what gives a treadmill more power amp volts?
The amperage rating on the DC motor is not the amperage the treadmill will be using from your wall outlet. Most treadmills only need 10-12 amps from the wall (or less), so a 15 amp circuit is fine, regardless of the rating on the motor. Just look at the amperage rating on the treadmill to see what your wall outlet needs to supply. #2 see #1. #3 Current is always lost in the form of heat when used to power a device. Be it in the motor, the electronics or even the line supplying the current.
