Why It Matters: High‑voltage and limited energy circuits routed too closely can cause cross‑talk, distortion, or packet errors, especially in dense cable trays or congested ceiling spaces. Tray Type and Material Selection Indoor: Painted steel or galvanized trays. Outdoor: Hot-dip galvanized or. Although the type of cable and conductor is the determining factor in the fire behaviour of ducts and conduits, the choice of cable tray type and the installation of the latter in line with installation precautions are just as crucial. Cables are very rarely the source of a fire. smoke control fans, firefighter telephones). Data and signal cables should. If not designed and installed properly, wiring inside cable trays may pose hazards such as fire, electric shock, and arc-flash blast events. Cable trays can be part of a planned cable management system to support, route, protect, and provide a pathway for cable systems. Best Practice: Use separate trays, conduits, or divider systems to isolate voltage classes.
