Cathodically protected structures often require seemingly incompatible requirements. Ideally, a cathodically protected system should be isolated; yet if the system contains electrical equipment, it must also be grounded. Isolation and grounding are conflicting demands inherent in any system that contains electrical equipment and uses cathodic protection (CP) to mitigate corrosion. Cathodic protection of many structures can be greatly simplified by the proper use of direct current (DC) isolating/alternate current (AC) coupling devices. An example is DC isolation of cathodically protected structures from electrical grounding systems while retaining AC continuity with those systems as required by electrical codes.
