For use with 120/240V 50/60 Hz 16A Supplies

A galvanic isolator will block galvanic currents in the shore earth connection up to 1.1V. Above this level current is allowed to pass maintaining the safety earth connection.

1.1V is sufficient to block corroding currents for almost every combination of metals likely to be found at a mooring. When the voltage at the earth connection is greater than 1.1V, current is allowed to flow through the galvanic isolator potentially corroding submerged metals on the boat. In this situation the shore power should be disconnected to avoid hull corrosion.

If the meter shows

  • PASS - Voltage is below 1.1V
  • FAIL - Voltage exceeds 1.1V
  • GREEN ZONE - indicates the galvanic isolater is blocking D.C. galvanic current
