Both 220 and 240 volts are used to power dryers, depending on the electrical system in the region or country where the dryer is used. The terminology varies, and sometimes the terms "220 volts" and "240 volts" are used interchangeably, as they are relatively close in voltage.
In the past, many countries used a 220-volt electrical system. However, over time, some regions transitioned to a 240-volt system. Despite this shift, appliances like dryers are often designed to work with both voltage levels to accommodate various global markets.
To add to the complexity, some countries have multiple voltage standards, and the voltage can vary in different parts of the same country. For example, in the United States and Canada, both 240-volt and 120-volt electrical systems exist. The standard voltage for household outlets in the US and Canada is 120 volts, while the standard voltage for larger appliances, including many dryers, is 240 volts.
If you are purchasing a dryer or any other high-power appliance, it's crucial to check the voltage and electrical requirements specified in the product's user manual or on the manufacturer's label. This information will ensure that the appliance is compatible with the electrical system in your area and that you have the appropriate outlet and wiring for the appliance. If you are unsure or have any concerns about electrical compatibility, it is best to consult a licensed electrician to ensure a safe and proper installation.
