AC Distribution Panels

[rgleason]

OK,
I had a tough location problem figuring out how to fit a modern 120vac EFCI GFCI Main Panel into our small boat. I had the BlueSeas panel picked out, but had difficulty finding a location in the main cabin. As it was, the back of the panel would have been in one of the cockpit lockers. I just found this WP unit. It is expensive, but mounting an enclosed WP panel in the cockpit locker is a much better solution for us. Blue Seas 120vac-30a-ELCI-Main-AC-Panel in Enclosure 3116

- Hot Water Tank heater
Only missing one breaker.

Question: Would there be any reason to change to 120/240 50A? It is a very simple system. What would be the advantage? Would plugging into shore power internationally be any easier?
