What does NEC Article 300.38 detail regarding exposed cables?

NEC Article 300.38 specifically addresses the need for protection methods for exposed cable installations. This provision is crucial to ensure the safety and integrity of electrical installations, as exposed cables can be susceptible to physical damage, environmental factors, and accidental contact. The code outlines various acceptable methods to protect these cables, including using raceways, conduits, or suitable mechanical protection systems.

By mandating these protection methods, the NEC aims to mitigate risks such as electrical fires, shock hazards, and potential interruptions in service that could arise from damage to unprotected cables. The emphasis on protection reflects the importance of maintaining safe working conditions around electrical installations, ensuring that proper measures are taken to secure exposed cables from any vulnerabilities they may face in their operational environment.
