My daughter just bought a house that has a window set up to take a large
window ac unit, with a 220 plug installed below it. (that is the only
electric plug near the window) She wants to put a smaller ac unit in that
window, that has a normal 110V plug. What is the easiest (safe) way of
converting that 220 plug to a 110 one?
Is there such a thing as a converter plug that would plug into the 220
receptacle with a 110 plug on the reverse side?
Thanks

You must look and see if there is a neutral (white) wire in the box. (4
wires- black, red, white, bare)
If there is then you can replace the 240V outlet with a 120 V outlet.
Connect the white, black, and bare ground wire to the outlet. Cap off the
red wire in the box. (Or the red and black hots could be used on a 'split'
duplex outlet where top outlet for the AC and the bottom outlet for
something else).
If there is no neutral (white) wire then there is no 'legal' way to do this
without running a new cable.
