galvanic isolator with lifetime warranty

LIFETIME Guarantee


Fitting a Plug In Galvanic Isolator couldn’t be simpler. You don’t need any electrical knowledge or tools, and fitting takes about 30 seconds. And it’s guaranteed to work just as well as the wire-in type. 
galvanic isolator with earth leakage warningThis model offers many benefits over standard galvanic isolators.

The most obvious benefit is the Status Alert Indicator, which constantly monitors your boats earth connection for faults that could lead to corrosion of the hull, or even life threatening mains voltage earth leakage faults.

Bright, easy to read indicators warn you immediately a problem is detected.


Under the bonnet, there is our “2-stage Protection System”, which protects your hull against electrical noise and Galvanic & Stray Voltages up to twice as high as a normal galvanic isolator.


image showing how electrical noise can adversely affect the operation of galvanic isolators2-Stage Protection is advised where you have electrical items with Switch Mode power supplies.

Most battery chargers, mobile phones, computers, TV’s etc have these, and some of them can introduce electrical “Noise” into your boats electrical system. In extreme cases, the noise can defeat single stage galvanic isolators, so we have developed our 2-Stage Protection System to give you added protection.

How It Works…

Check your earthing at a glance.

how to use a galvanic isolatorBoth Lights OFF: Your galvanic isolator is operating normally. No action required, so just check back occasionally to ensure that all’s well.

One Light ON: If either of the lights are on, it indicates DC leakage. This can cause severe corrosion to your boat. Our instructions give clear basic advice on how to resolve the problem.

BOTH lights ON: If both lights are ON, this indicates AC leakage, usually from the mains wiring or a connected appliance. AC leakage can be a danger to life. Please see instructions for help in rectifying the problem.
