Personnel assigned to obtain voltage and current output readings from a rectifier must have knowledge comparable to ________.

The appropriate level of knowledge required for personnel who need to obtain voltage and current output readings from a rectifier aligns with the standards outlined by NACE Certification Level CP1. This certification focuses specifically on corrosion prevention and control practices, specifically for cathodic protection systems, which includes rectifiers used in such applications.

Individuals with NACE CP1 certification possess a comprehensive understanding of cathodic protection principles, equipment, and the troubleshooting processes required to ensure effective operation. This knowledge is essential when taking voltage and current measurements to assess the performance of rectifiers, as it ensures proper interpretation of data and emphasizes safety and accuracy in handling electrical components and systems related to corrosion control.

In contrast, while familiarity with ANSI accreditation, NFPA standards, or journeyman electrician classifications may provide useful electrical knowledge, they do not specifically encompass the corrosion control aspects that are crucial for those working with rectifiers in the context of pipeline integrity and corrosion prevention. Therefore, NACE Certification Level CP1 is the most relevant qualification for this task, emphasizing specialized skills and knowledge in cathodic protection.
