This is a large Panasonic microwave that is made to be built in. However, it can be used like a regular one. It has a normal plug and works just fine. The only downside is the top isn't finished and it's dirty. I plugged it in today and heated water no problem. Exterior is 30" wide, 15" deep and 16-1/2" tall. Interior is 21" wide, 13" deep and 9-1/2" tall. A great microwave for the basement, lunchroom or job site...for free!
