    This is a very well done video guide teaching about galvanic corrosion.

    A very late comment, fault current is not sent to ground, fault current like all current is simply trying to get back to the power source. It does this via the safety ground as this is what it is provided to do. The safety ground wire is actually connected to the neutral at the power source. Which in this case will be the nearest shore power transformer. Whether in the marina or up on a power pole nearby.
    This ensures the safe conduct of the fault current to the source. It also provides the means to trip a GFCI on the incoming hot and neutral wires by creating an imbalance of the current measurement between those two same wires. If you bond the shore current safety ground to the battery negative (call it the engine block if you want but this is just a path in the negative path of DC current of the boat.) You then risk putting AC fault current into the water at the marina. This current will try this path if there is also a fault at the shore power connection.
    The only reason to ground the AC safety ground to the boat DC negative is if you have an isolation transformer installed. In which case the boat AC safety ground is not connected to the shore safety ground.

    We’ve not got a boat, it’s the science that’s interesting.

    The 240 volt ac earth is always run back to shore . Normal practice and our recommendation for safe practice is to bond the a.c. earth (ground) to engine block or metal hull to ensure maximum protection onboard. This is usually done by running a 6mm earth bond from the 240 volt a.c. consumer unit earth buss bar to either the engine block (on grp boats) or directly to a clean contact point on the hull in the case of metal hull vessel.

    great demonstration of sacraficial anodes & galvanic corrosion.
    very NOBLE of you to help others! pardon the pun.

    I visited your site. You several different sizes. Which isolator will I need? Thanks you. Steve

    Think the 240v ac circuit earth should be run back to shore. On the diagram it seems to suggest that it is also connected to the to the boats ground circuit. Do you mean the hull or just the 240v appliances?
