Sta-Kon RB2577F – Frequently Asked Questions
1) What wire size does the Sta-Kon RB2577F flag disconnect crimp onto?
The RB2577F takes 16-14 AWG stranded wire, which is what the blue nylon insulation signals on Sta-Kon terminals. Blue is the standard 16-14 color code, so you can sort these by sight in a panel build without pulling the part number.
2) Will the RB2577F fit a 1/4 inch male tab on a motor or relay terminal?
Yes. It is a FEM-250 female disconnect, meaning it slides onto a .250 inch (1/4 inch) wide blade tab, the size used on most relays, fan motors, switches and HVAC contactors.
3) Why use a 90 degree flag disconnect instead of a straight female disconnect?
A flag terminal brings the wire in at a right angle to the tab instead of straight off the end. That is what you want when the tab sits close to a housing wall, a motor can, or the back of a switch and there is no room for the wire to run inline. If you have depth behind the tab, a straight disconnect is simpler. The RB2577F is the 90 degree flag version in 16-14 AWG.
4) Do I need a special crimper for the RB2577F, or will my standard insulated terminal tool work?
Use an insulated-terminal crimper sized for the blue 16-14 AWG nest, the same die you would use for any nylon insulated 16-14 Sta-Kon terminal. A bare-terminal or non-insulated die will crush the nylon sleeve instead of forming the barrel properly.
5) What does open top mean on this nylon insulated disconnect?
Open top refers to the crimp barrel: the insulation sleeve is open over the wire barrel so you can see the conductor seated in the crimp before you compress it. It lets you verify strands are fully inserted rather than guessing, which matters on inspected work.
6) Is the body of the RB2577F copper or brass, and does it matter?
The conductive body is brass, with nylon/polyamide insulation over it. Nylon takes abrasion and higher heat better than vinyl, so these hold up in motor compartments and tight equipment bays where a PVC sleeve can tear on a sheet metal edge.
7) Are Sta-Kon RB2577F terminals made in the USA?
Country of origin is the United States. Useful if you are supplying a government, school, or federally funded job with domestic sourcing language in the spec.
