What this video covers

Jeff Cote of Pacific Yacht Systems advises owners of a Grand Banks 36 Classic upgrading from 30-amp to 50-amp shore power to install a fail-safe galvanic isolator.0:25 When selecting a unit, ensure the device rating matches or exceeds the boat's shore power amperage.0:29 Prioritize models that fail in a closed circuit to maintain the integrity of the AC grounding connection.1:04 Older galvanic isolators often failed in an open state, which effectively disconnected the boat's AC ground and created a safety hazard.2:26 A fail-safe isolator prevents this loss of ground during power surges or lightning strikes while protecting underwater metals from stray current corrosion.1:53 Always verify the specific amperage requirements of the shore power system before purchase, as some manufacturers offer units compatible with both 30-amp and 50-amp configurations.0:45
