Sta-Kon RB2257-200 – Frequently Asked Questions
1) What wire sizes does the Sta-Kon RB2257-200 fork terminal crimp?
The RB2257-200 locking fork terminal is rated for 18-14 AWG stranded copper conductors. The blue vinyl insulation is the standard color code for that 16-14 range band, so if you are terminating 12 AWG or larger you need a different (yellow) barrel size.
2) Is the RB2257-200 fork terminal rated for 600 volt control circuits?
Yes, it carries a 600 V rating, which covers typical motor control, panel, and lighting control wiring. It is UL recognized under file E9809.
3) What is the difference between a locking fork terminal and a plain spade terminal?
A locking fork has upturned tangs on the tips of the fork, so once the screw is tightened the terminal cannot vibrate free sideways the way an open spade can. You still get the advantage of a spade, which is that you can slide it under a loosened screw without removing the screw entirely, unlike a ring terminal. The RB2257-200 is the locking fork style in the 18-14 AWG range.
4) Is the barrel on this Sta-Kon terminal copper or aluminum?
Copper. That means it is for copper conductors only, not aluminum building wire, and it crimps with standard copper terminal dies.
5) Are these fork terminals made in the USA for government and institutional jobs?
Country of origin on the RB2257-200 is the United States, which is what a public-agency or federally funded project needs for domestic-content documentation.
6) What is the exact part number to order for the Sta-Kon 18-14 AWG insulated locking fork terminal?
Order Sta-Kon MPN RB2257-200. That is the vinyl insulated locking fork terminal for 18-14 AWG copper, blue insulation, 600 V.
7) Do I need a special crimper for vinyl insulated Sta-Kon terminals?
Use an insulated-terminal crimper with the die nest matched to the blue 18-14 AWG color band. A non-insulated or uninsulated-style die will cut the vinyl sleeve and ruin the strain relief on the RB2257-200.
