Why is it important to secure raceways at specified intervals?

Securing raceways at specified intervals is crucial to ensure stability and compliance with code requirements. When raceways are secured properly, they are less likely to sag or move, which helps maintain the integrity of the electrical system. This stability is essential for both safety and functionality, as loose or improperly supported raceways could lead to physical damage or create a hazard due to exposure of conductors.

Moreover, various electrical codes and standards outline specific requirements for the spacing and securing of raceways to ensure safe installation practices. Compliance with these codes not only helps avoid potential safety risks but also ensures that the installation passes inspections, thus validating that the work meets accepted standards for electrical systems.

In contrast, while enhancing visual appeal, decreasing installation time, or preventing rust formation might seem important in certain contexts, these aspects do not address the fundamental need for support and adherence to safety regulations that secure raceways fulfill.
