Sta-Kon RB863U – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB863U ring terminal crimp onto?
The RB863U takes 18 to 14 AWG stranded or solid copper wire. That is the blue color code band, and the nylon insulation sleeve is blue to match, so on a panel you can identify the gauge range at a glance without checking the stamp.
2) Why would I use a 90 degree ring terminal instead of a straight one?
The RB863U has the tongue bent 90 degrees to the barrel, so the wire comes in parallel to the mounting surface and the ring lies flat against it. That is what you want in a shallow enclosure, behind a device in a tight box, or where a straight terminal would force a sharp bend in the conductor right at the crimp. If you have depth to work with and the wire approaches the stud head-on, a standard flat ring terminal is the simpler choice.
3) Is this ring terminal rated for 600 volt control and branch circuit work?
Yes. The nylon insulated ring terminal carries a 600 V rating, which covers standard control panel wiring, motor leads, and 120/208/240/480 V branch circuit terminations.
4) Can I use this terminal on aluminum wire?
No. The RB863U barrel is copper, so it is for copper conductors only. Aluminum conductors need a terminal listed AL9CU or AL-rated with the correct compound; putting aluminum in a copper-only barrel sets up galvanic corrosion at the crimp.
5) Do I need a special crimper for the Sta-Kon RB863U?
Use an insulated-terminal crimp tool matched to the 18-14 AWG blue color code nest. Nylon insulated barrels are crimped through the sleeve, and the blue die position is what produces the correct barrel compression. A generic pliers-style crimp on the insulation alone will not hold a pull test.
6) What is the difference between nylon insulated and vinyl insulated ring terminals?
This one is nylon insulated. Nylon sleeves are tougher than vinyl, resist abrasion and cracking, and hold up better to heat and to the pull of a cable bundle, which is why they get specified for panel and machine wiring. Vinyl insulated rings are the lighter-duty option for general purpose and automotive style work.
7) Are Sta-Kon RB863U terminals made in the USA?
Country of origin on the RB863U is the United States.
