Sta-Kon RC2227-250 – Frequently Asked Questions
1) What wire size does the Sta-Kon RC2227-250 fork terminal accept?
The RC2227-250 is sized for 12-10 AWG stranded copper conductor. The yellow vinyl insulation is the standard color code for that range, so if you are crimping 16-14 AWG you want a blue-coded terminal instead, and 22-16 AWG a red one.
2) Is this terminal rated for 600 volt control and panel wiring?
Yes. The RC2227-250 vinyl insulated fork terminal carries a 600 V rating, which covers typical motor control, panelboard, and machine-tool control wiring. It is UL recognized under file E9809.
3) What is the difference between a locking fork terminal and a plain spade or a ring terminal?
A locking fork has turned-up tangs at the tips of the fork, so once the screw is tightened the terminal cannot slip out sideways the way a plain spade can under vibration. Unlike a ring terminal, you can still slide it under a loosened screw without removing the screw entirely, which is why electricians use them on terminal strips and control panels where the screws are captive. The RC2227-250 is the locking fork style.
4) Is the barrel on this Sta-Kon terminal copper or aluminum?
Copper. The RC2227-250 uses a copper barrel under the yellow vinyl sleeve, so it is for copper conductor only. Do not crimp it onto aluminum wire, which needs a terminal specifically listed AL/CU with the proper inhibitor compound.
5) Do I need a special crimper for Sta-Kon insulated terminals?
Insulated barrel terminals in the 12-10 AWG range need a crimper with the correct color-coded nest, yellow in this case, so the barrel is compressed without cutting through the vinyl. A general-purpose plier-style crimp tool with the yellow die position will seat the RC2227-250 correctly; a bare-terminal ratchet die will not.
6) Will a 12-10 AWG fork terminal fit a #10 screw on a terminal block?
Fork terminals are sized by both wire range and stud size, and the fork opening is what has to clear your screw. The RC2227-250 covers 12-10 AWG conductor; match the fork slot to the screw diameter on your block or breaker lug before you crimp a run of them, since a slot cut for a smaller stud will not seat on a larger screw.
7) Is the Sta-Kon RC2227-250 made in the USA?
Yes, country of origin on the RC2227-250 fork terminal is the United States, which matters if you are filling a government or institutional order with domestic-content language in the spec.
