Thanks, Dave,
So, should it reduce galvanic corrosion, or are there other benefits?

It isolates the shore power ground from your boat by making that connection with transformer coils as opposed to a direct wired connection. Iso transformers used to be large, heavy, and expensive but the modern ones are smaller, lighter, and somewhat economical. I think they're a good idea for boats that spend time in marinas. Previous owner of our boat installed one and I'm happy it's in there.

Sorry to be the dummy again, but what purpose is served by the isolation transformer? What's it isolating and from what?

Hi Andrew and Kate

On our SM, the previous owner added a Charles isolation transformer and it is placed in the lazarette on the shelf next to the propane locker. We have an A/B switch in the engine room to select between it and and the standard shore power plug.

This has work well for us.

I wish to install an isolation transformer on my SM2K - does anyone know if there is a recommended location for this. I was thinking of making a bracket for the rear engine compartment bulkhead. But not sure if there are any issues with this - the transformer ways about 25kgs.

thanks in Advance
