Shore Power Isolation Transformer

Connecting a boat to shore power is a minefield of dangers and difficulties. When properly installed, Charles Marine Isolation transformers will electrically isolate the AC shore power from the boat's AC power system. The boat's electrical system and the grounding conductor are not actually connected to the shore-side power. There is no direct electrical connection between earth-grounded shore AC power and the onboard electrical system. The shore ground is connected to a shield that is wound between the primary (shore) and the secondary (boat) transformer winding. The connection of this grounding wire only to the shield of the transformer isolates the boat's AC electrical system from shore.
This multi-voltage model can be set to convert AC voltage from 110 volt to 220 volt and allows a European boat to safely connect to US style shorepower outlets. Removes the need for the dangerous and illegal method often used, where neutral and live on a European boat are connected across the two live poles of a US 110/220 volt 50 amp socket.
Also allows a US wired vessel to connect to single phase 230 volt European outlets.

Increases safety.
Greatly reduces shock hazard especially for swimmers.
Eliminates reverse polarity faults.
Isolates boat from corrosion producing stray currents.
Isolation only 1:1 voltage, isolation plus 110 v to 220 v conversion or isolation plus 220 v to 110 v conversion.

Meets ABYC and NMMA standards and is CE certified.
