Karl take care friend and I to wish you a speedy recovery Rev. 21:4 :) but this grounding is a touchy subject, but I'm still learning even with over 22 years in the trade, and you know our trade one day its :( and then :D
 
Re: Grounding Thought Experiment

My understanding is that the waterline must be supplemented because it may go away. The copper pipe may be replaced with plastic and the plumber does not realize that he has eliminated the grounding for the structure. I guess it is assumed that if someone pulled up a ground rod they would know they have affected the grounding. Keep in mind that a single ground rod with a resistance above 25-ohms must be supplemented by an additional ground (usually another rod).
