This means that it requires a disconnecting means for each motor, and it must be located in sight from the motor location and the driven machinery location.

Multiply the FLC of the largest motor by 125%.

Add up the FLCs of the other motors.

Multiply the continuous non-motor loads by 125%.

Add up all of the above to the total of the non-continuous loads.
