Fire cable tray support unit how many meters per unit

Fire-rated supports must be spaced to prevent risk of any cables encroaching into possible passageways, or otherwise be spaced no more than 1 metre apart. Note 1 - Fire-rated cable supports include screws, nails, anchors and clips, saddles, ties, cleats & similar. Note 2 - In all buildings. Although BS 7671 touches on the subject of cable supports, it does not detail specifically what these support distances should be. 8 (Other Mechanical Stresses (AJ)) in that document provides requirements for cable support. Vertical deviation: ≤3mm per meter. Must be level, plumb, and securely mounted on supports. Support spacing: The maximum distance between supports for cable tray systems, which varies based on the tray type, load, and. Specifying cable support for emergency power, fire alarm interfaces, smoke control equipment, or critical process wiring is different from buying a standard tray for a normal branch route. A fire resistant cable tray is selected when the project needs organized routing, clear identification.
