comment Why won't my AC system turn off after I flipped the breaker?
Side Note: on Trane AC units the "B" wire is actually the "C" wire and the "O" wire is the "B" wire (well, sometimes).

comment Why won't my AC system turn off after I flipped the breaker?
After turning off all of the breakers in the breaker panel to no avail (I still wonder what the 2 breakers labeled "Air Conditioner" do). I found a black box connected to the unit with a door on it. Opening the door revealed a handle with the label "Miscellaneous Switch." I gave it some thought as to what it could be; determined that it isn't going to launch any nuclear weapons; then yanked on it. Voilà! My energy-saving programmable thermostat is installed and working great. Thanks.
