Which safety standard should be referenced when installing raceways?

When installing raceways, the National Electrical Code (NEC) is the primary safety standard to reference. The NEC provides comprehensive requirements and guidelines for the safe installation of electrical wiring and equipment in the United States. It ensures that raceways are installed in a manner that reduces the risk of electrical hazards, such as short circuits and fires. The code addresses aspects such as materials, bonding, grounding, and proper raceway sizing, all of which are crucial for maintaining electrical safety and system integrity.

While the other standards mentioned, including OSHA guidelines, focus on workplace safety and health regulations, and NFPA standards may cover broader fire prevention measures, the NEC specifically governs electrical installations, making it the most relevant standard when working with raceways. Therefore, for those engaged in electrical installations or assessments, familiarity with the NEC is essential for compliance and ensuring safety in their work practices.
