Sta-Kon RB14-8X – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB14-8X ring terminal accept?
The RB14-8X takes 18 to 14 AWG stranded copper wire. Blue is the standard color code for that range, and this terminal's insulation is blue, so it matches the rest of a crimp kit for that gauge band. Anything 12 AWG or larger needs a different barrel size.
2) What stud or screw size does the RB14-8X ring fit?
The ring is sized for a No. 8 bolt or screw stud. If your terminal block, ground lug, or motor stud is a #10 or 1/4-20, the ring will not pass over it and you need the next ring size up in the same 18-14 AWG family.
3) Is a nylon insulated ring terminal rated for 600 volt control and panel wiring?
Yes. The RB14-8X carries a 600 V rating and is UL recognized under file E9809, which covers it for typical 120/208/240/480 V control panel and motor connection work.
4) Should I use a ring terminal or a fork/spade terminal on a panel terminal block?
A ring terminal like the RB14-8X fully captures the No. 8 stud, so the wire cannot back out if the screw loosens. That is why rings are specified for vibration-prone equipment, motor leads, and grounding. A fork terminal slips on and off without removing the screw, which is faster for service work on dense terminal strips but is not a captive connection. For anything on a machine, a pump, or a ground point, use the ring.
5) Is the barrel on this Sta-Kon terminal copper or aluminum?
Copper barrel with nylon insulation. That means it is for copper conductors only, not aluminum building wire, which requires an AL/CU rated connector. The nylon sleeve holds up to abrasion and solvents better than a vinyl insulated terminal, which is why it gets specified for machine tool and panel work.
6) Do I need a special crimper for the RB14-8X, or will my general purpose tool work?
It is a Sta-Kon insulated barrel terminal, so it crimps with a standard insulated-terminal crimp die in the blue (18-14 AWG) nest. A bare-terminal or open-barrel die will crush the nylon sleeve and give you a connection that does not hold the stated rating. No solder or heat is needed.
7) Is the Sta-Kon RB14-8X made in the USA for a Buy American job?
Country of origin on the RB14-8X is the United States, which is what a government, healthcare, or transit project with domestic sourcing language in the spec will be looking for on the submittal.
