What does NEC Article 300 specify regarding raceways?

NEC Article 300 emphasizes the importance of secure installation when it comes to raceways. This requirement ensures that raceways are properly anchored to prevent movement and damage, which could lead to hazardous situations, such as exposure of wiring or disconnections. Secure installation helps maintain the integrity of the electrical system and protects against potential physical stresses and environmental factors that might affect the raceways over time.

While other aspects of raceway installation are also relevant, such as the materials used (which are not limited to PVC) and considerations for visibility, the focus on secure installation is crucial for safety and compliance with the National Electrical Code's broader goals. Properly supporting and securing raceways protects not only the raceways themselves but also ensures that electrical systems operate safely and effectively.
