Sta-Kon RC483 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RC483 ring terminal take?
The RC483 is sized for 12-10 AWG conductors. The yellow nylon insulation is the standard color code for that gauge band, so on a panel where terminals are mixed, yellow tells you at a glance it is the 12-10 barrel and not the 16-14 (blue) or 22-18 (red). Crimp it with the die matched to the yellow range.
2) Is the RC483 terminal UL recognized, and what voltage can I use it at?
It carries UL file E9809 and is rated 600 V. That covers typical branch circuit, control panel, and motor connection work in commercial buildings. For institutional submittals, cite the UL file number along with the 12-10 AWG range.
3) Why pick a rectangular ring tongue instead of a round ring or a spade terminal?
A rectangular tongue packs tighter where terminals sit shoulder to shoulder on a crowded block, and like any ring it is a closed tongue, so the connection cannot back off the stud if the screw loosens. A spade or fork terminal can be pulled out from under a partly backed-off screw, which is why rings are the usual call on grounds and on anything that vibrates. The RC483 is the 12-10 AWG, No. 5 stud version.
4) Is the barrel on the Sta-Kon RC483 copper or aluminum?
Copper. That makes it a copper-only terminal, intended for copper conductors. If you are landing aluminum feeder wire, this is the wrong part and you want an AL/CU rated lug instead.
5) What part number do I order to match terminals already in my panel?
The manufacturer part number is RC483. If the existing terminals in the panel are yellow with a No. 5 tongue on 12-10 AWG wire, RC483 is the matching piece.
6) Does the nylon insulation on the RC483 hold up better than a vinyl terminal?
The RC483 uses nylon insulation rather than vinyl. Nylon resists abrasion and cut-through better when wires are pulled through a panel or bundled tight, and it tolerates higher temperatures, which is why it is the usual spec for control cabinets and machine wiring. Electrically it is the same 600 V rating either way.
7) Is the Sta-Kon RC483 made in the USA for domestic preference jobs?
Country of origin on the RC483 is the United States, which is what government, healthcare, and education procurement teams need when a domestic sourcing preference applies to the electrical package.
