What is the maximum distance between vertical raceway supports?

1. 10 feet

2. 12 feet

3. 15 feet

4. 20 feet

The correct answer is: 10 feet

The correct maximum distance between vertical raceway supports is 10 feet. This standard is generally established to ensure that wiring or conduits are securely supported and protected from physical damage, which is crucial for maintaining system integrity and safety. In vertical installations, spacing supports too far apart may lead to sagging of conductors or raceways, increasing the risk of mechanical strain and potential failure. By adhering to the 10-foot maximum, you ensure that the raceways remain stable, minimizing any risk associated with excessive bending or movement. Other distances listed, such as 12 feet, 15 feet, or 20 feet, would not provide adequate support for vertical raceways and could compromise the system's safety and performance.
