Is there a BS code reference to the minimum allowable distance that a cable tray must be installed when placing the new tray system on top of another existing tray system? (i mean stacking)

Hi Kumarm

There is some guidance in Table 4C4 of BS7671 and suggests a minimum of 300mm however please note that it also states that the existing and new cable current carrying capacity will need to be de-rated as the ventilation is significantly reduced (depending on the number of cables, configuration etc).

To make life easier I would avoid stacking if you can!
