Abstract
Supply of ac current from the marina source to the boat's DC loads is permitted only when an isolation relay completes the electrical circuit therebetween. A control means monitor the boats battery voltage, battery charger current and DC load current, and supplies operating current to the isolation relay only when those monitored conditions indicate a need for the supply of current from the on-shore source to the boat. The duration in which the on-shore ground lead is connected to the boat's ground system, a customary path for electrolysis currents, and corrosion damage caused by those currents, and the duration of consumption of on-shore electricity, are thus limited.
