Sta-Kon RBD18277 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RBD18277 female disconnect accept?
The RBD18277 is a 16-14 AWG terminal. The blue insulation is the standard color code for the 16-14 AWG range, so if you are matching terminals on a panel by color, blue barrels are your 16-14 crimps. For 22-18 AWG you need a red-coded disconnect, and for 12-10 AWG a yellow one.
2) Will this blue disconnect fit a .187 tab on a switch or relay?
Yes. The RBD18277 is a female 187 disconnect, meaning it is sized for a 0.187 inch wide male blade tab, the size commonly found on small switches, thermostats, relays and appliance controls. It will not hold properly on a 0.250 inch (1/4 inch) tab, which is the other common size on motors and larger contactors, and that calls for a female 250 disconnect instead.
3) Does a fully insulated disconnect like this need a shroud or boot added?
No. The RBD18277 is fully insulated, meaning the nylon sleeve covers the barrel and extends over the receptacle, so no separate insulating boot is required. Partially insulated disconnects leave the mating end bare and are usually paired with an add-on sleeve where live parts need to be covered.
4) What is the barrel and insulation made of on this Sta-Kon female disconnect?
Brass barrel with a nylon (polyamide) fully insulated sleeve. Nylon stands up to abrasion and higher temperatures better than vinyl, which is why it gets specified in control cabinets and under-hood style applications. Brass is the conductor body rather than tin-plated copper, so expect brass conductivity characteristics when calculating voltage drop on long low-voltage runs.
5) What crimp tool should I use on these 16-14 AWG nylon disconnects?
Use an insulated-terminal crimper on the blue (16-14 AWG) nest. Nylon insulated terminals want a controlled-cycle or ratcheting insulated crimp die rather than an open bare-terminal die, which can split the nylon sleeve. Crimp over the barrel section, then pull-test the wire before buttoning up the panel.
6) Where is the Sta-Kon RBD18277 made?
Domestic. The RBD18277 disconnect is manufactured in the United States, which matters on federal, military, and other Buy American sourced jobs where terminal origin has to be documented.
