PI: Have you been able to do a polarility and voltage check. Your AC not working properly may be do to a low voltage condition. What is the recepticle voltage with nothing connected to it versus when the AC unit is connected? The 20 amp line that runs to my 8000 btu window AC drops about 1.5 volts in high speed (and about 3 volts with a 1500 watt space heater running). If you are getting higher voltage drops it may mean that the voltage is dropping because of some sort of dangerous problem with the installation.
Problem areas:
Clamping a connection on insulation instead of bare wire.
Wire insulation compromised so wires are touching.
Wrong breaker used for your panel box. Each box will accept only certain breakers.
Manufacturing problem with the installed breaker.
Manufacturing problem with the installed recepticle (AC plug may be warm/hot to touch).
Numerous others but the above seem most likely.
Veridan: Were you planning on using an existing orifice or creating a new one? Either way is equally lethal!
