What is the rule regarding the use of extension cords as permanent wiring?

The rule regarding the use of extension cords as permanent wiring is clear: extension cords cannot be used as a substitute for permanent wiring. This guideline is put in place to ensure safety and compliance with electrical standards. Extension cords are designed for temporary use and are not intended to provide a long-term solution for electrical distribution.

Using extension cords in place of permanent wiring can lead to several hazards, including overheating, increased risk of electrical shock, and fire hazards due to their potential to be improperly used or damaged over time. Furthermore, permanent wiring systems are installed according to specific electrical codes, which ensure they can handle the load and are installed safely and securely within structures.

Permanent wiring is designed to be durable and is installed by qualified personnel to ensure compliance with safety regulations. In contrast, extension cords typically lack the same level of protection and fail-safe measures that a properly installed permanent wiring system provides. Therefore, the National Electrical Code emphasizes the importance of using extension cords only as intended, reinforcing that they should be utilized for temporary connections only. This approach prioritizes safety and promotes adherence to established electrical standards.
