Newmar Gi-30 Galvanic Isolator Shorepower - 50A 250V RF remote/wired remote readyGalvanic 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
