Sta-Kon RB485 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB485 ring terminal crimp onto?
The RB485 is sized for 16-14 AWG conductors. That is the blue band in the standard insulated terminal color code, and the terminal's insulation is blue to match. Run 12 AWG or 18 AWG on the same job and you need a different barrel size, not this one.
2) What stud or screw size does the RB485 ring fit?
The ring is sized for a No. 4 stud or screw, which is the smallest common terminal block and appliance screw size. If your lug screw is a #6, #8 or 1/4-20, this ring tongue will slip over nothing or not seat properly, so step up to the matching ring size instead.
3) Is this ring terminal rated for 600 volt control and power circuits?
Yes. The Sta-Kon RB485 carries a 600 V rating, so it is usable on standard commercial control panels, motor control wiring and lighting circuits up to that voltage.
4) Is the Sta-Kon RB485 UL listed for panel and inspection work?
It is built to UL file E9809, which is what an inspector or a spec writer looking for a listed termination on a 600 V circuit wants to see on the submittal.
5) Why choose a rectangular tongue ring terminal instead of a round one or a spade?
The rectangular tongue is narrower across the body than a standard round ring, so it fits tight terminal blocks and crowded strips where round tongues overlap each other. Unlike a spade or fork, it is a closed ring, so the connection cannot vibrate off the stud without backing the screw all the way out. Use the RB485 where you need that captive connection on a No. 4 screw in limited space.
6) Is the barrel on this blue terminal copper or aluminum, and can I use it on aluminum wire?
The conductor barrel is copper. That makes it a copper-only termination, intended for stranded or solid copper conductors in the 16-14 AWG range. Aluminum branch conductors need an AL/CU rated connector, not this terminal.
7) What part number do I order and what crimp tool do I need?
Order by manufacturer part number RB485. It is a crimp terminal, so it needs a crimp tool matched to the blue 16-14 AWG die, not pliers; the terminal itself ships bare with no hardware, so the No. 4 screw or stud comes from the equipment you are landing on.
8) Does the nylon insulation on the RB485 hold up better than vinyl sleeves?
The sleeve is nylon rather than vinyl. Nylon insulated barrels resist abrasion and crush better when wire bundles get pulled through panels, and they hold their shape better at elevated temperature than a vinyl sleeve. It is the usual pick for panel and MRO stock where terminals get handled rough.
9) Is the Sta-Kon RB485 made in the USA for buy-American jobs?
Country of origin on the RB485 is the United States, which matters on government, institutional and federally funded work where domestic sourcing is written into the spec.
