Zinc Saver


If the dock cord green wire is attached to your bonding system for better A.C. safety grounding (an ABYC recommended connection) and another boat in the area has an A.C. green to bonding connection, you have formed a battery. The higher voltage boat (yours 800 - 900 millivolts) will lose zinc towards the dock (200 millivolts) and to all other lower bonding system voltage boats in the general area with the green wire A.C. to their bonding systems.

The Zinc Saver installed between A.C. green wire system and D.C. bonding system stops zinc loss to other boats and to the dock while maintaining A.C. safety ground protection.
