Our isolation transformers also reduce possible galvanic corrosion of hulls, propellers, or other metal parts under a ship, eliminating the need for installing galvanic isolators, sacrificial anodes and polarity alarms. By preventing DC currents traveling between a shore ground connection and metal parts of a ship, no current flow path between two dissimilar metals (electrically in contact and simultaneously exposed to an electrically conductive liquid) can occur, and corrosion is thus prevented.
It is important, therefore, that the Ground conductor from the Shore connection is NOT CONNECTED to the Power Inlet housing nor the Isolation Transformer enclosure PE (except temporarily when in dry-dock). On the floating AC output of the Isotransformer, it is possible to jumper a Neutral-Ground bond for allowing GCFI/RCD breakers onboard.
Warning: Never disconnect the shore Ground (PE) conductor unless you use an Isotransformer. Because GCFI/ RCD will not trip, nor a fuse will blow in the case of a short circuit current to metal parts on a vehicle, always use an Isotransformer with Neutral-Ground bond on the secondary.
