You could check for a short in the wiring in the outside unit. Other than that it could be compressor time and that should be left to a pro.

Yeah sounds like the compressor tripping the breaker. Take a amp reading from the compressor to see what kind of amp draw you get. The nameplate should give you the start amps and run amps on the comp.
