Newmar Gi-50 Galvanic Isolator

Galvanic Isolator

Sacrificial zincs corrode away as they protect metal thru hulls, shafts and props from damaging electrolysis. Stray, low voltage current flowing between the AC safety ground and DC bonding system is a principal cause of this "galvanic" action.

Installing the Galvanic Isolator between the AC safety ground and DC bonding system, blocks a majority of the low voltage currents and corrosive action on the zincs is significantly reduced (while the integrity of the critical safety ground path is maintained.) This means a significant savings in boat haul-out fees and zinc replacement costs.

For additional safety, both units feature a large capacitor, providing a secondary low impedance path for sending AC current to ground.

Newmar Gi-50 Galvanic Isolator October 28, 2014
Reviewer: Wilson Echols from Gainesville, GA  
After adding the second isolator, I find that the small amount of stray current was gone.
