Sta-Kon A250-TB – Frequently Asked Questions
1) What wire size does the Sta-Kon A250-TB female disconnect crimp onto?
The A250-TB takes 22 to 18 AWG stranded or solid copper wire. If you're terminating 16 or 14 AWG, this is the wrong barrel size, you need the next range up in the same .250 tab family.
2) Is this disconnect insulated, and does that matter in a crowded junction box?
No insulation at all, it's a bare brass terminal. Once crimped, the barrel and the receptacle body are live and exposed, so you need to slide on a nylon or vinyl sleeve or heat shrink, or keep the terminal well clear of grounded metal. In tight control enclosures a fully insulated disconnect is the easier choice.
3) Why pick a non-insulated disconnect over a vinyl or nylon insulated one?
Two reasons: heat and space. With no plastic body, the bare brass terminal survives higher-temperature spots such as furnace and heater terminal blocks where a vinyl sleeve would soften, and it lets you add your own heat-shrink for the exact clearance you want. If the terminal sits in a panel where an accidental touch is possible, go insulated instead.
4) Is the Sta-Kon A250-TB UL recognized?
It carries UL file E66716. Useful if you're submitting an electrical panel or control assembly for inspection and need the terminations traceable to a UL file.
5) Do I need a special crimp tool for Sta-Kon non-insulated terminals?
Non-insulated barrels crimp with the non-insulated (open die) nest of a terminal crimper, not the color-coded insulated nest. Using the insulated red nest on a bare brass barrel will deform it and give you a loose joint on 22-18 AWG wire.
6) What is the overall length of the A250-TB terminal?
Overall length is .73 inch. Worth checking against the depth you have behind a switch or blower terminal, since adding your own heat-shrink sleeve on this bare terminal will add a little more.
7) Are these brass disconnects made in the USA?
Yes, the A250-TB is manufactured in the United States, which is what matters if you're buying against a Buy American or domestic-preference requirement on a government or institutional job.
