Sta-Kon RC1157-250 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RC1157-250 fork terminal crimp onto?
The RC1157-250 is sized for 12-10 AWG stranded copper conductors, and the yellow vinyl insulation is the standard color code for that range. If you are terminating 16-14 AWG you need a blue-coded barrel instead, and 22-18 AWG takes red.
2) What screw or stud size does this Sta-Kon fork terminal fit?
It is a No. 10 fork (spade) terminal, so it slides under a #10 screw or stud head. The open tongue means you can land it on a terminal block without pulling the screw all the way out, which is the main reason electricians choose a fork over a ring terminal.
3) Can I use a yellow 12-10 AWG fork terminal on a 600 volt control circuit?
Yes. The RC1157-250 carries a 600 V rating, which covers typical motor control, panel, and lighting circuit terminations. It is also UL recognized under file E9809.
4) Is the Sta-Kon RC1157-250 a copper terminal or aluminum?
The barrel and tongue are copper, so it is intended for copper conductors only. Do not use it on aluminum wire, which requires a terminal specifically marked AL or AL9CU along with the proper inhibitor compound.
5) Should I use a fork terminal or a ring terminal for a terminal strip?
A fork terminal like the RC1157-250 is the faster choice on a crowded terminal strip or device block: back the #10 screw off a turn or two and the tongue slips in from the side. A ring terminal is the better pick where vibration or a safety-critical connection is involved, since the closed tongue cannot back out if the screw loosens.
6) Do I need a special crimper for Sta-Kon insulated terminals?
Use a crimper matched to insulated barrels in the 12-10 AWG range, usually the yellow-marked nest on a color-coded insulated terminal tool. Pliers or an uninsulated-terminal die will crush the vinyl sleeve and leave a connection that does not hold its pull-out strength.
7) Where is the Sta-Kon RC1157-250 made?
Country of origin is the United States. For agencies and institutional buyers with domestic sourcing requirements on their purchase orders, that is the relevant data point, along with the UL E9809 recognition.
8) I need to order the exact Sta-Kon part number for a 12-10 AWG No. 10 fork terminal. What is it?
Order Sta-Kon RC1157-250. That is the manufacturer part number for the expanded-insulation vinyl fork terminal rated 12-10 AWG with a No. 10 tongue.
