Why do people have 240/230/220V dryer plugs on the outside of their houses?
There are more than a handful of 220V appliances which can use 220V (240V) single phase receptacles. Arc welders, portable range tops, BBQ's, smokers, pumps, compressors, portable AC's/heaters, ceramic kilns, etc. Most permanent installations are hard wired, but there many different types of 220V convenience receptacles. (that's the problem in this thread) Many European countries use 220V single phase as the standard household voltage indoors as well as outdoors.
Using (plugging into) a plug that looks "close enough" should be a good enough warning sign, but, it often isn't.
