For information on Fixed Electric Heating Equipment for Pipelines and Vessels, refer to which article?

The correct reference for information on Fixed Electric Heating Equipment for Pipelines and Vessels is found in Article 426 of the National Electrical Code (NEC). This article specifically addresses the requirements for electric heating equipment used in various applications, including pipelines and vessels.

Article 426 outlines the design, installation, and maintenance requirements to ensure safety and efficiency in the use of electric heating for controlling the temperature of liquids in piping systems. This is particularly important in contexts such as preventing freezing or ensuring the proper viscosity of materials transported through pipelines.

The focus of Article 426 on fixed electric heating equipment distinguishes it from other articles that cover different areas of electrical installations. For instance, other articles address general motor installations, branch circuits, or specific types of electrical equipment, but do not specifically tackle the unique considerations associated with heating elements used in pipelines and vessels.
