Which Article addresses temporary installations in the National Electrical Code?

Article 590 of the National Electrical Code (NEC) specifically outlines the requirements for temporary installations. This includes guidelines for the safe installation and use of electrical systems that are not intended for permanent use, allowing for flexibility in various situations such as construction sites, fairs, or events where electrical power is needed for a limited duration.

One of the key attributes of Article 590 is that it addresses the challenges associated with temporary wiring, such as ensuring that it is safe and does not pose hazards to people or property. This article includes provisions for appropriate materials, methods, and specific practices that should be adhered to in order to maintain safety standards.

In contrast, other articles listed cover different aspects of electrical systems. Article 600 pertains to signs and outline lighting, Article 604 focuses on the requirements for remote control, signaling, and power limitation, and Article 620 deals with the requirements for elevators and escalators. Each of these articles addresses specific types of installations or applications that do not relate to the concept of temporary wiring, reinforcing that Article 590 is indeed the accurate reference for temporary installations.
