What this video covers

The electrical system upgrade on this vessel focuses on a multi-tiered AC charging setup designed to handle diverse international shore power standards. The installation utilizes a Victron MultiPlus inverter-charger for high-amperage 230V shore power, supplemented by two smaller Victron smart battery chargers capable of accepting 120V to 240V at 50Hz or 60Hz.▶ 3:16 To mitigate galvanic corrosion, the system incorporates a galvanic isolator on the shore power ground line rather than a heavy isolation transformer.▶ 1:32 The crew installed an RCBO (residual current breaker with overcurrent protection) to provide ground fault protection for the entire AC circuit.▶ 0:46 During the installation, the owners opted to use tinned, stranded copper wire for AC runs, adhering to the more stringent ABYC guidelines rather than the European ISO standards, which permit standard stranded copper in watertight enclosures.▶ 13:08 The project concludes with the successful verification of 230V shore power input, though final completion of the AC distribution box awaits the arrival of specific breakers from Norway.▶ 28:47
