Sta-Kon RB1157 – Frequently Asked Questions

1) What wire gauge does the Sta-Kon RB1157 fork terminal take?
The RB1157 is sized for 18-14 AWG wire, which is the blue color code band on insulated terminals. If you are crimping 16 AWG control wire or 14 AWG branch wire, this is the right barrel. Anything 12 AWG or larger needs a yellow 12-10 AWG terminal instead, and 22-18 AWG stranded needs a red barrel.
2) Will this blue fork terminal fit a #10 screw on my terminal block?
Yes. The fork (spade) opening on the RB1157 is made for a #10 stud or screw. Because it is a fork and not a ring, you can slide it under a partly backed-off #10 screw without pulling the screw all the way out, which is why panel and control-panel techs prefer them on crowded terminal strips. For connections subject to vibration, use a ring tongue instead, since a fork can back out if the screw loosens.
3) Is the Sta-Kon RB1157 rated for 600 volt control panel wiring?
Rated 600 V, so it covers standard commercial and industrial control panel and motor control center wiring as well as residential branch circuits. The insulation is vinyl, which is the general-purpose jacket; for high-heat locations near motors or ballasts, a nylon-insulated terminal holds up better.
4) Is this terminal UL listed for code-compliant electrical work?
The Sta-Kon vinyl insulated fork terminal carries UL file E9809, which is the listing an inspector or spec writer looks for on an insulated crimp terminal. It is also made in the United States, which matters on Buy American and domestic-content jobs for government and institutional work.
5) How many fork terminals come in a pack, and is this a bulk buy?
The Sta-Kon RB1157 is sold as a 1000-piece pack, which is how MRO and panel shops buy a single-gauge, single-stud-size terminal they go through constantly. If you only need a handful of #10 forks for one repair, this quantity is more than a service call calls for.
6) Do I need a special crimper for Sta-Kon insulated terminals?
Insulated crimp terminals like the RB1157 are installed with an insulated-terminal crimping tool that compresses the barrel through the vinyl sleeve; the color-coded die nest matching blue is the one to use for the 18-14 AWG range. Do not use an uninsulated-terminal die or pliers, since that cuts the sleeve and leaves a loose crimp. The terminal ships without a tool.
7) What material is the RB1157 terminal, and will it hold up in a damp mechanical room?
The barrel and tongue are copper, so you get low resistance at the crimp and good corrosion resistance for indoor panel and equipment work. Copper also means it mates properly with copper conductors with no dissimilar-metal issue at the crimp.
8) Can I use these fork terminals for equipment grounding connections?
Yes, grounding terminations on equipment and enclosures are one of the listed uses for this terminal, provided the ground conductor falls in the 18-14 AWG range and the ground screw is a #10. It is copper and UL E9809 listed, so it suits panel, distribution, and motor control center grounding points.
