So the rod serves as a backup ?What would happen without your ground rod if the neutral back to the transformer were to open? Does that help answer your question?
What ground rod are you talking about? The ground rod IS the neutral-earth bond at the service panel. Or are you talking about the ground rod at the utility transformer end?Hi Folks
If there is a neutral-earth bond at the service panels at our homes why do we need a ground rod if the fault current will flow back to the utlity transfomer trough the neutral and not trough the ground rod ?
Happy New Year : )
I meant the ground at the house/building not at the utility transformer, and for the fault current i mean an earth fault currentWhat ground rod are you talking about? The ground rod IS the neutral-earth bond at the service panel. Or are you talking about the ground rod at the utility transformer end?
What fault current are you talking about? There are lots of different kinds of faults. Which one or ones are you talking about specifically?

Then what you are asking can be restated as, "Why do we need a ground rod if there is a ground rod?"I meant the ground at the house/building not at the utility transformer, and for the fault current i mean an earth fault current
In some parts of the world the Neutral is not bonded to the earth ground at the panel, just back at the supply transformer, and the service Co. does not always supply a ground conductor anyway.If there is a neutral-earth bond at the service panels at our homes why do we need a ground rod if the fault current will flow back to the utlity transfomer trough the neutral and not trough the ground rod ?
