Hi Chris,
In my mind, everything at 12VDC or 120VAC is part of the boat and should be treated like on any other boat. Everything at drive voltage, 48VDC in my boat, should be isolated. So if you have a DC generator, the output needs to be isolated. If it has a 12V starter, that circuit is part of the house circuit.
This does raise the question about isolation within a single component. Is the DC side of your shore charger isolated from the AC side? How about your inverter? The only items in question are the ones that bridge the gap between both sides. Personally, I don't know the answer for my charger, but it is only wired into the drive system, the AC side is still a cord with a standard plug and I use an extension cord to connect to shore power. I don't have an AC system on my boat, so my systems are pretty simple.
Fair winds,
Eric
