Cable trays and busways at floor level or at slab penetrations shall have a waterstop no less than 50 mm in height. At slab penetrations, provide 20–30 mm of firestopping and install a fire-support plate at the top. Cable tray installation must comply with specific technical standards to ensure electrical safety, system reliability, and long-term maintainability. This document outlines the key requirements for cable tray layout, installation, and fireproofing in industrial and commercial environments. The following charts give the number of 3M pillows needed to completely firestop an opening that cable tray passes through.
