The voltage requirement for over-the-range microwaves can vary depending on the specific model and manufacturer. However, in many regions, including the United States, the standard residential voltage is 110-120 volts. Therefore, the majority of over-the-range microwaves in the U.S. are designed to operate on 110-120 volts.
On the other hand, in some countries and regions, such as parts of Europe, the standard residential voltage is 220-240 volts. In such cases, over-the-range microwaves are typically designed to operate on 220-240 volts.
To determine the exact voltage requirement of a specific over-the-range microwave, it is recommended to refer to the product's specifications provided by the manufacturer. The specifications will clearly indicate the voltage range the microwave is designed to operate on. Additionally, it is important to ensure that the electrical supply in your home matches the voltage requirement of the microwave to ensure proper and safe operation.
