Sta-Kon RA873M – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RA873M ring terminal take?
The RA873M is sized for 22 to 16 AWG stranded copper conductor. The red nylon insulation is the industry color code for that range, so if you are pulling 14 AWG you need a blue 16-14 barrel instead, not this one.
2) Is this Sta-Kon terminal rated for 600 volt control panel wiring?
Yes. The RA873M carries a 600 V rating and is UL recognized under file E9809, which covers panelboard and control wiring terminations as well as wiring harness, telecom, and automotive work.
3) Should I use a ring terminal or a fork terminal on my terminal strip?
Use the ring, like the RA873M, where the connection cannot be allowed to back out under vibration: the closed No. 10 tongue is captive and the screw has to come all the way out to release it. A fork or spade is faster to service because it slides out under a loosened screw, but on vibrating equipment or a ground stud the ring is the right call.
4) Is the barrel on this nylon insulated ring terminal copper or aluminum?
Copper barrel with nylon insulation. That means it is for copper conductor only, not aluminum, and it needs a crimp tool matched to insulated terminals in the 22-16 AWG range.
5) Do these ring terminals meet a Buy American or domestic sourcing requirement?
Country of origin on the RA873M is the United States, which is what most government, healthcare, and institutional procurement specs are asking for when they call out domestic content on wiring accessories.
6) What is the difference between nylon insulated and vinyl insulated ring terminals?
Nylon, which is what the RA873M uses, holds up better to abrasion and to higher operating temperature than vinyl, and it resists cracking when the barrel is crimped. Vinyl is the cheaper choice for benign indoor harness work. For automotive and panel terminations where the lead gets flexed or dressed into a bundle, nylon is the one to spec.
7) Can I order the Sta-Kon RA873M by part number?
Yes, RA873M is the manufacturer part number and it is the single configuration offered: red nylon insulated ring, 22-16 AWG, No. 10 stud.
