Sta-Kon RB1333M – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB1333M ring terminal accept?
The RB1333M takes 18 to 14 AWG stranded or solid copper wire. That's the blue insulation code on nylon terminals, so if you're sorting a bin by color, blue is the 16-14 range band in the standard red/blue/yellow progression. Anything 12 AWG or larger needs a yellow-coded terminal instead.
2) What stud or screw size does the RB1333M ring fit?
The ring is sized for a No. 6 stud or screw. On a #8 or #10 terminal block screw the ring won't pass over the threads, so step up to a larger ring in the same 18-14 AWG family.
3) Should I use a ring terminal or a fork terminal on a terminal block?
A ring like the RB1333M has to come off the stud to be removed, which is why it's specified where vibration or an accidental pull-off is a concern: motor leads, grounds, bus studs. A fork or spade slides out from under a loosened screw, so it's faster for service work but can back out. For anything safety-related or vibrating, use the ring.
4) What is the insulation on the RB1333M made of, and does it need heat?
The barrel insulation is nylon, not vinyl and not heat shrink. Nylon takes crimping abuse better than vinyl and won't split at the barrel mouth, and no torch or heat gun is involved. You crimp it cold with the correct 18-14 AWG nest in an insulated-terminal crimper.
5) Can I use the RB1333M on a 16 AWG thermostat or control wire?
Yes, 16 AWG sits inside the 18 to 14 AWG range the RB1333M is rated for, so it crimps correctly with the blue nest on an insulated-terminal tool. Just confirm the landing point is a No. 6 stud or screw, since that's the ring size.
6) What does the mylar on the Sta-Kon RB1333M mean for installing it?
Mylar means the terminals come banded together on a mylar strip rather than loose in a bag. It keeps them oriented for strip-fed and bench crimping and keeps a run of the same gauge together on the truck. They break off individually for hand crimping.
7) Is the Sta-Kon RB1333M made in the USA for a government or institutional spec?
Country of origin is the United States, which is what a government, healthcare, or education procurement spec with a domestic-sourcing requirement will be looking for on the line item, alongside the UL E9809 file number.
