Thanks for the help,
I have both 30 amp and 50 amp service, the breakers in the garage/trunk are not tripped and the breakers/power selection at the main panel have 3 options, 120v shore, 240v shore, generator. 

With the breakers in the garage on and all three of the main AC panel breakers off, the 120V shore green available light comes on at the AC Distro panel and the shore power breaker holds. I also get a reading of 120V on the AC volt meter also at the AC Distro panel. As soon as I flip on the 120v Shore breaker at the AC Distro panel, the pedestal breaker trips. I have tried this with all circuits in the off position and still no luck. 
When I connect the 240v 50 amp shore cable and attempt to flip on the breaker at the pedestal it trips immediately. I have tried with the breakers in the garage off as well as everything off at the main distribution panel. 

I have noticed the meter selector switch(rotary style) no longer stops but will click through all the way around 360. This switch is called a meter selector switch by Tiara and is a 3-pole/4-position switch. The options are 120v/240v/generator/inverter. It seems to work but I fear it might be faulty and giving me false hope.

Any suggestions on what to look for so I can get shore power stable is greatly appreciated!
