Confused, confounded and puzzled are terms found throughout this forum about NEC code regarding “grounding”.
We are conditioned to believe that there is object; “the ground” that is electrically quiet, safe and always zero volts and could never be a party to harming anyone or damaging our equipment.
The authors of NEC code certainly want us to believe that, but their frequent updating, changing and sometimes seemingly contradictory requirements can only lead one to wonder if is there more to the ground than they care to share.
The ground is zero volts right! But relative to what? The ground.
If you had very long meter leads and placed one on your ground rod and the other on someone’s a mile away would your meter read zero?
I am starting this discussion in hope of clearing up some of the mystery regarding grounding and possibly help people develop grounding systems that meet code and protect their equipment as best as possible.
