Sta-Kon RD8-516 – Frequently Asked Questions
1) What wire size does the Sta-Kon RD8-516 ring terminal take?
The RD8-516 is built for 8 AWG conductor. It is a single-size barrel, so it won't grip 10 or 12 AWG properly and it won't accept 6 AWG at all. If you're terminating a mixed panel, order the matching terminal for each gauge rather than forcing this one.
2) Is this a copper terminal, and can I use it on aluminum conductor?
The barrel and tongue are copper, so it is intended for copper conductor. Aluminum wire needs a terminal rated AL/CU for that purpose; use a dedicated aluminum-rated lug instead of this one.
3) Is the Sta-Kon RD8-516 rated for 600 volt circuits?
The insulation on this nylon ring terminal carries a 600 V rating, which covers typical branch circuit, motor connection, and control panel work. It is also UL listed under file E9809.
4) What does the red color on this Sta-Kon terminal mean?
Red here is the insulation color on the barrel, and on Sta-Kon heavy-gauge terminals it identifies the 8 AWG size. It is a color-code aid for the installer and the inspector, not a voltage marking. Pick your crimp die by the 8 AWG size, not by assuming red means 22-16 AWG as it does on the small-gauge series.
5) What is the manufacturer part number for the Sta-Kon 8 AWG red ring terminal with a 5/16 inch ring?
Order it as Sta-Kon RD8-516. In that designation the 8 is the 8 AWG wire size and the 516 is the 5/16 inch stud size, so the adjacent numbers in the series change the ring hole while keeping the same 8 AWG barrel.
6) Does the nylon insulation on this terminal need a separate sleeve or heat shrink?
No separate sleeve is required. The nylon insulation is part of the terminal and covers the barrel to the 600 V rating. Nylon also tolerates crimp flare better than vinyl, so the barrel is less likely to split at the insulation on a heavy 8 AWG crimp.
