How to Convert KVA to Amperes for Single and Three Phase Circuits Using Tables

The following tables list the current in amperes for different KVA values for both single and three phase circuits for 120, 240, 480 and 600V circuits. To get the corresponding value of AMPS for a given KVA, simply read off the current value at the required voltage for the given KVA rating.
