A standard dryer outlet in the United States is typically a 240-volt, 30-amp outlet. It consists of two hot wires (each carrying 120 volts) and a neutral wire. This configuration provides the 240-volt supply required to power most electric dryers.
It's important to note that dryer outlets may vary based on the country or region you are in. If you are outside of the United States, the voltage and plug type may differ, so always check the local electrical standards to ensure proper voltage compatibility.
