Some factories use multiple earthing rods to increase protection. This can be a good idea, but only if done right.
Each rod must be connected properly and placed at the right distance. If not, it can cause grounding issues.
In large projects, using more than one rod helps spread the electric load and provides better safety. Just make sure they are tested and maintained regularly.
In Karachi’s large industrial zones, this practice is common. Always consult an expert before installing multiple rods.
