Could you someone please advise whether there are any guidance related to grounding/earthing cable routing inside the control cabinets room?
1) Is it allowed to route instrument/plant earthing cable in the same tray with instrument cables (non-I.S, 24V)? The instrument cable have screen and armour. If not what shall be the minimum distance?
2) Is it allowed to route instrument and plant earthing cables (insulated) in same cable tray?The cables are going to be route from control cabinets to the instrument and plant earth busbar in the control room. If not what shall be the minimum distance between instrument and plant earthing?
Plant earthing cables and instrument earthing cables are going to be connected to plant earth busbar and instrument earth busbar respectively.
