Galvanic Isolator Question

[sail sfbay]

New to me 1984 Symbol 44 has two (2) 30 and one (1) 50 amp shore connections. I am guessing the boat will need one galvanic isolator for each shore connection. Is that correct?

I have two 30 amp connections into my boat. My mechanic will be installing two isolators. Electrolysis destroyed my generator's heat exchange and I fear its emanating from my boat. Last time I messed around with anything electronic I almost toasted myself!

Yes, that is correct.

Sorry to be late to be late to the party. Yardina makes an isolator that will connect to the two 30-amp circuits. Not sure about 2 30s and a 50.

Thanks for everyone's inpit. I purchased one 60 amp ProMariner isolation transformer and my marine electrician installed it downstream of the 50 amp/30amp switch and upstream of the electrical panel per the vendor instructions. It is on the common line from the 50 amp and 30 amp shore power supply.

Un isolateur galvanique se pose juste après l'entrée de l'alimentation AC sur la ligne de terre... donc bien avant le chargeur batteries ou autres équipements.
