Sta-Kon RB2253 – Frequently Asked Questions
1) What wire sizes does the Sta-Kon RB2253 fork terminal accept?
The RB2253 locking fork terminal is built for 18 to 14 AWG conductor. That is the blue color code range, and the blue nylon insulation on this terminal matches it, so a crimper with a blue die nest is the right tool. If you are landing 16 AWG control wire or 14 AWG branch wire on a screw terminal, this is the size.
2) Is the RB2253 terminal barrel copper or aluminum?
Copper barrel, so it is for copper conductor. Do not use it to terminate aluminum wire, which needs a connector specifically rated AL or AL/CU with the proper inhibitor compound.
3) What is the voltage rating on the Sta-Kon RB2253 terminal?
Rated 600 V, which puts it in range for standard commercial branch circuit and motor control wiring at 120/208/240/277/480 V. The nylon insulating sleeve is what carries that rating, so do not strip or trim it back during the crimp.
4) Is a locking fork terminal better than a ring terminal for control panel work?
A fork (spade) terminal slides under a screw head without removing the screw, which is why panel builders and service techs prefer it on terminal strips they revisit. The locking tangs on the RB2253 grip the screw shank so the terminal resists backing out under vibration, which is the usual objection to plain forks. A ring terminal is still the choice where code or spec requires a captive connection that cannot be pulled off a loosened screw, such as many ground connections.
5) Is the Sta-Kon RB2253 made in the USA?
Country of origin is the United States, which matters on public work and institutional jobs carrying Buy American or domestic-preference language.
6) How do I order the right Sta-Kon locking fork terminal, and what identifies this one?
Order by part number RB2253. That single number fixes all of it: nylon insulated locking fork, 18-14 AWG, No. 10 stud, blue. If your panel uses a different stud size or a smaller conductor, you need a different Sta-Kon part number rather than an option on this one.
