Isolation Transformer

[MarcZ]

The whole problem with galvanic action is the green wire from the shore power cord being connected to your engine. A power isolation transformer on the power lines doesn't do much good. Any transformer that is loaded or working will give off heat. Charlie

OK I'll bite  ;)   I'm not sure what you are suggesting here  since isolation transformer definitely takes care of "shore power connection to the engine" by eliminating it.

Question about the heat is more of how much rather then if .
We are talking about something like Charles Marine Iso-G2 3.6 kVA - I looked at the manual nothing there, did not call manufacturer yet .
I hope for some real live experience like mark_53 provided. (thank you)

I never had a problem with heat.  The unit is in a steel box so if there is any heat, its inside the box.  As you can see from the picture, I have a plastic set of drawers sitting on top of it.
