NEC Interpretation Regarding Temporary Walls

The National Electrical Code (NEC) does not explicitly address the use of extension cords in temporary walls. However, it does provide guidance for the installation of electrical wiring in temporary structures

Section 590.4(D)(4)

: "Wiring methods shall be installed in accordance with the provisions of this article."This section essentially requires that all electrical wiring, including extension cords, be installed according to the NEC requirements for the specific application.

Section 110.14(C): "Flexible cords and cables shall be used only for the following:" Pendants Wiring of fixtures Connections to portable appliances Elevator cables Wiring of cranes and hoistsExtension cords are specifically mentioned as allowable for connecting portable appliances.

Temporary Walls vs. Permanent Walls

The NEC defines permanent walls as "Walls supporting a roof or portions thereof." Temporary walls, on the other hand, are not specifically defined, but can be interpreted as walls that are not intended to be a permanent part of the structure.In your situation, the reconfigurable cubicles and walls could be considered temporary. However, it is important to note that the NEC does not make a specific distinction between temporary and permanent walls.

Recommendations

To address the concerns of the fire marshal, consider the following recommendations: Use Listed Extension Cords

Ensure that all extension cords used are listed and approved for use in the intended location.

Inspect Regularly

Regularly inspect extension cords for damage or wear. Replace damaged cords immediately.

Securely Mount Cords

Secure extension cords to the walls or floor to prevent tripping hazards and ensure that they are not exposed to sharp edges.

Limit Use

Use extension cords only for temporary purposes, such as connecting portable appliances or devices that are not permanently installed.

Consider Alternate Solutions

Explore alternative solutions such as installing permanent electrical outlets in the cubicle walls or using cord management systems to eliminate the need for extension cords.

Conclusion

While the NEC does not explicitly address the use of extension cords in temporary walls, it requires that all electrical wiring be installed safely and in accordance with the code requirements. By following the recommendations above, you can address the concerns of the fire marshal and ensure the safety of your employees and workplace. Flag for review
