I am hoping the power coming from shore side is correct in volts and on the right legs and not crossed over. If not it could trip your breaker.
When you say AC Main you do mean main ships supply AC, not, Air conditioning, right?
Just checking. If the former:
I would disconnect and make sure wiring connections on boat side of breaker are good.
If you don't have a multi-meter or know how to use one you are going to need some one to come in and help.
I would also check the main boat breaker. Keep in off position and see if it ohms out on any leg to each leg and also from any leg to earth bus bar? Once again I would make sure I am disconnected from shore power before doing this.
After these steps it becomes a little more complicated.
If all the other breakers are off, and working properly I believe the problem can only be from shore supply through to breakers.
Because you said it was working at the other dock I would say it is:
1 - Shore supply issue
2 - Breaker Issue
3 - Connection or wire failure
As for docking and fueling. Many, many moons ago my captain told me "When docking go as slow as you want to be going if you were going to hit something"
Also slack tide is always a good time!
I hope this helps.
