When a motor starts, it briefly draws considerably more amps than when it is running. This is the reason people run higher HP motors on 220, as the required amps is cut in half. When you start your table saw, you hear it change in pitch briefly. That first sound is when it basically wants more amps than is available. If you have enough amps, you start right up with that steady sound. The easiest way to get more amps is to double the voltage.
