There are also outlets used for room air conditioners. I have a 120V
15/20A outlet by one window downstairs and a 240V 20A (IIRC) outlet
for the thru-the-wall AC. Stoves and clothes dryers may also have
either a three pin ungrounded or four pin grounded outlet.

I've heard of those, I don't recall ever actually seeing a 240V window AC
unit though. AC in general is very rare around here and if people have it,
it's normally central. Perhaps 0.1% of the houses have vertical casement
windows that an AC unit will fit in, I suppose that would explain it.

I have (vertical) "casement" windows that are difficult to find
window units for (even uglier to install). I also have two "window"
units installed through the wall. One is a 25KBTU unit on a 240V 20A
circuit, IIRC. The other is 7.5KBTU on a normal 120V 20A (15A outlet)
circuit.

We normally only have two weeks of weather where an AC us useful
(mine have run a total of 20 hours so far this year) so central AC is
a bit expensive.
