Sta-Kon RC1123 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RC1123 fork terminal crimp onto?
The RC1123 is sized for 12-10 AWG stranded copper conductors. Yellow insulation is the standard color code for that range, so if you are pulling terminals out of a bin, yellow means 12-10 on this family. For 16-14 AWG you need a blue terminal and for 22-18 AWG a red one, not this part.
2) What screw size does the RC1123 fork terminal fit?
It is a No. 8 stud/screw size fork. That covers the typical No. 8 terminal screw on breakers, control blocks, and terminal strips. The open fork slips under a loosened screw without removing it, which is why these are used for retrofits and panel rework rather than ring tongues.
3) Is this Sta-Kon fork terminal UL listed?
Yes. It is covered under UL file E9809. Institutional and MRO specs that call for UL recognized/listed wire connectors can be satisfied by citing that file number.
4) Can I use this terminal on a 480 V motor control circuit?
The RC1123 carries a 600 V rating, so 480 V control and power circuits are within its voltage rating. Conductor ampacity and the device's own terminal rating still govern the connection, but the terminal itself is not the limit at 480 V.
5) Should I use a fork terminal or a ring terminal on a terminal block?
A fork (spade) terminal like the RC1123 slides in from the side, so you only back the screw out a turn or two, which is faster on a live-rework or dense terminal strip. A ring terminal has to come off the stud entirely but it cannot pull out if the screw loosens, so vibration-prone equipment and anything where a dropped connection is a safety issue is usually specified as a ring. Both land on the same No. 8 screw.
6) Is the barrel on this terminal copper or aluminum?
Copper barrel with nylon insulation. That means it is for copper conductors only, not aluminum building wire, which needs an AL/CU rated connector and antioxidant compound.
7) Do I need a special crimp tool for Sta-Kon RC1123 terminals?
Use a crimp tool matched to the yellow 12-10 AWG nest, not pliers. Sta-Kon insulated terminals are designed around a controlled indent crimp, and the yellow die position on a standard insulated-terminal crimper corresponds to the 12-10 range this part covers. A pinched or over-crimped barrel is the usual cause of a failed pull test on these.
8) Why choose a nylon insulated terminal instead of vinyl?
Nylon insulation on the RC1123 is tougher and handles higher temperatures and more abrasion than vinyl, and it resists cracking when the barrel is crimped or the wire is flexed at a panel entry. Vinyl terminals are the cheaper general-purpose option; nylon is what gets specified for industrial control panels and anything that sees heat or rough handling.
9) What is the exact part number and is it made in the USA?
