Sta-Kon RB3 – Frequently Asked Questions

1) What wire sizes does the Sta-Kon RB3 blue ring terminal take?
The RB3 is sized for 1.5 to 2.5 mm2 conductor, which is the blue band in the standard insulated terminal color code (roughly 16 to 14 AWG). If your conductor is smaller, around 0.5 to 1.5 mm2, you need the red size instead; above 2.5 mm2 you move to yellow. Blue insulation on these terminals is the size identifier, not just a cosmetic finish.
2) Do I need a crimping tool for the Sta-Kon RB3, or can I solder it?
It is a crimp terminal. Strip the conductor, seat it fully in the barrel so no strands are outside, then crimp with a tool and die matched to the insulated blue size range. Finish with a visual check and a gentle pull test before you bolt it down. Nothing about the terminal is supplied beyond the terminal itself, so the tool and the stud hardware come from your side.
3) Is a ring terminal better than a fork terminal for a motor stud or control panel connection?
A ring terminal is the closed-barrel choice: it goes over the stud and cannot vibrate off sideways, which is why the RB3 is used on motor terminals, junction boxes, load centers and control panel wiring. A fork or spade slides out from under a loosened nut, so it is only worth using where you expect to disconnect often and vibration is low. For machinery and distribution gear, use the ring.
4) Will the blue Sta-Kon ring terminals match the ones already in my panel?
If the existing terminals are blue insulated rings, they are the same 1.5 to 2.5 mm2 class and the RB3 keeps your panel consistent for anyone who opens it later. Colour coding on insulated terminals is standardised by wire size across brands, so a blue Sta-Kon reads the same as a blue from whatever was installed before. Stud hole size still has to match your terminal block hardware.
5) What is the barrel made of on the Sta-Kon RB3 terminal?
Electrolytic copper, with polycarbonate insulation over it. Copper is what you want against copper conductor, so there is no dissimilar-metal issue in a standard copper branch circuit or panel wire. The polycarbonate sleeve covers the barrel and gives mechanical protection at the crimp as well as the color identification.
6) Which Sta-Kon model number do I order for the blue 1.5-2.5 mm2 ring terminal?
Order model RB3. That is the single model designation for the blue polycarbonate insulated ring terminal in the 1.5 to 2.5 mm2 range, made in Sweden.
