Hi Tina,
Thank you for reaching out and we hope you are in good health. We appreciate your interest in Samsung home appliances, specifically with Samsung - 7.2 Cu. Ft. Electric Dryer with 8 Cycles - White.
Most U.S. dryers require a 120 / 240 volt, 60 Hz AC approved electrical service. Some require 120 / 208 volt, 60 Hz approved electrical service. The electric service requirements can be found on the data label located behind the door. A 30-ampere fuse or circuit breaker on both sides of the line is required.
I have shared the user manual link below. Please access the link and turn to page 13 for the electrical requirements.
