Does the pedestal have GFCI breakers? Do you know if they are tripping due to a ground fault or an excessive load? If it is a ground fault I would guess the neutral wires are somehow tied together which can trip ground fault breakers. This is not uncommon wiring in older tiaras. You can look though past posts to get more information.

If the breakers are tripping from over-load it may be time to bring in a professional due to safety. Maybe look to isolate the inverter or isolation transformer if so equipped. If you don’t have one, reach out to Tiara customer service with your hull number and have them send you a wiring diagram. That will help you understand what sits between the inlet breakers and the distribution panel and should show if the neutrals sit on a common bus bar.

The boat was docked and plugged in to the new upgraded power without tripping at the previous owners home berth. While coming home we also had a couple of overnights at marinas with the upgraded electric that is gfi protected. Power worked successfully until the meter switch started failing. Long story to say I’m not convinced it’s a ground fault issue because it was working and nothing was changed on the boat, I’ve only noticed the meter select switch is now able to go 360 instead of stopping when it reaches the inverter and going back to 120v shore 

And yes the pedestal is GFI protected.

I’ve not been able to source a replacement switch and am now researching for replacement options.
Looking for a 4 position 3 pole switch.
