Sta-Kon RBC857 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RBC857 ring terminal crimp onto?
The RBC857 is sized for 16-14 AWG stranded copper conductor. Blue insulation is the standard color code for that range, so you can confirm the gauge at a glance on a crowded panel. If you are on 22-16 AWG, you need a red-coded terminal instead; for 12-10 AWG, a yellow one.
2) What stud or screw size does the RBC857 ring fit?
The ring is a No. 6 size, so it drops over a #6 screw or stud, the size you see on most control terminal blocks, small motor terminals, and ground screws. A larger stud needs a bigger ring, since the tongue hole will not stretch.
3) Is a ring terminal like the Sta-Kon RBC857 better than a fork terminal for my connection?
Use the ring when the connection cannot be allowed to back off the stud. A ring is a closed tongue, so it stays captive even if the screw loosens, which is why it is preferred for vibration, grounding, and anything that gets inspected. A fork or spade slips off under a loosened screw, but it lets you service the wire without fully removing the hardware. For a #6 stud carrying 16-14 AWG, the RBC857 is the captive option.
4) Is the Sta-Kon RBC857 terminal copper, and will it work on aluminum wire?
The barrel is copper, so it is intended for copper conductor only. Aluminum wire needs a terminal marked AL or AL9CU with the appropriate inhibitor compound. Pairing a copper-only barrel with aluminum invites galvanic corrosion and a high-resistance joint.
5) Do I need a special crimper for the Sta-Kon RBC857?
Use a crimp tool with a die matched to insulated 16-14 AWG terminals, the blue nest on a standard color-coded insulated crimper. The vinyl sleeve is crimped along with the barrel, so an uninsulated or open-barrel die will split it. Pliers are not an acceptable substitute if the UL rating is meant to hold.
6) Is the Sta-Kon RBC857 made in the USA for Buy American projects?
Country of origin is the United States, which is what a government, school district, or federally funded job needs on record for domestic content requirements.
7) What is the heavy-duty version of this Sta-Kon ring terminal, and why does it matter?
Heavy-duty means a thicker barrel and tongue than the standard vinyl ring in the same 16-14 AWG range. The practical difference is on the job: the barrel tolerates a harder crimp and the tongue resists deforming when the #6 nut is torqued down, which matters on equipment that vibrates or gets re-terminated.
8) What is the manufacturer part number to order this Sta-Kon blue ring terminal?
Order it as Sta-Kon RBC857. That is the single catalog number for the blue vinyl insulated heavy-duty ring terminal, 16-14 AWG, No. 6 stud.
