Cathodic protection (CP) systems are often a vital component of integrity management programs for oil sands facilities. The electrical components of these systems must be designed and installed in accordance with regional electrical codes, such as the Canadian Electrical Code (CEC) or the National Electrical Code (NEC). The CEC and NEC include limited direction on the electrical requirements for CP systems. This paper examines installations of typical CP components and suggests ways in which the CEC and NEC can be interpreted. It is demonstrated that interpretation of electrical requirements for CP systems can be difficult. To help improve compliance and understanding, future revisions of these codes should provide additional guidance for the design and installation of CP systems.
