The Hypertech Galvanic Isolator Plus provides about 2.5 volts of isolation in the ground lead of your shore power, for aluminum hulls and other metal boats. It is for owners on 30A or 50A shore power who want to protect against stray dock voltage, because standard isolators lose protection on aluminum.

Hypertech Galvanic Isolator Plus Hookup Diagram

Aluminum hulls have a built-in electric potential of -0.75 to -1.0-Volts, depending on the alloy, temperature, salinity, and movement. Conventional Galvanic Isolators provide about 1 to 2-Volts of isolation, so protection is degraded by up to 80% to negative stray voltages when applied to aluminum hulls.

Questions & Answers

Where is the isolator installed?

Inside the boat, in the ground wire between the shore power connector and the vessel ground, preferably within about 15 inches of the shore power entry.

Do I need two for dual 30-amp cords?

No. Only one is required for dual 30-amp connections. Connect the two ground terminals together before passing through the isolator.

How often should it be tested?

The manual says to test it once per season, and again after a nearby lightning strike or an on-board electrical short.
