Hypertech
Item #: GIY12105 -
The Hypertech Galvanic Isolator blocks DC electrolysis currents from flowing in the ground conductor of your shore power hookup. It provides approximately 1.2 volts of isolation to isolate electrolytic voltages from the dock but yet pass safety currents to ground in the event of a short circuit, or power leakage on your boat. Hypertech Galvanic Isolator Features: Fail Safe 50 amps AC continuous rating. Use on any shore power connection up to 50 amps. Only one required for dual 30 amp...

Victron Energy
Item #: GIV13020 -
The Victron Energy Galvanic Isolator prevents electrolytic corrosion. It blocks low voltage DC currents that enter your boat via the shore power earth wire. These currents can cause corrosion to the boat’s underwater metals, like the hull, propeller, shaft and so on.
The galvanic isolator consists internally of two diodes which are connected in anti-parallel fashion. When they are connected in this way, the diodes allow current in both directions but only above a certain threshold voltage. The...
