Isolators

Galvanic corrosion problems can occur when your boat is connected to shore power and low-voltage DC currents come on board via the shore power ground wire. Galvanic isolation through the use of a marine battery disconnect switch or boat battery isolator can help you avoid this problem and save you from experiencing damaging corrosion to your boat's underwater metal parts such as the propeller, shaft, etc.
