Fire safety electrical cables should not be placed in cable trays
If not designed and installed properly, wiring inside cable trays may pose hazards such as fire, electric shock, and arc-flash blast events. Where cables pass through shafts, walls, slabs, or enter electrical panels or cabinets, openings shall be tightly sealed with firestopping materials in accordance with. Safety of a cable tray is not a matter of compliance with codes, but a matter of saving human life and billions of dollars' worth of infrastructure. Poorly fitted trays may serve as a fuse in case of a short or a top chimney in case of a fire. This manual will offer practical engineering knowledge. Cables that are supplying safety circuits shall have a resistance to fire rating of either the time authorized by regulations for building elements or British Standards for the circuits or one hour in the absence of such a regulation or standard. Cable trays can be part of a planned cable management system to support, route, protect, and provide a pathway for cable systems.
