Marina gfi wiring

[Arnoldb]

We are wiring new docks at our marina , a lot of the boat require 2 30 amp 125 volt connections , one will run most boat functions the 2nd one is for boats with air conditioning. I am concerned that with the two GFI single pole breakers will trip each other when connected ?

I have seen that be a problem but you are dependent on the individual boat wiring..about all you can do is provide the receptacle
(Note: For shore power I hope you are using 30ma GFP and not GFCI)

Many boats will use a Y connector to provide 120/240V at 30A on a 50A shore power connection, with limits
on what can be used on the boat.
Having opposite phases in a single pedestal is good for them, and I've done this without GFI tripping.
I'm a marine engineer on traditionally rigged vessels, and have done this a number of times, mostly successfully.
Ive also a seen pedestal that were NOT wired that way- a pain, especially when the breaker that trips is
200 yards away and locked up- New Castle, DE.
I'd appreciate comments from others here.
