Try running the unit by 1st turning the temp up to 90 -- then turn on the high cool. After the fan runs for about 30 sec slide the temp slowly down to 70 deg. It it still trips try the same method when using the Gen. This process will help determine if it is a bad blower motor causing the amp spike or if it is the compressor. Or possibly low shore voltage causing the Tripped breaker.
