galvanic isolator

[shadowdancer]

I have two 30 amp shore power connections. do I need an isolator with each or can I combine the two greens and use 1 isolator.

A single isolator will be fine, but it has to be rated for the combined fault current.

At least as far as electricity is concerned. I don't know if there are regulatory rules that would forbid it.

If you had a 60a galvanic isolator you could combine. Likly you will find 30 and 50s.

The 2 grounds are joined at the dock and on the boat anyways.

Yes a single will do but must be rated and set up for such. Mine has double studs and is 60 amp
