Basically the answer to all you questions is no. I'm no cook (I can boil water) but I thought you cooked something at a certain temperature for a certain length of time. Without going into a long tirade about voltage, amperage and resistance, I'm sure a oven that size would be capable of generating enough heat to reach what ever temperature you need with 120 volts. No it will not be any cheaper to operate at 240 volts. However, it would probably require you to rewire for 240 volts.
Big-D could not be more wrong. Watts is the measure of power. Fifteen hundred watts is 1500 watts. Fifteen hundred watts at 120 volts (and it is 120 not 110) is 12.5 amps. Fifteen hundred watts at 240 volts is 6.25 amps. That is 12.5 amps on one leg for 120V and 6.25 amps on two legs for 240V. Watts is what you pay. |
