No, we don't sell life jackets, but we protect your safety at sea by being the best in the business when it comes to every aspect of marine electric. We inspect vessels, evaluate corrosion damage and produce comprehensive reports of our findings. We also provide detailed estimates of necessary equipment replacement and repairs. ELECTRICAL We examine your boat's electrical systems for insurance requirements, fire and water damage, safety and buyer protection purposes and assurance of compliance with applicable electrical standards such as ABYC and NFPA 302, or different classification societies' rules such as ABS, Lloyd's Registry and Bureau Veritas. CORROSION Through testing we determine specific corrosion damage areas and make recommendations for corrections while insuring that there are proper potential levels for cathodic protection with no stray current leakage problems. Solution: The Galvanic Isolator, designed and manufactured by Ward's Marine Electric, is built to comply with ABYC A-28 Galvanic Isolators. Vessels with aluminum or steel hulls are subject to galvanic corrosion (electro-chemical action) when the hulls are electrically connected to the shore power ground. The galvanic isolator is designed to protect aluminum and steel hulls and aluminum outdrives as well as zinc anodes from accelerated galvanic corrosion that generally occurs when a boat is plugged into shore power. When a shore power connection is made, the galvanic isolator blocks the DC corrosion currents that result from a path that is completed through the equipment ground (green safety ground). At the same time, the integrity of the equipment ground is maintained which protects against the danger of electrical shock. The grounded hull not only decreases the hull potential level but also increases the sacrificial loss of the zinc anodes resulting in more frequent replacement expense. The galvanic isolator, by preventing current loss to the dock, will increase the life expectancy of the sacrificial zinc anodes with less haul out. Installation is simple. No special tools are required. The unit is mounted to a bulkhead with four screws and is wired in series with the equipment grounded before entering the main AC distribution panel.
