A Galvanic isolator works by creating a high resistance pathway for Galvanic Corrosion currents. This stops the Galvanic current from flowing through the boat's hull, anodes, etc., which prevents them from corroding. It really is that simple!
Here is a more detailed explanation of how a Galvanic isolator works:
When a boat is connected to shore power, there is a small potential difference (Voltage) between the boat's hull and it's surroundings. This potential difference can create an electric current, known as a "Galvanic" current which is a flow of electrons from (the boat's hull) to the shore or nearby metalwork, such as other boats, pontoons etc. This Galvanic current can cause the boat's hull and underwater metalwork, such as outdrives, to corrode.
A Galvanic isolator works by introducing a high resistance in the path of the Galvanic current. This high resistance prevents the current from flowing through the boat's hull. The Galvanic isolator. The galvanic isolator is designed to block small (Galvanic) currents, but allow any earth fault currents to flow normally, so the electrical safety of the boat isn't affected.
Galvanic isolators are an essential device for any boat that is connected to shore power. They can prevent costly and time-consuming repairs and can help extend the life of the boat. Fitting a plug in Galvanic isolator takes a few seconds, and no tools or electrical knowledge are needed.
