Sta-Kon RB873M – Frequently Asked Questions
1) What wire sizes does the Sta-Kon RB873M ring terminal accept?
The RB873M takes 18 to 14 AWG stranded copper wire, which is the blue color-code band on insulated terminals. If you are terminating 16 AWG control wire or 14 AWG branch conductors in a panel, this is the right barrel size. Anything heavier than 14 AWG needs the yellow 12-10 AWG range instead, and 22-16 wire belongs in a red terminal.
2) Is the Sta-Kon RB873M UL listed, and what voltage can I use it at?
It carries UL file E9809 and is rated 600 V, so it is suitable for the 120/208 and 277/480 V control and branch wiring found in panelboards and equipment enclosures.
3) Should I use a ring terminal or a fork terminal on a panelboard terminal screw?
A ring terminal like the RB873M has to come off the stud to be removed, so it cannot vibrate or pull loose sideways. That is what you want on grounding screws, motor terminals, and anything subject to vibration. A fork (spade) terminal slides out from under a loosened screw, which is faster for service work but relies entirely on screw torque. For the panelboard, wiring harness, telecom, and automotive work this terminal is intended for, the ring is the more secure choice.
4) Do I need a special crimper for the Sta-Kon RB873M?
Yes. Insulated Sta-Kon terminals are crimped with an insulated-terminal tool that compresses the barrel through the sleeve on the blue 18-14 AWG die nest. A bare-terminal or open-barrel crimper will split the nylon. The terminal itself ships without a tool, so the crimper is a separate purchase if you do not already have one.
5) Is the Sta-Kon RB873M made in the USA for a government or Buy American job?
Country of origin on the RB873M ring terminal is the United States, which is what spec writers on federally funded and institutional work usually need documented for electrical fittings.
6) Can I use the RB873M on aluminum conductors?
No. This is a copper terminal intended for copper wire in the 18-14 AWG range. Aluminum conductors require a terminal marked AL or AL9CU and the appropriate inhibitor compound.
7) What does the nylon insulation on the RB873M do that a vinyl terminal won't?
Nylon insulation is tougher and more abrasion and heat resistant than vinyl, so it holds up better when harnesses are pulled through raceways or bundled tight against each other. The RB873M is a nylon insulated ring terminal with a copper barrel, built for harness and panel work rather than one-off repairs.
