How Motor Full Load Amperes Fit Into the Application
Full load amperes are an important reference point when evaluating a motor and the equipment used to control and protect it. Motor current can affect the selection and application of variable frequency drives, soft starters, contactors, overload protection, conductors, disconnects, and other electrical components.
The values in these tables are useful for general reference, but the motor nameplate should be used whenever it is available. Actual equipment selection also depends on factors such as motor type, voltage, service conditions, application requirements, starting characteristics, and applicable electrical codes.
