Galvanic Isolator – Do I need one?
We are often asked whether it’s worthwhile buying a Galvanic Isolator. Good question!
Generally speaking if :

Your boat has an engine, (either outboard or inboard)

The flow chart gives you a simple way to check.
If you DO need a Galvanic Isolator, there are two categories that they fall into: Plug In, and Wire In.
As the name suggests, a Plug in Galvanic Isolator simply plugs into your mains hook-up cable. It takes a few seconds, and you don’t need any tools or electrical knowledge.
A Wire In Galvanic Isolator is permanently installed on the boat. Fitting is simple and straightforward, and well within the capabilities of a reasonable DIY’er. Full instructions are provided of course.
