I have seen this type of problem when the temperature starts to climb. There is usually a "delay" on AC run times so if the AC has been running to get your house to 73 and then shuts off, it has to wait (normally 5-8 minutes) before it will restart. If you have a programmable thermostat, the thermostat might be causing a conflict with the built in delay on the AC unit and the delay that is built into the thermostat. The AC unit then tries to fire up to early and due to extremely high pressure in the compressor, the motor blows the circuit breaker trying to spin it. In some cases your HVAC professional can install what is known as a hard start kit to reduce the time that is required to lower the compressor pressure.

Good Luck.
