Sorry, but that's not correct. At 240V, it will draw half the current that it
did at 120V. This will provide a much faster start, even if the 120V circuit
was properly sized.

Woah up a second here!

That's true if the device is built to run off of 240 Volts.

But if the internal resistance is the same as it was in the 120
device, it will draw TWICE the amperage - until it "opens".
