ASAE/ASABE EP329.3 (R2022)

This Engineering Practice concerns 3.7 kW (5 hp) and larger single-phase motors, and three-phase motors with phase converters, that are started infrequently (generally with less than 6 starts in a 24-hour period and not more than 1 start between 6 p.m. and midnight) and that serve loads with non-pulsating power requirements. Some examples are motors for fans on crop dryers, feed grinders, silo unloaders, irrigation pumps, and auger feeders.
