Hello all,
I am doing the earthing for date centre , as shown in the attached drawing, we have four racks each of which is fed from a different source ( different DBs and switchboards), can someone show how the earthing can be done? With this be affected by the fact that each rack is fed from two sourches? Can we have for example one earthing par with different cables connected to the each rack and connect this to A or B? please note in my case I have more than 100 racks and only showing this as an example. All these racks are fed from both sources, do I need one earthing bar per say 5 racks and then connect all the bars together and then take them back to either of the switchboards?
