Earth Leakage on Boats
Every boat that plugs into an electric hook up should have Galvanic isolation to prevent potentially catastrophic corrosion. Most people know that. But it's even MORE important to know if your boat has earth Leakage problems.
That's because Earth Leakage is much more damaging than Galvanic currents. It's caused by things like chaffed cables or moisture ingress, but more and more, it's from "Tech" equipment like battery chargers, TV's etc. The electronics in these appliances can generate a "Signal" that's picked up by the boat's wiring, and conducted to earth in the form of leakage. This can happen even if the equipment is not actually faulty.
Our Extra Protection models have warning lights that constantly monitor your boat's earthing system, and warn you instantly if you have Earth Leakage. So you can resolve the problem, before it has time to do some REAL damage.
The damage can be severe, like corrosion of the boat's hull and prop'. Also, driveshafts and bearings can be badly affected. And this kind of damage happens FAST. We're not talking about years here - or even months... Pitting can start in days. We've seem props go from brand new to ruined in 3 months.
