Converting Ampere between Single Phase and 3 Phase

Converting amperage between single phase (120, 240 and 480 Voltage) and three phase (240 and 480 Voltage)

Sponsored Links

Sometimes it is necessary to turn between power (VA), voltage (V) and amperage (A). The diagram and table below can be used to convert amperage between single phase and three phase equipment and vice versa.
