Sta-Kon RB8 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB8 blue ring terminal crimp onto?
The RB8 ring terminal is sized for 1.5 to 2.5 mm2 conductor, which is the 16 to 14 AWG range in US gauge terms. That is also why the barrel insulation is blue: blue is the standard color code for the 16-14 AWG terminal size, so an electrician can confirm the right terminal at a glance on the panel.
2) My wire is 18 AWG. Will the Sta-Kon RB8 still crimp reliably?
No, not on its own. The RB8 barrel is sized for 1.5 to 2.5 mm2 (16 to 14 AWG). An 18 AWG conductor sits loose in that barrel and the crimp can pull out. Use a red terminal sized for 0.5 to 1.5 mm2 (22 to 16 AWG) instead, or double the conductor back on itself only if your spec permits it.
3) Can I use the Sta-Kon RB8 with a standard insulated terminal crimp tool?
Yes. The RB8 is an insulated ring terminal in the blue (1.5 to 2.5 mm2 / 16-14 AWG) size class, so it crimps with the blue die or nest on any standard color coded insulated terminal crimper. Use the blue station, not the red (22-16) or yellow (12-10) one, or the barrel will be over or under compressed.
4) Is the Sta-Kon RB8 insulation nylon or polycarbonate, and does that matter?
It is polycarbonate, not vinyl or nylon. Polycarbonate sleeves are rigid rather than soft, so they hold their shape in the crimp and resist cracking better than vinyl when the terminal is flexed or installed in colder conditions. If your spec calls out a vinyl insulated ring terminal specifically, this is a different insulation material.
5) Should I use a ring terminal like the RB8 or a spade terminal on my control panel?
A ring terminal such as the RB8 is the closed type: the screw passes through the ring, so the connection cannot pull off the stud if the screw loosens. That is the choice for vibration, motors, battery and ground studs, and anywhere a dropped conductor is a safety issue. A spade (fork) terminal slides out from the side and is faster to swap on dense terminal strips, but it will walk off a loose screw. Many panel and UL specs require the ring style on grounding points for that reason.
6) What is the Sta-Kon RB8 terminal made of, and will it corrode on a copper conductor?
The barrel is electrolytic copper, so it is matched to copper conductor with no dissimilar metal junction at the crimp. Do not use it on aluminum conductor, which needs a terminal rated AL or AL/CU with the proper inhibitor compound.
7) What is the exact part number and origin for the Sta-Kon blue polycarbonate ring terminal?
Order it as Sta-Kon RB8. It is manufactured in Sweden. For MRO buyers standardizing a crib, the RB8 covers the blue 1.5 to 2.5 mm2 band of a ring terminal assortment.
