There is a voltage drop from the panel to the final load (say motor). Generally, the full load ampere is determined by using the rated voltage. If the full load ampere is determined by using the voltage at the terminals (Voltage at the panel minus the voltage drop in the cables), then the FLA would be bit higher than the FLA at rated voltage at the terminals.

Which current to be used in the Voltage drop equation to determine the voltage drop?
