Sta-Kon RC333 – Frequently Asked Questions
1) What wire size does the Sta-Kon RC333 ring terminal take?
The RC333 is sized for 12-10 AWG stranded copper conductors. The yellow nylon insulation is the color code for that range, so on a job where crews are mixing terminals, yellow is the 12-10 barrel. If you're terminating 16-14 AWG, this barrel is too large to crimp reliably and you want a blue-coded terminal instead.
2) Is the Sta-Kon RC333 UL listed, and what voltage is it rated for?
It carries UL file E9809 and is rated 600 V. That covers the usual control panel, motor lead, and branch circuit terminations where an inspector wants a listed termination on the conductor.
3) Should I use a ring terminal or a fork terminal for a motor terminal block?
Use the ring. A ring tongue like the RC333 is a closed barrel, so once the #6 screw is torqued the conductor can't back out even if the screw loosens; a fork (spade) slides out sideways. Forks are the choice only where you need to service the connection often without fully removing the screw. For vibration-prone equipment such as motors, compressors, and rooftop units, the closed ring is the safer termination.
4) Is the Sta-Kon RC333 made in the USA?
Country of origin on the RC333 is the United States, which matters if you're buying under a Buy American or domestic-preference clause on a government, transit, or federally funded project. The barrel is copper.
5) Do I need a special crimper for Sta-Kon nylon insulated terminals?
Use an insulated-terminal crimp tool matched to the 12-10 AWG (yellow) nest. A yellow-coded die on a controlled-cycle crimper compresses the copper barrel without splitting the nylon sleeve. Crimping a 12-10 barrel in a 16-14 nest will cut the insulation and under-form the barrel.
6) Will nylon insulation hold up better than vinyl on these ring terminals?
The RC333 uses a nylon insulating sleeve rather than vinyl. Nylon takes more abuse during pull-in and resists abrasion and cut-through better where a harness drags across a panel edge, and it handles higher temperatures than standard vinyl. That's why nylon-insulated terminals are what most spec writers call out for commercial control work.
7) What part number do I order to restock this yellow 12-10 ring terminal?
Order Sta-Kon RC333. That is the manufacturer part number, and it's a single configuration: yellow nylon insulated, 12-10 AWG, No. 6 stud ring.
