Sta-Kon RB2257 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB2257 fork terminal accept?
The RB2257 locking fork terminal is sized for 18 to 14 AWG stranded wire, which is the blue color code band on insulated terminals. If you're terminating 16 AWG control wire or 14 AWG branch conductors, this is the right barrel size. For 22-16 AWG you need a red terminal, and for 12-10 AWG a yellow one.
2) What's the difference between a locking fork terminal and a plain spade terminal?
A locking fork has turned-up tips on the tongue that catch under the screw head, so the terminal won't slide out sideways if the screw loosens slightly from vibration. A plain spade will walk out. If you need the connection to survive vibration on panel or motor wiring and still want to slide it under a screw without removing the screw, the locking fork is the one to use. A ring tongue is more secure still, but the screw has to come all the way out to install it.
3) Are these terminals copper or aluminum, and are they insulated?
The barrel and tongue are copper, with a vinyl insulating sleeve over the crimp barrel. Copper-only means use them on copper conductors, not aluminum. The vinyl sleeve gives you strain relief and keeps the crimp barrel from shorting against an adjacent terminal in a tight panel.
4) Is the Sta-Kon RB2257 made in the USA?
Country of origin on the RB2257 is the United States, which matters if you're filling a government or federal-funded job with domestic sourcing language in the spec.
5) What part number do I order for a Sta-Kon blue #10 locking fork terminal?
Order Sta-Kon RB2257. That one number covers the 18-14 AWG, No. 10 stud, vinyl insulated locking fork configuration; there are no finish or size options to specify.
