As required by NEC Article 300, what should be done for temporary wiring?

Temporary wiring must follow all permanent wiring rules to ensure safety and compliance with the National Electrical Code (NEC). While temporary installations may have specific provisions allowing for flexibility due to their nature, they still need to adhere to safety practices established for permanent wiring. This includes proper installation techniques, derating of conductors, grounding requirements, and appropriate protection from physical damage.

This adherence to the same standards as permanent wiring helps prevent hazards such as electrical shock, short circuits, and fire risks associated with improperly installed electrical systems.

Other options do not accurately represent the requirements of the NEC. For instance, leaving temporary wiring unprotected would significantly increase safety risks, and suggesting that temporary wiring is exempt from code requirements undermines the intention of the NEC to ensure safety in all electrical installations. Similarly, while temporary wiring may have time limits in practical scenarios, the fundamental requirement that it follows the same safety standards as permanent installations takes precedence.
