50A Galvanic Isolator (GI-50) by Newmar®. The Galvanic Isolator (GI) is a device for reducing stray low voltage currents traveling between the shore power's AC safety ground (earth) and the boat's DC bonding system, while maintaining the safety requirement of an electrical path to ground in the event of a short circuit.

These stray currents are a chief cause of destructive galvanic corrosion (sometimes referred to as "electrolysis") which eats away at sacrifi cial zincs, or if there are none, destroys outdrives, propellers and through-hull fittings.
