eeeee:
If a 240 motor is connected across 480 we know for certain that the magnitizing current will be very high. Run the experiment I previously described with an unloaded transformer and you will see the rapid rise in current as voltage increases. This produces lots of heat. That is why excessive input above rating on a continuous basis burns up these devices.
