Magnet wire help

  1. Feb 3, 2009 #1
    I have ordered a spool of wire with these properties:

    NEMA-MW-80 155C This magnet wire has a copper core with a dual film of polyurethane (85-90 percent) with polyamide(nylon) as an outer coating making up the other 10-15 percent.

    .0169 inch diameter

    rated to 155 degrees centigrade

    What is the resistivity of such a copper wire, because i know that R=l*p/A.

    Using this equation(or others) is it possible to calculate the maximum current that would keep the wire under 155 degrees?
