Best Answer

The voltage has nothing to do with the gauge of wire needed to supply a given circuit. The size wire is determined by the amperage of the overcurrent protection device (circuit breaker, etc.) being used to supply power to the circuit.

The gauge of cable depends on the amount of current to be carried, and it could also depend on its length if it is more than about 100 ft.

yes 240volts is 240 volts

You would have to run new wires to obtain 240 volts or use a step-up transformer.

120 volts and 240 volts. Typically 240 volts is supplied to the house electrical service entrance. It is split into it's 120 volt components via two buss bars. Hooking a circuit up to just one bar yields 120 volts. Hooking into both gives 240 volts.

You don't.

There's something wrong here. 3250 watts on 240 volts is only 13.5 amps, not 40. And that would be 12 gauge wire on a 20 amp circuit. But that seems low for an oven. If it truly is a 40 amp appliance then the gauge would be #8 wire. The wiring info that comes with the appliance should tell you everything you need to know.

No, unless the motor was wound for dual voltage operation, which it will state on the motor nameplate, a 110 volt motor run on 240 volts will be damaged.

Voltage does not affect the cost to run. You pay for the wattage, the higher the wattage the more it will cost to run.

Yes, if the motor is rated 240 volts 3 phase.There is such a thing as 240 volt 3 phase power.However if you are asking if you can use 240 volts single phase on a three phase motor, then the answer is no.

208 to 240 volts depending on your local power supply.
