I don't have the size handy, but I can tell you that you do not want this as your main refrigerator. It is small and while the refrigerator is self defrosting, the freezer is not. It is a mess to defrost. You have to soak up water with towels in the bottom of the freezer or let the water drip onto towels on the counter, but the counter is going to get wet no matter how you defrost. If you are working with anything wet with your hands above your shoulders, water runs down to soak you unless you are wearing cuffed gloves. The refrigerator has the serpentine evaporator at the top of the compartment so you have to be very careful placing tall bottles inside. In the 50s and early 60s, these coils were famous for freezing bottles of milk that came in contact with them. As a fun refrigerator or bar refrigerator, it works well enough and if you get good door gaskets and have air conditioning that keeps your home's humidity low, you might not have to defrost more than once or twice a year if you are not opening the freezer a lot. The thing that is surprising about it is that it is so shallow front to back. It is the depth of wall cabinets, so that is slightly more than a foot. Since its construction technology also pre-dates foam insulation, both insulation and capacity suffer.
It has a plug on the end of the cord. There is a giant piece of V-shaped angle iron that bolts to the framing of the wall. The refrigerator is lifted onto this and then there are screws that go into the wall from the top of the cabinet in the area covered at the front by the grill. Because of the very small size of the freezer (even the ice cube trays are short) GE offered separate 24 inch wide under counter roll out freezer drawers, but we have never seen one in a place where the wall-mount refrigerator has been installed. They too pre-dated GE's FROST GUARD technology.
