In an impressed current cathodic protection (ICCP) system, the positive terminal of the power supply is connected to the anodes. This configuration is fundamental to ICCP operation, where the anodes are typically made of materials like titanium, which are placed near or in contact with the structure being protected.

Connecting the positive terminal to the anodes allows for a controlled flow of direct current from the anodes through the electrolyte (usually soil or water surrounding the structure) to the cathodes, which represent the structure being protected from corrosion. The current flow mitigates the corrosion process by supplying electrons to the cathodic areas.

This understanding of the circuit design is crucial for those working in cathodic protection, as it illustrates the direction of current flow and the roles of the different components in the system. The connection of the power supply is integral in ensuring that the system operates efficiently to provide effective corrosion protection.
