How often should horizontal raceway runs be supported?

Horizontal raceway runs should be supported at intervals not exceeding 5 feet. This requirement ensures that the raceways are securely anchored, minimizing the risk of sagging, stress on connections, and potential damage to the wiring contained within. Proper support is essential for maintaining the integrity of the pathways that hold electrical conductors, as it helps to prevent movement that could lead to wear or electrical hazards.

In defined standards, specific distances for support are established based on the type of raceway, the materials used, and the load they carry. By adhering to the 5-foot requirement for horizontal runs, installation practices contribute to safer and more reliable electrical systems, which is a fundamental aspect of electrical construction and maintenance. This regulatory measure is designed to promote both safety and performance, ensuring that all systems function as intended over their operational lifespan.
