According to standards, how must galvanic isolators be marked if they are not installed in machinery spaces?

Galvanic isolators must be clearly marked to ensure that they can be easily identified and understood by users and technicians, especially when they are not installed in machinery spaces. The marking provides essential information about the device’s purpose, capabilities, and compliance with relevant safety standards. This is crucial in promoting safety and functionality within electrical systems on vessels.

These markings allow for quick identification during inspections or maintenance and help ensure that the isolators are correctly understood in their application, especially in preventing galvanic corrosion. While other terms may come to mind when considering the function and purpose of galvanic isolators, the specific requirement is that they must indeed be "marked" to maintain compliance with established standards. This ensures that anyone who interacts with the equipment can quickly discern what it is and how it should be maintained or serviced.
