Sta-Kon RZ22-4 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RZ22-4 ring terminal accept?
The RZ22-4 is sized for 26 to 22 AWG stranded wire, which is the smallest of the common insulated terminal ranges. If you're terminating 20 or 18 AWG, this barrel is too small to crimp reliably and you want the next range up. The yellow nylon insulation is the color code Sta-Kon uses on this 26-22 size, so don't assume yellow means 12-10 AWG the way it does on some other brands' vinyl terminals.
2) What stud or screw size does the RZ22-4 ring fit?
The ring is a No. 4 stud size, so it drops over a #4 screw or terminal stud. On a control panel or a low voltage device with #6 or #8 terminal screws, the ring won't pass over the stud and you need the matching larger ring in the same 26-22 AWG range.
3) Can I use these ring terminals on 480V equipment?
No. The RZ22-4 carries a 600 V rating, which covers standard 120/208/240/277/480 V building and control circuits up to that limit. Anything above 600 V needs a terminal rated for that class.
4) Ring terminal or fork terminal for a control panel terminal block?
Use the ring where the connection must not back out. A ring like the RZ22-4 is a closed barrel that captures the #4 screw completely, so vibration or a loose screw won't let the wire slip free, which is why it's the choice for motor controls, terminal studs, and anything subject to movement. A fork or spade slides out from under a loosened screw, and its only real advantage is that you can land or remove it without fully backing the screw out.
5) Is the barrel on the Sta-Kon RZ22-4 copper or aluminum?
Copper, with nylon insulation over it. That makes it a copper-only terminal: land copper conductors in it, not aluminum, since a dissimilar-metal joint in a copper barrel isn't a listed combination. Nylon rather than vinyl insulation also means better abrasion and crush resistance when you're pulling a harness into a wireway.
6) What is the exact part number to order for a yellow 26-22 AWG No. 4 ring terminal from Sta-Kon?
Order Sta-Kon RZ22-4. That single part number covers the yellow nylon insulated ring terminal for 26 to 22 AWG wire with a No. 4 stud ring, rated 600 V.
7) Do I need a special crimper for Sta-Kon nylon insulated terminals?
Use an insulated-terminal crimp tool matched to the 26-22 AWG range. Nylon insulated barrels are crimped through the insulation with a color-coded or AWG-marked insulated die, not with the open-barrel nest used for non-insulated terminals. A die sized for a larger gauge will under-crimp a 26-22 barrel and the wire will pull out.
