sideways under a loosened screw, which is why people use it where terminals must be serviced quickly. The RC10-38X is the closed-ring version for a 3/8 inch stud.
5) Is the barrel on this ring terminal copper or aluminum?
Copper, with a nylon insulating sleeve over it. Use it on copper conductors. If your feeder is aluminum you need an AL9CU rated lug with the proper inhibitor, not a copper crimp barrel like this one.
6) Is the Sta-Kon RC10-38X made in the USA for Buy American jobs?
Country of origin is the United States, which is what government, military, and federally funded procurement usually needs documented. Pair that with UL file E9809 for the submittal package.
7) How do I identify the right Sta-Kon terminal by color on the truck?
Yellow is the 12-10 AWG band in the Sta-Kon insulated line, so the RC10-38X sleeve is yellow. Color gets you the wire range at a glance, but it says nothing about ring size, so check the stamped 3/8 inch ring before you crimp.
