Galvanic Isolators

A range of galvanic isolators (also known as Zinc Savers) rated at 16 or 32 amps.

The galvanic isolator prevents electrolytic corrosion. It blocks low voltage DC currents that enter your boat via the shore power earth wire. These currents can cause corrosion to the boat’s underwater metals, such as the hull and prop shaft, and can increase wear on zinc anodes.
