Sta-Kon RA18D – Frequently Asked Questions
1) What wire size does the Sta-Kon RA18D wristlock disconnect take?
The RA18D is sized for 22 to 18 AWG stranded wire, which is what the red insulation color signals on Sta-Kon terminals. If you are crimping 16 or 14 AWG, this is the wrong barrel and the crimp will not hold; move up to the blue (16-14) size instead.
2) Is the RA18D a male tab or a female receptacle disconnect?
The RA18D is the female half, a wristlock receptacle that slides onto a mating male tab. If you need the other side of the connection, order the matching male wristlock disconnect in the same 22-18 AWG red size so the barrel suits your conductor.
3) Is the Sta-Kon RA18D insulation nylon or vinyl, and does that matter for engine or ballast compartment wiring?
Nylon, specifically a nylon/polyamide insulating sleeve rather than PVC. That matters where the splice sees heat, abrasion, or oils, which is why nylon-insulated disconnects get specified in motor compartments, luminaire and ballast wiring, and panel harnesses over vinyl. The sleeve is red, the standard color code for the 22-18 AWG range.
4) Can I use the RA18D disconnect on solid wire instead of stranded?
Crimp disconnects like this one are intended for stranded conductors. Solid wire does not deform in the barrel the same way and tends to back out of a crimped brass barrel under vibration. For 22-18 AWG solid conductors in a fixture or control circuit, use a screw terminal or a push-in connector rated for solid wire.
5) What part number do I order to match the red 22-18 nylon wristlock disconnects already in my panel?
Order Sta-Kon RA18D. That is the manufacturer part number for the nylon-insulated wristlock disconnect in the red 22-18 AWG size, so it will match existing red wristlock terminations in the same harness.
6) What is the conductor barrel made of on the Sta-Kon RA18D?
Brass. The brass barrel is what the crimp forms around the conductor, and it is the reason this terminal needs a proper ratcheting crimp die rather than pliers, a cold-formed brass barrel only reaches its rated pull-out strength when crimped with the correct nest for a 22-18 AWG insulated terminal.
7) Are Sta-Kon RA18D terminals made in the USA?
Country of origin is the United States. That matters on federally funded and Buy American job specs, where domestic origin on electrical components has to be documented.
