Galvanic Isolators

A Galvanic Isolator is simply a marine device consisting of a blocking diode assembly connected in series in the green grounding conductor of your shore power wiring, between your shore power inlet, on board and the main panel grounding bus. This marine electrical component is designed to block movement of low - level DC current on & off the boat, which is typically associated with galvanic corrosion. If you boat stays in its slip at the marina, the majority of the time, then it’s suggested you install a Galvanic Isolator.
