Sta-Kon RA1103M – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RA1103M fork terminal take?
The RA1103M is sized for 22 to 16 AWG stranded or solid copper conductor. Red insulation is the standard color code for that range, so if you are pulling 14 AWG or heavier you need the next barrel size up, not this one.
2) What screw size does this Sta-Kon red fork terminal fit?
It is a No. 6 stud/screw fork, so it slips over a #6 terminal-block or binding screw. On a larger #8 or #10 screw the tongue opening will not seat properly on the screw shoulder, and on a smaller screw the fork can slide out from under the head.
3) Is a fork terminal or a ring terminal better for a control panel terminal strip?
A fork (spade) terminal like the RA1103M is the one to use where you want to land or pull a wire without fully removing the screw, which is most of the work on a panel terminal strip or a device screw. A ring terminal is the better choice on vibrating equipment or anywhere a captive connection is required by spec, since the ring cannot back out if the screw loosens. Same wire range, different retention.
4) Is the Sta-Kon RA1103M terminal UL recognized?
Yes. The terminal carries UL file E9809. That is what an institutional or MRO inspector will want to see cited on a panel build or a facility electrical submittal.
5) What is the barrel made of, and does it work on aluminum wire?
The barrel is copper, so it is intended for copper conductors. Do not crimp it onto aluminum wire, that pairing needs a terminal rated AL/CU with the correct inhibitor compound.
6) What does the nylon insulation with the Mylar sleeve do on this terminal?
The RA1103M uses a nylon insulating sleeve with a Mylar liner over the copper barrel. Nylon is tougher and more abrasion and crush resistant than vinyl, which is why it is the usual pick for panel and machine wiring where the harness gets flexed or pulled through tight raceway.
7) Do I need a special crimp tool for Sta-Kon insulated terminals?
Insulated nylon terminals in the 22-16 AWG range crimp with a standard insulated-terminal crimper on the red die nest. The color code on the die matches the red insulation on the terminal, so set the tool to the red position for this one. A bare-terminal or non-insulated die will cut the nylon sleeve.
8) Is the Sta-Kon RA1103M made in the USA for government and institutional orders?
Country of origin is the United States, which is what procurement needs for domestic-preference language on government, healthcare, and education purchase orders. Manufacturer part number is RA1103M.
