Post Subject: Galvanic isolator

Our boat is moored between 2 live a boards, one of which is a wide beam. We do not normally have power on although we are connected to the shore line. Should we fit a galvanic isolator?

All the time the shoreline is plugged in your boat hull SHOULD, if the wiring is correct, be connected to the shore-side earth line (green & yellow). This connects your boat to all the others with shorelines plugged in and this increases the potential for electrical corrosion to take place between your boat, other boats, the ground, or any metal pontoons. If the shoreline is not plugged in and any metal pontoon/walkways are buffered from the hull by rubber fenders then the boat should be isolated from everything else so no corrosion can take place. The overall safety and effectiveness of galvanic isolators and isolation transformers are hotly debated and some strict readings of the IEE regulations might imply a GI is not allowed. To try to simplify things I say that if the boat is to be left for long periods on shore power then an isolation transformer probably has the marginal edge. Otherwise a GI WITH INBUILT INDICATION OF WHAT IT IS DOING should be perfectly adequate. TB
