Sta-Kon RBC14-38 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RBC14-38 ring terminal accept?
The RBC14-38 is sized for 16 to 14 AWG conductors. The green nylon insulation is the color code for that range, so on a panel where crews are picking terminals by color, green means 16-14 AWG. Pair it with 18-22 AWG wire and the barrel won't grip; for heavier conductors you need a larger barrel terminal.
2) Is this terminal rated for 600 volt control and power circuits?
The RBC14-38 carries a 600 V rating and is listed under UL E9809, which covers it for standard 600 V control panels, motor terminations, and branch circuit work in commercial and industrial installations. That rating is on the insulation system, so don't strip or trim the nylon sleeve back.
3) Should I use a ring terminal or a fork/spade terminal on a 3/8 inch stud?
Use the ring style, like the RBC14-38, anywhere the connection is subject to vibration or where a loosened nut could let the conductor fall off the stud: motor leads, grounding points, busbar studs, equipment bonding. A fork or spade terminal slides off without fully removing the nut, which is convenient for frequent service on terminal blocks but is the wrong choice on a 3/8 inch power or ground stud.
4) What is the difference between a heavy-duty nylon ring terminal and a standard vinyl insulated one?
Two things separate the RBC14-38 from a common vinyl terminal. The barrel is heavy-duty, meaning thicker copper for a stronger crimp and better pull-out resistance, and the insulation is nylon rather than vinyl, so it resists abrasion, oils, and heat better and won't split as easily when the wire is flexed in a tight panel. For MRO work in equipment rooms and machine enclosures that is the one to standardize on; vinyl is fine for light-duty, low-abuse terminations.
5) Is the barrel on this Sta-Kon terminal copper, and does that matter for aluminum wire?
The barrel is copper, so the RBC14-38 is intended for copper conductors. Copper-only terminals should not be crimped onto aluminum conductors; for aluminum you need a connector specifically marked AL or AL9CU. Country of origin on this part is the United States.
6) Do I need a special crimp tool for a heavy-duty nylon insulated ring terminal?
Heavy-duty barrels like the one on the RBC14-38 need a crimper with the insulated-terminal nest sized for 16-14 AWG, typically the red/green nest on a controlled-cycle ratcheting tool. The thicker heavy-duty barrel will not fully form with a light plier-type stamped crimper, and an incomplete crimp is what shows up later as a hot connection.
