Know what you are buying. This is for a 20 amp socket (the description above says "input: 20 amp") that you can find in a special fridge or freezer so that one pin is perpendicular to the other and won't fit. a 15 amp parallel-pin outlet that would be a conventional outlet in US homes. Give them a star if you don't have a clear picture of the plug when you need it, but note that the 20 amp, 30 amp, and 50 amp outlets have differently shaped plugs, so you don't have a plug with too thin ones Plug in wires and hopefully you can prevent yourself from burning buildings and possibly the people inside.
