Sta-Kon RA833 – Frequently Asked Questions
1) What wire sizes does the Sta-Kon RA833 ring terminal accept?
The RA833 is sized for 22 to 16 AWG stranded copper wire, which is the red color code band on insulated terminals. If you're terminating 14 or 12 AWG, you need the blue (16-14) or yellow (12-10) range instead, not this one.
2) What stud or screw size does the RA833 ring terminal fit?
The ring is drilled for a No. 8 stud or screw. It will slip over a #8 machine screw or terminal block stud; a #10 or 1/4-20 stud won't pass through, so step up to a larger ring for those.
3) Is the RA833 ring terminal UL listed for panel and institutional work?
It is covered under UL file E9809, which is what an inspector or a spec writer on an institutional job will be looking for on an insulated terminal. The 600 V rating is part of that same listing.
4) Why choose a ring terminal like the RA833 over a spade or fork terminal?
A ring terminal is captive: the stud passes all the way through, so the conductor cannot vibrate off a partially loosened screw. That's why rings are specified on motors, transformers, grounding points and anything that sees vibration. A fork or spade terminal slides off sideways and is only worth using where you need to pull a wire off a crowded terminal block quickly. The RA833 is the #8 stud, 22-16 AWG version.
5) Is the RA833 barrel copper or aluminum, and can I use it on aluminum conductors?
The barrel is copper, so it is for copper conductors only. Terminating aluminum wire with a copper-only connector risks galvanic corrosion at the joint; aluminum needs an AL/CU rated connector with the proper inhibitor compound.
6) I'm standardizing terminal stock across a facility. What does the RA833 cover and what else will I need?
The RA833 covers one combination: 22-16 AWG copper conductor on a No. 8 stud. For a full MRO drawer you'll also want the same red 22-16 range in #6 and #10 ring sizes, plus blue (16-14) and yellow (12-10) rings in the stud sizes your equipment uses. Keeping all of them nylon insulated means one crimp tool and one color system across the shop.
7) What kind of insulation is on the RA833, and does it hold up in hot equipment enclosures?
The insulation is nylon rather than vinyl. Nylon sleeves resist abrasion and cracking better than vinyl and tolerate higher temperatures, which is why they are the usual pick inside motor terminal boxes, rooftop HVAC units and switchgear. The nylon also supports the wire as it leaves the barrel, cutting down on strand breakage from flexing.
8) Do I need a special crimper for Sta-Kon RA833 terminals?
Insulated nylon ring terminals in the 22-16 AWG range crimp with a standard insulated-terminal tool using the red nest or die. An uninsulated-terminal crimper will cut the nylon sleeve instead of compressing it, and pliers will not give you a repeatable pull-out strength, so use the color-matched insulated die.
9) Are Sta-Kon RA833 terminals made in the USA for Buy American jobs?
Country of origin on the RA833 is the United States, which matters on federal, military and some state and transit contracts with domestic sourcing language. Pair that with the UL E9809 file reference and most submittal packages are satisfied.
