Cost effective solution for eliminating galvanic currents up to 1.1V and reducing electrolysis. Suitable for 120V and 230V installations, features a built in display for monitoring and testing. 

Despite having a well-designed and bonded system and correctly installed sacrificial anodes, when we connect to shore power we are creating a circuit between our own boat, the dock and other boats in the marina through the A.C. power earthing wire, an essential safety component of an A.C installation. This circuit can produce galvanic currents between dissimilar metals on board and between neighbouring boats and the mooring and can lead to corrosion damage.  Correctly installed the galvanic isolator will block galvanic currents in the shore earth connection up to 1.1V. Above this level current is allowed to pass maintaining the safety earth connection in event of a malfunction.

For almost every combination of metals likely to be found at a mooring the 1.1V maximum is sufficient to block corroding currents. With the built-in indicator we can quickly check the status of the system and in the event of a high current disconnect the shore power to prevent corrosion.

D.C. galvanic current can also be caused by other shore earth connections such as telephone & cable TV.
