If the raceway is run overhead in the machine room, a clear headroom of how many feet must be maintained?

Maintaining a clear headroom of 7 feet when running raceways overhead in the machine room is crucial for several reasons. This height requirement ensures safety for personnel working in the machine room, allowing for adequate clearance to move around without the risk of bumping into overhead equipment or raceways. Additionally, having sufficient headroom supports proper maintenance and inspection of installed equipment, enabling technicians to have full access to necessary areas for both operation and troubleshooting.

This standard is commonly referenced in codes and regulations pertaining to electrical fixtures and equipment, emphasizing the importance of safety and accessibility in machine environments. By adhering to this height requirement, one can minimize hazards and promote a safe working atmosphere.
