Can air pipes be run inside cable trays

Home / 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.
