I believe you have the wrong plug as you do not have a ground..
You want a 50 amp twist lock plug. It has 4 connections for USA boats. For European boats you use only 3 of the 4 connections.
The green/yellow from the boat goes to the green in the plug.
The blue from the boat goes to the black in the plug .
The brown from the boat goes to the red in the plug. .
The white neutral, is not used.
The neutral wire is used on USA boats to get 110 volts between the black or the red.-this is not used.

sv Viva #374 is wired for Europe 240V with 3 prongs; Phase (hot), Neutral, Ground
Ala Wai Marina in Hawaii does have 240V with 3 prongs, 2 Phases (hot) and Neutral. No ground, plug protected by a breaker at the Marina socket..
110V is coming between one phase and neutral. Then 240V is coming from the 2 phases.
I bought a socket NEMA L6-30P wich is fitting the Marina socket.
My questions are:
1-How do I wire this NEMA L6-30P socket to replace the European Socket?
I foresee 2 mutually exclusive options:
11- wire one US phase in the European Neutral
12-combine the 2 US phases in the European Phase
Both options seems wrong ...
2-Do I have to install a 30A "galvanic isolator" - as I have seen in previous threads - if the Marina socket is protected by a breaker?
Any advice and tip will be greatly appreciated.
