Sta-Kon RC1254 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RC1254 fork terminal crimp onto?
The RC1254 is sized for 12-10 AWG stranded copper wire, and the yellow nylon insulation is the standard color code for that gauge range. Run it on 14-16 AWG and the barrel won't grip; step down to a blue (16-14 AWG) terminal for that wire.
2) What size stud or screw does this flanged fork terminal fit?
It is built for a No. 10 stud or screw. The fork (spade) tongue slides in under a loosened No. 10 terminal screw without pulling the screw all the way out, and the flanged tongue ends resist slipping back out under vibration the way a plain spade can.
3) Is this terminal rated for 600 volt control and motor circuits?
Yes, the RC1254 carries a 600 V rating, which covers typical 120/208/240/480 V control panel, motor starter, and terminal strip work. It is UL recognized under file E9809.
4) Should I use a flanged fork terminal or a ring terminal on a terminal block?
Pick the fork when you need to service the connection without removing the screw, which is most terminal block, contactor, and device landing work. The flange on this one keeps the tongue from walking off the screw. If the circuit sees heavy vibration or a code requirement for a captive connection (many motor and grounding terminations), use a ring terminal of the same 12-10 AWG and No. 10 stud size instead, since the screw has to come out and that is what holds it captive.
5) Is the barrel on the RC1254 copper or aluminum, and can I put it on aluminum wire?
The conductor barrel is copper, so use it on copper conductors only. Aluminum building wire needs a terminal rated AL/CU; a copper-only crimp on aluminum will corrode and loosen at the joint.
6) Is the Sta-Kon RC1254 made in the USA for a Buy American job?
Country of origin on the RC1254 is the United States, which is what a government, school, or transit submittal typically needs documented for terminations.
7) Does the nylon insulation hold up better than vinyl in a hot panel?
The sleeve on this fork terminal is nylon rather than vinyl. Nylon tolerates higher temperatures and resists abrasion and cut-through when wires are pulled through a crowded enclosure, which is why it's the usual spec for panel and MRO work. It also funnels the strands during insertion, so you get fewer stray wires outside the barrel.
8) What part number do I order and are there other options to pick?
There's one configuration: Sta-Kon model RC1254, the yellow nylon insulated flanged fork terminal for 12-10 AWG on a No. 10 stud. No finish, size, or color choices to specify.
