Sta-Kon RB482 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB482 ring terminal crimp?
The RB482 is sized for 16-14 AWG conductors, which is the blue color code band on insulated terminals. Run it on 12 AWG and the barrel won't close on the strands; drop to 18-16 AWG and you need the red 22-16 size instead. The blue nylon insulation is how an electrician spots the right size in a mixed bin.
2) What stud or screw size does the RB482 ring fit?
It's a No. 8 ring, so it drops over a #8 stud or machine screw on a terminal block, lug pad, or ground screw. A #10 stud won't pass through the tongue.
3) Is this ring terminal rated for 600 volt control and branch circuit work?
Yes, the RB482 carries a 600 V rating and is UL recognized under file E9809, which covers it for typical control panel, motor connection, and branch circuit terminations.
4) Should I use a rectangular ring terminal or a fork/spade terminal on a terminal block?
A ring tongue like the RB482 has to come off the stud to be removed, so it can't vibrate loose or slip sideways off the screw. That's why panel builders and equipment MRO specs call for rings on anything that moves or matters. A fork terminal installs without pulling the screw all the way out, which is faster for frequent service work but less secure. The rectangular tongue shape on the RB482 also packs tighter side by side on a crowded terminal strip than a round tongue of the same ring size.
5) Is the barrel on the RB482 copper or aluminum, and can I use it on aluminum building wire?
The conductor barrel is copper, so it's for copper wire only. Aluminum conductors need a terminal specifically marked AL or AL9CU with the appropriate inhibitor compound; a copper-only barrel on aluminum wire is a code violation and a long-term failure point.
6) Can I crimp the RB482 with a generic plier-style crimper?
Sta-Kon insulated terminals are designed around a controlled-cycle insulated crimp. A cheap plier crimper will often deform the nylon sleeve and under-compress the barrel, which is what causes high-resistance joints that show up later as heat. Use a crimp tool rated for insulated 16-14 AWG terminals and pull-test the first one.
7) Does the nylon insulation on the RB482 hold up better than vinyl?
Nylon is the tougher of the two common insulation sleeves on crimp terminals, resisting abrasion and cut-through when wire bundles are pulled through a panel or conduit body, and it holds its shape better at elevated temperature than vinyl. The RB482 uses a nylon sleeve in blue.
8) Are Sta-Kon RB482 terminals made in the USA for buy-American project specs?
Country of origin on the RB482 is the United States, which is what institutional and government procurement needs on record when a job carries domestic sourcing language.
