Maybe the air handler fan? A trick is to turn unit to fan only, then once it's up to speed turn the thermostat to cool, bringing the compressor on. Most modern units though do this already, but maybe this is an older unit?
I have seen inadequate water
flow through the condenser cause pressures to rise and with the higher pressure of course the compressor draws more amps, then the CB trips.. That manifests itself as a gradual increase in amps though over a minute or so, not high amp right off.
