Sta-Kon RC2223M – Frequently Asked Questions
1) What wire size does the Sta-Kon RC2223M fork terminal take?
The RC2223M locking fork terminal is sized for 12 to 10 AWG conductors. The yellow nylon insulation is the standard color code for that range, so if you are crimping 16-14 AWG (blue) or 22-16 AWG (red), this is the wrong barrel and the crimp will not hold.
2) What screw or stud size does the Sta-Kon RC2223M fit?
It is built for a No. 10 screw or stud. The fork is the locking type, so the tongue tines grip under the screw head instead of sliding straight out, which is what you want on vibrating equipment or a terminal strip you service often.
3) Can I use a nylon insulated locking fork terminal on a 480V motor circuit?
Yes. The RC2223M carries a 600 V rating, which covers 120/208, 277 and 480 V control and power work. The insulation is nylon, which holds up better to abrasion and pull-through than vinyl on a crowded panel.
4) Is the Sta-Kon RC2223M UL listed, and where is it made?
It is covered under UL file E9809, which is what an inspector or a spec writer on an institutional job will ask for. Country of origin is the United States.
5) Why choose a locking fork terminal instead of a ring terminal?
A fork (spade) terminal like the RC2223M slides in under a screw you only have to back off, so you can add or pull a conductor without removing the screw and the devices stacked on it. A ring terminal has to come off over the screw head, which means disassembly. The locking tines on this one close the usual gap in fork terminals, which is that a plain spade can walk out under vibration. Use a ring where a closed loop is specified or required.
6) Is the barrel on this Sta-Kon terminal copper or aluminum?
Copper. That makes it a match for copper conductors in the 12-10 AWG range; it is not a listed connector for aluminum building wire, which needs an AL/CU rated connector and compound.
7) Do I need a special crimper for the Sta-Kon RC2223M?
Use a crimper sized to the yellow 12-10 AWG nest. Insulated-barrel terminals are crimped over the insulation sleeve, so a dedicated insulated-terminal tool with color-coded dies gives the repeatable crimp a UL listed connection depends on. A bare-terminal or open-barrel die will cut the nylon.
8) What is the exact part number to order this Sta-Kon yellow fork terminal?
Order Sta-Kon RC2223M. That is the manufacturer part number for the nylon insulated locking fork terminal, 12-10 AWG, No. 10 stud.
