But it can also lead to galvanic corrosion and other problems. Good engineering practice, Lloyds rules and the Recreational Craft Directive all call for an on-board AC earth system to be bonded through to the sea. On a metal-hulled boat this is done by taking the earth to the hull, on other craft it is via a specific ‘grounding’ plate. In making this important safety connection you create a galvanic loop which can accelerate corrosion of the boat.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eThe symptoms\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eOn metal-hulled boats galvanic corrosion can cause general hull corrosion as well as localised pitting - especially along the waterline. Sometimes this pitting and corrosion is localised - perhaps close to shore based metal objects. This corrosion of the hull happens despite the fitting of anodes. The ships’ anodes also tend to corrode at an accelerated rate. On non-metallic hulls anodes corrode at an accelerated rate and underwater metal fittings can experience corrosion despite the fitting of anodes.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eThe Solution \u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eA hull isolation transformer breaks the earth wire on the incoming shorepower. The primary (input) side of the transformer induces a voltage on the secondary (output) side. This is done with no physical connection between the shore cable and the on-board wiring - they are completely isolated from each other.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe output side can then be configured to suit the electrical system on the vessel. For UK built boats this usually means that the output neutral is bonded to earth. This allows the use of single pole circuit breakers and switches.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe boat gets its earth protection from the sea via the hull or groundplate, but no circuit is formed, as the shorepower earth is not connected.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eCustom Transformers \u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eIf your needs aren’t covered here don’t worry.
