Current capacity of wire

Does anyone have a link or just know the current capacity of 26, 28, and 30
gauge wire. Every link I found only mentions the standard Electrical wire
16ga through 750000 but not the stuff we use in our Stamp products.

Thanks in advance for your help

    The current capacity is a function of the size of the wire and the
    insulation properties at a given temperature. But, saying that, according
    to Alpha Wire Company, 30AWG is good for 2 to 4 amperes (depending on
    insulation), 28AWG is 3 to 6 amperes, and 26 AWG is 4 to 7 amperes. One
    must also consider the resistive drop in a given length of wire so that the
    voltage you apply to one end will not be attenuated excessively at the
    other.

    Hope this helps.

    The ARRLHandbook or any good Radio Handbook or Electrical Engineering
    handbook contains wire tables that tell you all you need to know about wire!

    What a quick response and Thanks!!!! I will keep this in mind while
    designing my projects outputs

    Another thing to think about with wires and current. A wire in free air can
    handle more current than in a bundle or conduit. The Alpha Wire site
    mentioned spells that out also.
