Two cables should not share the same cable tray

Home / Two cables should not share the same cable tray

When dealing with any mixture of cables, it is crucial to follow the National Electrical Code (NEC) regulations, specifically 392. These systems provide an efficient and adaptable solution for managing a wide range of cables, including power cables, control cables, Ethernet, and fiber optic lines. Cable tray barriers can be used to separate conductors operating over 600 volts from other conductors in the same tray operating at 600 volts or less. It doesn't sound like you're in the US, but here in US, this is acceptable provided all of the insulation is rated for the highest voltage in the tray. 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.
