Lost my A/C Power

I just bought my used sailboat in March and I am relatively new to sailing.

Anyway,
Yesterday I went to turn on may air conditioning unit and it wouldn't come on. I also noticed none of my A/C power was working (i.e. the light on the A/C panel wouldn't come on) I rechecked all the shore power connections and everyhting was fine. The breaker in the cockpit next to the A/C plug in was fine. I did notice that the beaker inside the cabin did not trip but it is now much harder to flip back and forth.

Does this sound like the breaker blew?
I'd like some input before I start tearing the boat apart.
But the way, everything was working perfectly with the A/C prior to yesterday. And the reverse polarity light did not come on.

Any suggestions?

Thanks

wildcard is an unknown quantity at this point
With the power disconnected, check the breaker for resistance with a multimeter.

I know a good marine electrician who's helped me with AC issues. I routinely work on my DC circuits - but usually leave AC work to qualified pros. Don't mess around with your high voltage circuits unless you know what you're doing.

Also check your shore power cable. Did the female end accidentally fall into the water while it was plugged into the dock?

It is a good idea to check ALL breaker switches, before calling an electrician . . . < G >

Is it easy to replace breaker switches on a sailboat or should I get a pro?

Can I insert a multimeter into a socket to see if I'm getting any amps?

Did you pay your electric bill?, jk, but maybe there is some issue on the marinas end of things, because it sure sounds like you're not getting any juice from the dock.
