Sta-Kon RF4-516 – Frequently Asked Questions
1) Is the barrel on this ring terminal copper or aluminum?
Copper. That makes the RF4-516 a copper-conductor terminal, so use it on copper 4 AWG wire. Aluminum feeders need an AL/CU rated connector instead, not this one.
2) Does the RF4-516 ring terminal have a UL file number for inspection submittals?
It is listed under UL file E9809. That is the number an inspector or a spec reviewer on an institutional or healthcare job will want cited for the termination.
3) Should I use a ring terminal or a spade terminal on a 5/16 inch panel stud?
On power connections at 4 AWG, a ring is the better choice because it cannot vibrate off the stud if the nut backs off, which a fork or spade can. Use a spade only where you need to drop the lead off without fully removing the nut. The RF4-516 is the ring version in the 4 AWG, 5/16 inch stud size.
4) Does the nylon insulation on the Sta-Kon RF4-516 need extra heat shrink over the crimp?
No added sleeving is required for insulation. The nylon body already covers the barrel and provides the insulated termination at 600 V. Installers sometimes add adhesive-lined shrink over the wire entry for strain relief in high-vibration or wet locations, but that is an add, not a requirement of the terminal.
