Sta-Kon RB863 – Frequently Asked Questions
1) What wire size does the Sta-Kon RB863 ring terminal take?
The RB863 is sized for 18-14 AWG conductors. That blue insulation is the standard color code for the 16-14 AWG range, so if you are terminating 12 AWG or larger you need a yellow-bodied terminal instead, not this one.
2) Will the Sta-Kon RB863 fit a #8 stud or screw?
Yes, the ring tongue is drilled for a No. 8 bolt or stud. It will slip over a #6 as well, though you will want a washer to keep the smaller head from pulling through the tongue.
3) Is the RB863 ring terminal UL listed, and what voltage is it good for?
It carries UL file E9809 and is rated 600 V, which covers standard commercial branch circuits, control panels, and motor terminations.
4) Should I use a ring terminal like the RB863 or a spade/fork terminal?
Use the ring when the connection is on a stud or a terminal screw that carries vibration or load, a motor lead, a grounding lug, a panel bus. The ring cannot back off the stud if the nut loosens. A fork terminal slides out from under a partly loosened screw, which is why many panel and control specs call for rings on anything that matters. Trade-off is you have to fully remove the nut to land a ring; a fork goes on with the screw just backed off.
5) What is the Sta-Kon RB863 made of, and can I use it on aluminum wire?
The barrel is copper with a nylon insulating sleeve, so it is for copper conductors only. Aluminum wire needs a terminal marked AL or AL/CU with the appropriate inhibitor compound.
6) Do I need a special crimper for Sta-Kon RB863 terminals?
Use a crimper matched to insulated terminals and set to the blue (18-14 AWG) die position. A standard insulated-terminal tool indexes by color, so the blue nest is the one for this terminal. Pliers or an uninsulated-die crimper will crush the nylon and leave you with a connection that pulls out.
7) Why choose a nylon insulated terminal over a vinyl one?
Nylon takes a higher operating temperature and resists abrasion, cut-through, and oils better than vinyl, which matters in motor control cabinets, engine compartments, and anywhere the harness gets handled. The nylon sleeve on the RB863 also funnels the strands in, so you get fewer stray wires at the barrel mouth during crimping.
8) Where is the Sta-Kon RB863 manufactured?
It is made in the United States, which is what government, transit, and federally funded jobs with domestic content requirements need to see on the submittal.
