Where power and data cables are installed within the same containment system or within close proximity to each other, a barrier strip or other appropriate divider should be used.

power cable requires 12 inches of separation unless a listed barrier or separate raceway is used. The National Electrical Code establishes specific minimum distances when communications cables must run near power and light circuits. Proper installation can significantly reduce electromagnetic interference, prevent fire hazards, and improve overall efficiency. The NEC requires that cable trays must be supported by members at an interval specified by the cable tray manufacturer, but not more than 5 feet for horizontal runs to support the weight of the cables and other loads. Maintaining proper separation between power, data, and limited energy cabling is foundational to system performance, safety, and code compliance.
