Sta-Kon RB727 – Frequently Asked Questions

1) Will a Sta-Kon RB727 ring terminal work on 16 AWG stranded wire?
Yes. The Sta-Kon RB727 ring terminal takes 18 to 14 AWG conductors, so 16 AWG sits in the middle of its range. Strip the wire, seat it fully in the barrel, and crimp with a tool matched to that gauge range. For 12 or 10 AWG you need a yellow-barrel terminal instead, not this blue one.
2) Is the blue Sta-Kon ring terminal rated for 600 volt control panel wiring?
Rated 600 V, which covers standard control panel, motor control center, and commercial branch circuit work. It also carries a UL listing under file E9809, which is what an inspector or institutional spec reviewer will ask for.
3) Ring terminal or fork (spade) terminal for a panel ground stud?
Use the ring. A ring terminal like the RB727 captures the 5/16 inch stud completely, so the connection cannot vibrate off if the nut loosens. A fork terminal slides out sideways and is only appropriate where you need to remove the wire without fully backing off the screw, typically on terminal blocks rather than grounding or motor studs.
4) What is the Sta-Kon RB727 terminal made of, and will it hold up in a damp mechanical room?
The barrel and ring are copper for conductivity, with a vinyl sleeve over the barrel for insulation and strain relief. Copper resists corrosion in normal indoor and mechanical room conditions. Vinyl is not a high-temperature insulation, so for engine compartments or other hot locations choose a nylon or heat-shrink insulated terminal instead.
5) What part number do I order for the Sta-Kon 18-14 AWG 5/16 inch blue ring terminal?
Order Sta-Kon RB727. That is the manufacturer part number for the vinyl insulated ring terminal covering 18 to 14 AWG with a 5/16 inch stud hole and blue insulation.
6) Can I crimp this ring terminal with pliers, or do I need a proper tool?
Use a crimper rated for insulated terminals in the 18-14 AWG range. Pliers deform the barrel without forming the conductor, and the joint pulls out or heats up under load. Strip the conductor, bottom it in the barrel, crimp, then tug-test the wire before you set the ring over the stud and torque the nut.
7) Why is this ring terminal blue, and does the color mean anything?
Blue is the industry color code for a 16 to 14 AWG insulated terminal barrel, and this one covers 18 to 14 AWG. Red is 22-18 and yellow is 12-10. On a panel build that color coding is how the next electrician confirms the right terminal went on the right conductor without reading stamped text.
8) Are Sta-Kon RB727 ring terminals made in the USA for a government job with domestic sourcing requirements?
Country of origin is the United States, which is what a government, healthcare, or education procurement file typically needs documented. It is also UL listed under file E9809 if the submittal calls for a listing reference.
