Sta-Kon RA333 – Frequently Asked Questions
1) What wire sizes does the Sta-Kon RA333 ring terminal accept?
The RA333 is sized for 22 to 16 AWG stranded copper conductors. The red insulation is the standard color code for that range, so if you have a bin of mixed terminals the red barrel tells you it is the 22-16 AWG size at a glance. For 16-14 AWG you need the blue-coded size instead, and for 12-10 AWG the yellow.
2) Will the RA333 ring terminal fit a #6 screw or stud?
Yes, the ring tongue on the RA333 is drilled for a No. 6 bolt or screw. That makes it the right pick for small terminal blocks, control panel ground screws, and device terminals using #6 hardware. Larger studs need a bigger tongue size, since the ring is a closed barrel and will not slip over a #8 or #10 thread.
3) Is this ring terminal rated for 600 volt control and branch circuit wiring?
The Sta-Kon RA333 carries a 600 V rating, which covers typical commercial control panel, motor control, and 120/208/277/480 V branch circuit terminations. It is UL recognized under file E9809.
4) Should I use a ring terminal or a fork (spade) terminal on a panel screw?
A ring terminal like the RA333 is a closed tongue: the screw has to come all the way out to install or remove it, but once torqued down the connection cannot vibrate loose off the screw. A fork or spade tongue slides in under a loosened screw, which is faster for service work on crowded terminal strips. For equipment that vibrates, for grounding, or anywhere a loose wire is a safety issue, the closed ring is the one to specify.
5) What is the barrel made of, and does it matter for aluminum conductors?
The barrel is copper with nylon insulation over it. Copper barrels are intended for copper conductors only, so do not crimp this onto aluminum wire, use a connector marked AL or AL/CU for that. The nylon insulation holds up better to abrasion and crush than vinyl, which is why it is preferred in control cabinets where harnesses get pulled through.
6) Do I need a special crimp tool for the Sta-Kon RA333?
Insulated nylon ring terminals in the 22-16 AWG range crimp with an insulated-terminal crimper using the red nest, matched to the wire color code. A proper ratcheting insulated crimper is what gets a UL-compliant connection, general purpose pliers or an uninsulated-terminal die will crush the nylon and give you a joint that pulls out. The terminal itself ships ready to crimp, no separate insulating sleeve to add.
7) Where is the Sta-Kon RA333 made? We have domestic sourcing requirements.
Country of origin on the RA333 is the United States, which is what government, transit, and other Buy American influenced procurement will be looking for on the submittal.
8) What is the exact part number to order this red ring terminal under?
The manufacturer part number is RA333, branded Sta-Kon. Describing it out loud: insulated nylon ring terminal, 22-16 AWG, No. 6 bolt size, red.
