Minimum distance between cable tray layers
When installing two cable trays in parallel at the same height, the distance between them should be no less than 0. This spacing is crucial for adequate maintenance access, ease of inspection, and ensuring proper airflow for effective heat dissipation. Industry standards often recommend at least 300mm (12 inches) of spacing between power and control trays to minimize EMI. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require. Support spacing for cable trays must align with the manufacturer's instructions, as outlined in NEC 392. 8 (Other Mechanical Stresses (AJ)) in that document provides requirements for cable support. Clause 522-08-04 Where conductors or cables are not supported. The long and the short of it is that the ratio of the vertical spacing (e) to the external diameter of the largest cable (De) needs to be greater than 4 (i. e/De > 4) for there to be no derating (see Table 1 of IEC 60287-2-2).
