How far is the air duct from the cable tray
The vertical safety distance should generally be no less than 300 mm between the top of the cable tray and the bottom of the ventilation duct. This spacing is important because it: In real installations, insufficient spacing often leads to airflow restriction and maintenance. An air duct is a sealed conduit that forms the critical pathway of a building's Heating, Ventilation, and Air Conditioning (HVAC) system. Its purpose is to transport air—whether it's conditioned (heated or cooled), fresh for ventilation, or exhaust for extraction. Think of the air duct system as. 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. AS/NZS 3000 and AS 3013 set the rules for how far cables must sit from other services, how often you. 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.
