Womack Data Sheet 78: Wire Size and Fuse Ratings for 3-Phase Induction Motors. Download Data Sheet . Current values in this chart are approximate, and are compiled from data published by several motor manufacturers. They may be a little high or low for a specific motor. For selection of magnetic starter heater coils, it is better to follow
