Bocatech's Failsafe Galvanic Isolators meet ABYC A-28 standards for continuous safety in the event of compromised grounding on board a ship while connected to AC Shore Power. They also provide excellent galvanic corrosion protection against costly metal loss.
Sacrificial zincs corrode away as they protect metal through 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 Bocatech's Failsafe Galvanic Isolator between the AC safety ground and DC bonding system blocks a majority of the low voltage currents. In addition, corrosive action on the zincs is significantly reduced, while the integrity of the critical safety ground path is maintained. This results in 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.
