Sta-Kon RF10261 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RF10261 yellow ring terminal take?
The RF10261 is sized for 4 AWG copper wire, which is why the insulation is yellow. On nylon insulated terminals the color codes the wire range, so a yellow barrel like this one will not crimp down properly on 12 or 10 AWG, and it will not accept anything heavier than 4 AWG. Match the conductor gauge first, then the stud size.
2) Will this ring terminal fit a 1/4 inch stud or bolt?
The RF10261 ring is drilled for a No. 10 stud. A 1/4 inch bolt will not pass through it. For a 1/4 inch stud on 4 AWG wire you need a ring terminal with a 1/4 inch tongue instead.
3) Is this terminal rated for 600 volt control and panel wiring?
Yes, the Sta-Kon RF10261 carries a 600 V rating and is UL recognized under file E9809, so it is suitable for 600 V panel, control, and equipment terminations where a No. 10 stud connection on 4 AWG is called for.
4) Should I use a ring terminal or a fork terminal on a No. 10 terminal block screw?
A ring terminal like the RF10261 has a closed tongue, so the screw has to come all the way out to install or remove it, but the connection 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. For a 4 AWG feeder on equipment that sees vibration, the closed ring is the right choice.
5) What is the barrel material on the Sta-Kon RF10261, and can I use it on aluminum wire?
The conductor barrel is copper, so it is intended for stranded copper conductors. Do not use it on aluminum wire, which requires a terminal rated AL or AL/CU with the appropriate inhibitor compound.
6) Do I need a special crimp tool for this 4 AWG Sta-Kon ring terminal?
Yes. At 4 AWG this is a heavy barrel, well past the range of the small hand crimpers used for 22 to 10 AWG insulated terminals. Use a crimp tool with a die sized for 4 AWG insulated terminals. A plier crimp or an undersized die will leave a high resistance joint on a 600 V connection.
7) Does the nylon insulation on this ring terminal do anything a vinyl one does not?
Nylon insulated terminals like this yellow 4 AWG Sta-Kon resist abrasion, cut-through, and solvents better than vinyl, and the sleeve funnels the strands in during insertion. That matters in tight panel work and in MRO bins where terminals get handled rough. Electrically the rating is the same 600 V.
8) What is the country of origin on the Sta-Kon RF10261 for procurement paperwork?
The RF10261 ring terminal is manufactured in Mexico (MX). That is the value to put on origin declarations for institutional and government purchasing.
