Sta-Kon B250M – Frequently Asked Questions
1) What wire size does the Sta-Kon B250M female disconnect crimp onto?
The B250M takes 16 to 14 AWG stranded wire, which is the range called out in its product designation (No16-14). Outside that range the barrel won't form a proper crimp, so for 22-18 AWG or 12-10 AWG you need a different barrel size in the same family.
2) Is the Sta-Kon B250M insulated, and does that matter for my application?
No insulation at all on this one, it is a bare brass terminal. That matters two ways: you have to provide your own protection where terminals sit close together or near grounded metal (heat shrink or a nylon fully insulated sleeve), and it is the right choice in high temperature spots where a vinyl or nylon sleeve would not survive.
3) Is the B250M disconnect UL recognized?
It carries UL file E66716. If your panel work or control wiring has to be built to a UL listing, that file number is what an inspector or QA reviewer will want on the submittal.
4) How is the Sta-Kon B250M packaged, and does that affect how I crimp it?
The B250M comes belted, meaning the terminals are carried on a strip for feeding into a semi-automatic or bench applicator. For hand crimping with a loose-piece tool you would want the same terminal supplied loose rather than on a belt.
5) Should I use a non-insulated female disconnect or a fully insulated one?
Go non-insulated, like the Sta-Kon B250M, when you want your own heat shrink over the joint, when the terminal has to sit in a tight stack, or where ambient heat would degrade a plastic sleeve. Choose a fully insulated or nylon-sleeved disconnect instead when the terminal is exposed in a box with other live tabs and you want the protection built in with no second step.
6) What is the Sta-Kon B250M made of?
Brass, with a plain metallic finish and no sleeve. Brass barrels crimp onto copper conductors and are standard for quick-disconnects in control and appliance wiring; they are not intended for aluminum conductors.
