Sta-Kon C222M – Frequently Asked Questions
1) What wire gauge does the Sta-Kon C222M fork terminal take?
The C222M is sized for 12-10 AWG conductor. Anything smaller, like 16-14 or 22-18, will not hold in the barrel and the crimp won't pass a pull test, so match the terminal to the actual conductor you're landing, not to the screw size.
2) What size screw or stud does the C222M spade terminal fit?
It's built for a No. 10 screw or stud. The locking fork tongue slips under a loosened No. 10 terminal screw without pulling the wire out of the block, which is why electricians use it on breakers, terminal strips, and control panel blocks instead of a ring tongue.
3) Is a non-insulated locking fork terminal rated for 600 volt control and branch circuit work?
The C222M carries a 600 V rating and is UL recognized under file E9809. Because the barrel is bare copper with no insulating sleeve, the voltage rating applies in the terminated condition, so you cover the crimp with heat shrink or rely on the enclosure and terminal block shrouding for insulation.
4) Should I use a locking fork terminal or a ring terminal on a panel terminal block?
A ring terminal is the more secure choice where vibration is severe or code requires a captive connection, since the screw has to come all the way out to release it. The locking fork, like the C222M, goes on and off without removing the screw, which is what you want in a control panel with dozens of landings or anywhere you are troubleshooting and re-terminating. The locking tangs on the fork resist backing out under normal panel vibration, unlike a plain flanged spade.
5) What material is the Sta-Kon C222M terminal made of, and can I use it on aluminum conductor?
The terminal body is copper, metallic finish with no colored insulation sleeve. Copper-only barrels are intended for copper conductor; aluminum conductor needs a terminal specifically marked AL or AL9CU, so don't land aluminum in this one.
6) Do I need a special crimper for the C222M non-insulated terminal?
Yes. Non-insulated terminals are crimped with a non-insulated (open barrel or indent) die, not the color-coded insulated-terminal nest. Using a red/blue/yellow insulated die on a bare copper barrel gives an under-formed crimp. Match the tool die to the 12-10 AWG range the terminal is rated for.
7) Is the Sta-Kon C222M made in the USA?
Country of origin is the United States, which matters if you are filling a government or institutional order with domestic-content language on the PO.
8) What is the exact part number to order for the Sta-Kon 12-10 AWG No. 10 locking fork terminal?
Order Sta-Kon C222M. It's the uninsulated locking fork tongue for 12-10 AWG wire on a No. 10 stud, supplied on a belt (strip) form for use in a crimping machine or bench tool rather than loose pieces.
