Can ENT be installed beneath a raised floor for information technology equipment according to the NEC?

Installing electrical raceways like ENT (Electrical Nonmetallic Tubing) beneath a raised floor for information technology equipment is permissible according to the National Electrical Code (NEC). The code allows for the use of ENT in areas that may involve both electrical and data communications, provided it is installed in compliance with NEC requirements.

One key aspect of using ENT is that it must be adequately supported and maintained to prevent damage and ensure safety. When installed properly, ENT under raised floors can offer a neat and organized solution for routing electrical wires, minimizing clutter and reducing electromagnetic interference, which is crucial in IT environments.

The acceptance of ENT for this application aligns with modern practices in data center design, which often utilize raised floors for cable management and airflow. Thus, the proper application of ENT not only adheres to safety standards but also enhances the overall efficiency of the installation in critical IT infrastructures.
