It's Only Temporary: Codes and safety still apply regardless of wiring's permanency

摘要

TEMPORARY WIRING IS NOT AN "ANYTHING GOES" SITUATION. Energized electrical systems and circuits, even if only temporary, present hazards for electrical workers and others in construction. Safe work practices should always be applied when working on temporary wiring. Electrical contractors should plan for the temporary wiring anticipated for each project. They are usually responsible for installing the permanent wiring during construction, and each project usually requires a minimum amount of temporary wiring that must be installed and used by all the trades. Temporary wiring must meet National Electrical Code requirements and be installed and maintained by qualified persons that apply safe work practices in compliance with industry standards. Article 590 provides minimum requirements for installing temporary electrical power and lighting.
