Sta-Kon RC257M – Frequently Asked Questions
1) What wire size does the Sta-Kon RC257M female disconnect crimp onto?
The RC257M is sized for 12-10 AWG stranded copper conductors. The yellow vinyl barrel is the standard trade color code for that 12-10 range, so on a panel where blue barrels are 16-14 and red are 22-18, yellow tells an inspector at a glance which gauge went in. Crimp it with the yellow die station on your terminal tool.
2) Is the Sta-Kon RC257M a fully insulated terminal or do I need extra sleeving?
It comes fully insulated with a vinyl sleeve over the barrel, so no heat shrink or separate boot is needed for a standard low voltage control or appliance connection. Vinyl insulation is not a high temperature material, so for connections sitting against hot surfaces, such as heater elements or furnace burner boxes, use a nylon or ceramic bodied terminal instead.
3) Is the Sta-Kon RC257M UL listed for electrical work?
It carries UL file E9809. That is what an institutional or MRO inspector wants to see on terminations inside listed equipment and control panels, so the RC257M can be specified where UL recognized wire terminations are called for.
4) Are these Sta-Kon female disconnects made in the USA?
Yes, the RC257M is manufactured in the United States. That matters on government, military, and federally funded institutional jobs where domestic sourcing is written into the purchase terms.
