2003 342 fiesta vee A/c trips breaker

Our a/c will occassionally totally turn its self off and sometimes come back on and other times totally trip the breaker.  If it doesn't come back on or trip break we can switch from shore power to genny power then back to shore and turn the air back on and it works fine.  Lately, if we try that both the house and ac breakers trip.  We think we need to replace the shore power ac curcuit breaker.  Does anyone have an electrical manual or know what that breaker is?

Just saying, if the plug in on the boat was 'fried'; replace your shore power cords too!!!!!

I have similar issues and was told that I needed to replace the ac controller, picture below.  I figured out that if I leave the thermostat in the middle, just like it is on the picture, it works fine.

WE figured it out - the plug in (outlet) on outside of boat for AC and house plugs - house was fried and AC was very loose - replacing both.  Thanks
