I would like to put a little debate back in this thread if I might.
We are told in 250.32(A) Where there is no existing grounding electrode, the grounding electrode(s) required in 250.50 shall be installed.
Now let’s look at 250.50.
250.50 Grounding Electrode System.
All grounding electrodes as described in 250.52(A)(1) through (A)(6) that are present at each building or structure served shall be bonded together to form the grounding electrode system. Where none of these grounding electrodes exist, one or more of the grounding electrodes specified in 250.52(A)(4) through (A)(7) shall be installed and used.
Here we are told to bond any electrode found in 250.52 together and if none are present to install one that is outlined in (A)(4) through (7).
After reading both of the sections as referenced to from 250.32 I can not find anywhere that it says to keep going to 250.53 nor 250.56. With out being referenced to go there I ONLY need to fulfill what is mandated by 250.32(A).
So when gfretwell Made the statement to bury 10 foot of pipe and call it an electrode he was not to far from wrong. If the last 10 foot of water line was metal pipe then he would be right simply due to the fact that 250.32(A) only refers to 250.50 and neither 250.32, 250.50 nor 250.52 refers to any other section.
A proposal has been submitted to have the reference in 250.32 changed from 250.50 to part III of 250 for the 2008 cycle.
