Sta-Kon RC480 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RC480 ring terminal accept?
The RC480 is built for 12-10 AWG conductors, which is the yellow color code band on insulated terminals. If you're terminating 16-14 AWG you'll crimp loose and the connection will pull out, so step down to a blue-coded terminal for that range.
2) Is the RC480 rated for 600 volt control and branch circuit work?
The RC480 carries a 600 V rating and is UL recognized under file E9809, so it's suitable for 600 V control panels, motor connections, and branch circuit terminations within that voltage.
3) Why choose a rectangular ring terminal instead of a round ring or a fork terminal?
A rectangular ring tongue gives a flat, wider contact face and seats squarely against a terminal block without rotating, which matters in tight rows of screws. A standard round ring works the same electrically but can spin under the screw. A fork (spade) terminal slides in without removing the screw, which is faster for service work, but it can back out under vibration where a closed ring cannot.
4) Is the RC480 terminal barrel copper or aluminum?
Copper. The RC480 uses a copper barrel, so it is for copper conductors only. Aluminum wire needs an AL/CU rated connector with inhibitor compound, not this terminal.
5) What does the nylon insulation on the RC480 do versus a vinyl insulated terminal?
The RC480 uses a nylon insulating sleeve over the barrel. Nylon is tougher than vinyl, resists abrasion and splitting when the terminal is flexed or pulled through a panel, and holds up better to heat during crimping. The yellow sleeve also identifies it as the 12-10 AWG size at a glance in a panel.
6) Is the Sta-Kon RC480 made in the USA for government or institutional specs?
The RC480 ring terminal is manufactured in the United States, which is what Buy American and domestic-preference procurement language on government, healthcare, and education jobs usually asks for.
7) Do I need a special crimper for the RC480 insulated ring terminal?
Crimp it with a tool matched to insulated barrel terminals in the 12-10 AWG range, using the yellow-coded die nest. A bare-terminal or general purpose plier-style crimp will crush the nylon sleeve and under-form the barrel. Terminals are supplied loose, so no strip or reel feed tooling applies.
