In dual shore power cord applications, the current rating of the galvanic isolator must not be less than what?

In dual shore power cord applications, the current rating of the galvanic isolator must not be less than the sum of the ratings because the galvanic isolator is responsible for preventing galvanic corrosion by allowing AC current to pass through while blocking unwanted DC components. When two shore power cords are used, each cord may be supplying power at the same time. Therefore, the isolator needs to be able to handle the total current that might flow through it from both sources, which means it must accommodate the combined ratings of both shore power cords. If the isolator's current rating is less than this sum, it could overheat or fail, which poses risks to the overall electrical system and safety of the vessel. This requirement ensures that the isolator remains effective in protecting against electrical issues while also maintaining the safety and integrity of the power system.
