Sta-Kon RC2203M – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RC2203M fork terminal accept?
The RC2203M is sized for 12-10 AWG stranded copper wire. The yellow insulation is the standard color code for that range, so on a panel where blue barrels are 16-14 and red are 22-18, the yellow body tells you at a glance you are on the 12-10 run. Anything smaller than 10 AWG solid or stranded will not fill the barrel properly and you should step down to a 16-14 terminal instead.
2) What screw size does the RC2203M locking fork terminal fit?
It is a No. 6 stud terminal, so it slips over a #6 screw or stud on a terminal block, breaker lug, or control device. The locking tangs on the fork grip under the screw head so the terminal will not back off the stud when the screw is loosened, which is why it is used in place of a plain spade on vibrating equipment and motor control panels.
3) Should I use a locking fork terminal or a ring terminal on a control panel?
A fork (spade) terminal like the RC2203M can be slid under a partially loosened #6 screw without pulling the screw out, which is what makes field service and re-terminations fast on a crowded terminal strip. A ring terminal is captive and cannot pull off at all, so it is the right call where code or a spec sheet requires a ring tongue on a stud. The locking tangs on this fork are the middle ground: fast to install, but resists working loose.
4) Is the Sta-Kon RC2203M UL listed?
Yes. The terminal carries UL file E9809. That is the number an inspector or a submittal package will ask for on a listed wire connector, and it applies to this nylon insulated locking fork terminal.
5) Do these Sta-Kon fork terminals come on a strip or loose?
The RC2203M is supplied in Mylar-packaged form, the tape-and-reel style packaging Sta-Kon uses for terminals fed into a bench or automatic crimping machine. If you are crimping by hand with a loose handful of terminals, order the non-Mylar version of the same part instead.
6) Is the insulation on this Sta-Kon terminal nylon or vinyl?
Nylon. The RC2203M uses a nylon insulating sleeve rather than vinyl, which holds up better to abrasion and to the heat found inside motor control and machine enclosures, and it resists splitting when the barrel is crimped. Vinyl barrels are the cheaper general-purpose option; nylon is what gets specified for industrial panel work.
7) Are Sta-Kon RC2203M terminals made in the USA?
Yes, country of origin on the RC2203M is the United States. That matters for Buy American and domestic-preference procurement on federal, municipal, and institutional projects where the electrical submittal has to document origin.
8) What is the exact part number to order this 12-10 AWG No. 6 locking fork terminal?
Sta-Kon RC2203M. One part number covers it, with no finish or size options to specify: 12-10 AWG wire range, No. 6 stud, nylon insulated, Mylar packaged.
