The website you linked to does indeed make the claim that you can save money by wiring a pool pump to 220 volts instead of 120 volts. However, this claim is false. In fact, you will actually use more electricity by wiring your pump to 220 volts.The reason for this is that a 220-volt pump draws more current than a 120-volt pump. This means that the pump will use more electricity, even if it is running for the same amount of time.In addition, a 220-volt pump will require a larger wire size than a 120-volt pump. This can add to the cost of installation.Overall, there is no advantage to wiring a pool pump to 220 volts. In fact, you will actually use more electricity and spend more money on installation by doing so.Here is a more detailed explanation of the electrical principles involved: Voltage is the electrical potential difference between two points. It is measured in volts. Current is the flow of electrical charge. It is measured in amps. Wattage is the rate at which electrical energy is used. It is measured in watts.The power consumption of a pool pump is determined by its wattage. The wattage of a pump is determined by the following formula:

Wattage = Voltage  Current

As you can see from this formula, the wattage of a pump will increase if the voltage or current increases.In the case of a pool pump, the voltage is fixed by the power supply. However, the current can vary depending on the load on the pump.When a pump is running at full load, it will draw more current than when it is running at no load. This is because the pump has to work harder to move the water.A 220-volt pump will draw more current than a 120-volt pump, even if they are both running at the same load. This is because the voltage is higher in a 220-volt pump.As a result, a 220-volt pump will use more electricity than a 120-volt pump, even if they are running for the same amount of time.
