Galvanic Isolators
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 (see diagram), 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, all units feature a large capacitor, providing a
secondary low impedance path for sending AC current to ground.
Two models are offered; rated for 30 or 50 amp shore-power.
