Sta-Kon 14RB-516 – Frequently Asked Questions

1) Will a Sta-Kon 14RB-516 ring terminal work on 16 AWG stranded wire?
Yes. The Sta-Kon 14RB-516 blue vinyl insulated ring terminal is rated for 18 to 14 AWG conductors, so 16 AWG sits in the middle of its range. The blue insulation is the standard color code for that wire range, which is how an inspector or the next tech reads the barrel without pulling it apart.
2) Is this ring terminal rated for 600 volt control panel wiring?
The 14RB-516 carries a 600 V rating and is UL listed under file E9809, which covers the typical 480 V and 600 V control panel and motor control center work this terminal gets used for.
3) Ring terminal or fork terminal for a 5/16 inch grounding stud?
Use the ring. A closed ring like the Sta-Kon 14RB-516 has to have the nut removed to come off the 5/16 inch stud, so it stays put under vibration, which is why ground and bonding points and motor terminals are normally ringed. A fork or spade slides out sideways under a loosened nut and is only worth using where you expect to disconnect the lead often and vibration is not a factor.
4) Do I need a special crimp tool for Sta-Kon insulated terminals?
Yes, use an insulated-barrel crimper sized for the 18-14 AWG (blue) range. The vinyl sleeve on the 14RB-516 is crimped through along with the copper barrel, so a bare-terminal or open-barrel die will cut the insulation or leave a loose crimp. The blue nest on a color-coded insulated crimper matches this terminal.
5) Is the barrel on this Sta-Kon terminal copper or aluminum, and can I use it on aluminum conductors?
The barrel is copper, so it is for copper conductors only. Crimping copper hardware onto aluminum wire creates a dissimilar-metal joint that corrodes and loosens; aluminum branch or feeder conductors need an AL/CU rated connector with the proper compound instead.
6) What is the exact part number to order for the blue 5/16 inch Sta-Kon ring terminal?
Order Sta-Kon 14RB-516. The 14 refers to the 18-14 AWG wire range, RB is the blue vinyl insulated ring, and 516 is the 5/16 inch stud size.
7) Is the Sta-Kon 14RB-516 made in the USA?
Yes, country of origin is the United States. That matters on public and institutional jobs carrying domestic-sourcing requirements, where terminals and connectors get counted along with everything else in the panel.
