I believe the outlets people are calling 20a are actually 15a. a 20 A outlet should have one of the legs of the plug have a horizontal notch.... or is that just convention as the above pic shows the breaker as 20a?
You can connect a 5-15 outlet to a 20a breaker but a 5-20 must have 20a breaker. Either outlet will handle 20 amps just fine. And yes the 5-20 plug has the neutral rotated 90 degrees. 5-20 outlet has a T slot on the neutral to accept either.
That pic is an old unit. New stuff requires GFCI for the 15/20 amp outlet.
For those that think a roof air conditioner will not run on 20 amps... better check your branch circuit breaker.
