Sta-Kon RC25177 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RC25177 male disconnect crimp onto?
The RC25177 is sized for 12-10 AWG stranded or solid copper wire. The yellow nylon insulator is the standard color code for that gauge range, so on a panel where you also have red (22-16) and blue (16-14) terminals, yellow tells the next technician the conductor size without pulling the lead. Anything smaller than 10 AWG strand count in that barrel will not crimp reliably, so step down to a blue 16-14 body for 14 gauge runs.
2) Is the Sta-Kon RC25177 disconnect UL listed, and what voltage can I use it at?
It carries UL file E66716 and is rated 300 V. That covers 120/240 V branch circuits, control wiring, and most line-voltage HVAC and appliance terminations. For anything above 300 V, use a higher-rated termination.
3) What does fully insulated mean on this male disconnect, and does it matter in a crowded panel?
Fully insulated means the nylon sleeve covers the crimp barrel and extends over the tab shank, not just the wire barrel. In a tight control cabinet or junction box where terminations sit shoulder to shoulder, that extra coverage keeps an energized tab from shorting to an adjacent lug or a grounded enclosure wall. If you need the bare tab exposed for a slide-on test probe, a non-insulated or partially insulated male disconnect is the better choice.
4) Is the RC25177 terminal brass or steel, and can I use it with copper wire?
The conductive body is brass, which is the standard pairing for copper conductors in low-voltage and line-voltage terminations. Brass avoids the dissimilar-metal corrosion you get running aluminum into a copper-only terminal, so use this one on copper wire only.
5) Do I need a special crimp tool for the Sta-Kon RC25177?
It needs a crimper with a yellow-coded 12-10 AWG nest. Nylon fully insulated terminals crimp in the insulated-terminal die set, not the bare-terminal die, because the die has to compress the barrel through the nylon without splitting it. Pliers or a non-ratcheting stamped tool will give you a loose crimp that heats up under load.
6) Is the Sta-Kon RC25177 made in the USA?
Yes, country of origin on the RC25177 is the United States. That matters on government, institutional, and Buy American specified jobs where domestic-origin electrical components have to be documented on the submittal.
7) What is the exact part number to order this yellow 12-10 male disconnect?
Order Sta-Kon RC25177. That one number covers the fully insulated nylon male .250 tab disconnect for 12-10 AWG wire in yellow, rated 300 V.
