Anode on a wire ?

[Andy Bav]

I can access your link now FF, it looks like the e.bay version needs to be wired in, whereas the one I was trying to link to (not very well) basically plugs in between the pontoon supply and your powerlead hence (possibly) the price differential ?

No, indeed I was referring to the company safeshoremarine rather that the unit, I would prefer to have one just plumbed in rather than the remote one as our shorepower inlet is on the transom and its not the usual uk waterproof unit, its the expensive italian one beginning with an M which I can't remember the name so the plug n play one would need re-wiring anyway..

You just mount it next to the consumer unit in the boat and wire it into the earth between the consumer unit and the shore power inlet. If the get the remote unit, it needs to be tested regularly to see it is operating correctly so you may just as well test the GI itself with a multimeter at regular intervals.

Many multimeters are not going to be able to do much testing on a GI - the test voltage on resistance settings is usually very low. You'll certainly need a "diode test" setting on the meter and I'm not sure that even that can be relied upon - GIs tend to connect two or more diodes in series to bring the barrier voltage up.

Clearly you need to use a multimeter that is capable of performing the test - that is one with a diode test facility. The manufacturers of that particular GI seem to think such a test is satisfactory as they recommend it.
