Sta-Kon RA486 – Frequently Asked Questions
1) What stud or screw size does the Sta-Kon RA486 ring terminal fit?
The RA486 is a No. 4 rectangular ring tongue, so it lands on a #4 stud or screw. The rectangular tongue shape is useful on crowded terminal blocks and small breaker or device screws where a round tongue would overlap the neighboring terminal.
2) Is the Sta-Kon RA486 terminal rated for 600 volt control and power circuits?
Yes, it carries a 600 V rating, which covers typical commercial control panels, motor control circuits, and line voltage device terminations. It is also UL recognized under file E9809, which matters if an inspector or a facility spec calls for UL components on the termination.
3) Is the RA486 barrel copper or aluminum, and can I use it on copper building wire?
The barrel is copper, so it is intended for copper conductors. Do not use it on aluminum wire, which needs a lug marked AL or AL9CU with the appropriate inhibitor compound.
4) What is the difference between a nylon insulated terminal like the Sta-Kon RA486 and a vinyl insulated one?
Both are crimp ring terminals, but the RA486 uses a nylon insulating sleeve rather than vinyl. Nylon is the tougher choice where the harness gets pulled, flexed, or runs warm, and it resists abrasion and solvents better than vinyl. Vinyl is the lower cost option for cooler, static panel work. Either way the crimp itself is what carries the connection, so use the die matched to the barrel.
5) Do I need a ring terminal or will a fork terminal work on my panel screws?
A ring terminal like the RA486 is a closed tongue, so the screw has to come all the way out to install or remove it, but it cannot vibrate off the stud. A fork or spade tongue slides in under a loosened screw, which is faster for service work but can back out under vibration. For permanent panel, motor, and control terminations where nothing should walk off the screw, the closed No. 4 ring is the right pick.
6) Why is the Sta-Kon RA486 ring terminal red, and does the color mean anything?
Red is the insulation color on the RA486, and on insulated crimp terminals color is the installer's quick visual code for the wire range the barrel is sized to. On a panel it lets the next electrician confirm at a glance that the right barrel went on the right conductor without pulling the lug off the stud.
7) Is the Sta-Kon RA486 made in the USA for jobs with domestic sourcing requirements?
Country of origin on the RA486 is the United States, which is the answer a government, institutional, or federally funded project needs when domestic preference language is in the purchase order.
8) What is the correct Sta-Kon part number to order for a No. 4 red insulated rectangular ring terminal?
Order it as Sta-Kon RA486. That is the manufacturer part number for the red nylon insulated rectangular ring terminal with the No. 4 tongue.
