What is a galvanic isolator and what does it do?
The Mercury Precision Galvanic Isolator is a solid-state device that is series connected in line into the boat’s green safety grounding lead ahead of all grounding connections on the boat. This device functions as a filter, blocking the flow of destructive low voltage galvanic (DC) currents, but still maintaining the integrity of the safety grounding circuit. A galvanic isolator is only necessary on boats utilizing a shore power connection.
