What is the primary focus of Article 669 in the National Electrical Code?

The primary focus of Article 669 in the National Electrical Code is on electrically driven or controlled irrigation machines. This article provides specific requirements and guidelines for the safe installation and use of electrical equipment in irrigation practices. The importance of this article lies in ensuring that irrigation systems operate safely and efficiently, particularly since these systems often involve motors and control devices that require careful attention to electrical safety and proper installation techniques.

In relation to other articles, such as those that pertain to industrial machinery or electroplating, Article 669 is distinctly aimed at agricultural applications and practices involving irrigation, which emphasizes the unique considerations involved in those systems. Similarly, while there are articles that cover aspects of water and its relationship to electrical systems, Article 669 specifically addresses the irrigation context, ensuring that practitioners in agriculture have clear electrical safety standards to follow.
