The maximum current through a galvanic isolator is specified to not exceed what value for 1 volt at a temperature of 25°C?

A galvanic isolator is designed to prevent galvanic corrosion in marine electrical systems by isolating the DC systems from AC ground while allowing AC current to flow in a controlled manner. The specification regarding the maximum allowable current through a galvanic isolator is crucial for ensuring it operates effectively without compromising safety or functionality.

In this instance, the correct answer indicates that the maximum current through a galvanic isolator at 1 volt and a temperature of 25°C should not exceed 0.03 amperes. This limit is in place to balance safety with performance, allowing enough current to flow to handle ground fault conditions without risking corrosion or damage to connected systems.

By adhering to this limit, installers ensure that the galvanic isolator maintains its effectiveness in preventing unwanted galvanic currents while remaining within the operational parameters that guarantee both electrical reliability and system safety.
