Should rooftop cables be run in cable trays or conduits

Those systems ensure the effectiveness of the cables they protect, reduce wear and tear to rooftop installations, and help ensure safety for people, as well as, property. 1) Use Cable Trays! The first and most obvious of these best practices is that you should always use cable. Tray cables (TC, TC-ER, and similar types) are specially designed for use in cable tray systems, which support multiple runs of cable across industrial and commercial buildings. In order to do that, we employ the use of various mechanisms such as conduits, trays, and pits to contain the wires.

Vertical spacing requirements between cable trays and pipes

Vertical spacing requirements between cable trays and pipes

In general, vertical spacing for cable trays should be 30 cm (12 in), measured from the bottom of the upper tray to the top of the lower tray. The spacing between trays, whether horizontal or vertical, depends on various factors like cable type, environment, and tray material. Proper installation can significantly reduce electromagnetic interference, prevent fire hazards, and improve overall efficiency. Although BS 7671 touches on the subject of cable supports, it does not detail specifically what these support distances should be. The cable tray is installed in parallel with the general process pipe (such as compressed air pipe) not less than 400 mm.
