This has a cord that is sold separately and is plugged into a 220 0utlet. A licensed electrician can advise you of the best way to wire your home for a new dryer.
I have had an LG washer and dryer in the home that I am selling for the last 8 years and they have performed fantastically. I have bought these new LG Washer and Dryer for my new home and I am sure that they will work as well as my old washer and dryer.
