2.3.3 Neutral Current Measurement Considerations

It is possible, in certain Wye configurations to measure the current in the neutral conductor via a shunt resistor,
therefore replacing the third phase current measurement. This function is enabled by setting jumper J15 to
position 2-3. The MAX78630+PPM EV board then connects the shunt voltage to input AIC of the MAX78630.
IC (J41) is not measured in this case.
