A:Answer Hi Riley.
Thank you for reaching out regarding your Samsung - 4.0 Cu. Ft. Stackable Ventless Heat Pump Electric Dryer if the dryer work with a 3 prong 250V 30 a plug and if you need to purchase the wire separately. Regarding your concern, most U.S. dryers require a 240 volt, 60 Hz AC-approved electrical service. Some require 208 volts, 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.
• If a power cord is used, the cord should be plugged into a 30-ampere receptacle.
• The power cord is not provided with U.S. electric model dryers. This cord is sold separately.
