Sta-Kon RB864 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB864 ring terminal accept?
The RB864 is sized for 18 to 14 AWG stranded copper conductor. That covers the common control, fixture, and branch-circuit pigtail wire in 14 gauge down to 18 gauge signal and thermostat runs. Anything heavier than 14 AWG needs a larger barrel, typically the yellow 12-10 AWG range.
2) Is the blue insulation on this Sta-Kon terminal just color, or does it mean a wire range?
Blue is the standard AWG color code for the 16-14 band, and the RB864 is rated 18-14 AWG with blue nylon insulation. On a panel, the color tells an inspector or the next electrician the gauge range at a glance without reading the barrel stamp.
3) Why pick a nylon insulated ring terminal over a vinyl one or a spade connector?
Nylon takes more abuse than vinyl, it resists cracking when the barrel is crimped and it holds up better to heat and solvents, so it is the usual choice in motor control panels and equipment enclosures. The ring tongue, unlike a spade or fork, cannot slip off the stud if the screw backs out, which is why rings are specified on grounds and anything subject to vibration. Use a fork only where you need to pull the wire without fully removing the screw.
4) Will the RB864 terminal work on aluminum wire?
No. The RB864 barrel is copper, so it is for copper conductor only. Aluminum conductor needs a connector marked AL or AL9CU with the appropriate oxide inhibitor.
5) Is the Sta-Kon RB864 made in the USA, and does it meet spec for a government or institutional job?
Country of origin on the RB864 is the United States, which matters on Buy American and federally funded work. It is also UL listed under file E9809 and rated 600 V, which is what most institutional electrical specs call out for a terminal of this class.
6) Do I need a special crimp tool for the Sta-Kon RB864?
It is a crimp-on insulated ring terminal, so it needs an insulated-barrel crimper set to the blue 16-14 die, not a pliers or a non-insulated nest. Crimping the nylon barrel with the wrong die either cuts the insulation or leaves the conductor loose in the barrel.
7) What is the exact part number to order for the Sta-Kon 18-14 AWG No. 8 ring terminal?
Order Sta-Kon RB864. That is the manufacturer part number for the blue nylon insulated ring terminal, 18-14 AWG, No. 8 stud.
