The maximum allowable voltage drop at 100% of the galvanic isolator ampacity rating should not exceed 2.5 volts. This standard is important because it ensures that the system operates efficiently while minimizing energy losses and potential overheating. A well-installed galvanic isolator helps to prevent galvanic corrosion by blocking stray currents that can harm metal components in a marine environment. If the voltage drop exceeds this limit, it could indicate that the isolator is not functioning optimally, possibly leading to safety issues and increased wear on the electrical system. Maintaining a voltage drop within this limit helps to ensure reliable operation and performance of marine electrical systems.
