Can air pipes be run inside cable trays

Can air pipes be run inside cable trays

Question 1: Can mechanical utility piping or tubing containing water or compressed air be installed in cable trays with electrical cables? Answer: No. Cable trays are a support system for electrical cables, power, signal, and communication and optical fiber cables. Section 318-4 Uses Not Permitted states that "Cable tray systems shall not be used in environmental air spaces except as permitted in Section 300-22 to support wiring methods recognized for use in such spaces. Is anyone aware of a code stating that it is acceptable, or unacceptable, to run air supply tubing inside a wireway along with 480VAC, 3-Phase wires? My concern is that the air tubing may contain moisture and if it were to break water could get on the wires. This would severely obstruct airflow, violate building regulations, and create an extreme fire hazard.

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.
