What regulation limits the use of cable tray systems in hoist ways or areas susceptible to severe physical damage?

The regulation that limits the use of cable tray systems in hoist ways or areas susceptible to severe physical damage is outlined in 392.12. This section of the National Electrical Code (NEC) addresses the installation requirements for cable tray systems, particularly emphasizing locations where physical damage is a concern, such as hoist ways. By specifying these limitations, the regulation ensures that cable trays are installed in a way that minimizes the risk of damage to the cables they contain, which is essential for both safety and proper functioning of the electrical system. This focus on protecting cable infrastructure in high-risk areas helps prevent potential hazards and maintains the integrity of the electrical installations.
