I'm a student from belgium and I study at the nautical academy (last year now).
My boat is in antwerp and I use it as my student home (or dorm).
I've been reading around about galvanic corrosion trough the grounding cable from the shore power ( 230v 50Hz here).
I would like to stop this possible current flow, but standard galvanic isolators are to expensive for my studentbudget.
Therefore i would like to wire zenerdiodes in between, with a zenervoltage of about 3volts or so.
In this way 2 times (3 zdiodes in serie) in parallel:
The first 3 are installed in the other direction then the last.

What do you guys think?
Will this hold if there is a serious power leak?
