The Sumitomo Electric magnet wire technical guide provides comprehensive information on the properties, applications, and specifications of various magnet wires.
Annex C provides a cross reference between NEMA and IEC magnet wire specifications. Annex D provides the formulas for determining dimensional requirements of round film-insulated magnet wire and dielectric breakdown, as well as cross-sectional area and resistance calculations.
Typically a wire tension of 60 - 80% of the maximum recommended tension is used, to ensure that the magnet wire is not elongated and damaged during the winding process. AWG - METRIC - INCH equivalent dimensions
