I will probably ask my local inspector this but I get alot of panel upgrade request. I have not done any since I was an apprentice since I have spent most of my career in commercial and industrial.
I have looked at one panel so far and noticed that they ground the neutral to the copper water lines in the house. (Not the main coming in but the 1/2" cold water line)
Do you residential guys establish a new ground with a plate or rod when upgrading old fuse panels or is it even required since it is existing?
