This is our MOST EXPENSIVE Galvanic Isolator… And there’s a GOOD reason Why!
Galvanic isolators do a great job of protecting your boat from Galvanic currents that could otherwise cause serious, (and expensive) damage. But how do you know it’s working?
Well… you’ll certainly see when your boat is next out of the water, but in the meantime, our Self Test galvanic isolator has the answer. Two built in LED’s constantly monitor for earth leakage problems, and a simple “Test Button” lets you check your isolator and boats earthing to ensure that it’s doing its job for you.
Just like our other plug-in galvanic isolators, installation is simple: just plug it into your shoreline hook-up lead, at whichever end is most convenient. No wiring, no maintenance — just quiet, continuous protection and the reassurance that you can check it’s working it whenever you wish – you don’t even need to disconnect it.
