Are flexible cords considered permanent wiring according to the NEC?

• A. Yes, they are permanent wiring
• B. No, they are usually considered temporary wiring
• C. Only in specific installations
• D. Yes, if properly installed

Answer: (B)

Flexible cords are typically not categorized as permanent wiring according to the National Electrical Code (NEC). Instead, they are generally viewed as temporary wiring solutions that are designed for short-term use or mobility. This classification is primarily due to the inherent characteristics of flexible cords, which allow them to be moved, repositioned, or disconnected easily from power sources. Flexible cords are intended for applications where equipment connected to the cord may need to be frequently relocated or is not permanently affixed. This temporary nature is important for safety and compliance, as permanent wiring installations require different construction and installation practices that provide a higher level of safety and durability. Furthermore, the NEC outlines specific requirements for the installation and use of flexible cords to ensure they’re used safely and appropriately. This includes restrictions on where and how they can be used, emphasizing that they should not replace fixed wiring in permanent applications. The code distinguishes between temporary and permanent structures, impacting how different types of wiring methods are implemented in various settings.
