Dnk, 250.50 addresses grounding electrodes.
250.104 addresses bonding
of a water pipe, probably in the event that it is not eligible as a grounding electrode.
You are confusing your concepts.
250.52 States that a water pipe is PERMISABLE, does not state it is mandatory.
Open your book!
the grounding electrode. It doesn't state whether or not to use it at all. That is accomplished through 250.50.
I threw every argument you guys have tossed out there, and all it states is it SHALL be bonded to the Grounding Electrode System.
The whole PERMISSABLE thing cost me dinner.
Are you talking about 250.52(A)'s title?
It's meaningless when taken in context of 250.50's requirement.
Bob, Just because you bond something to a ground electrode system, that doesn't make that item a ground electrode, does it?
Because 250.50 directs us to bond the water pipe, this doesn't make that water pipe a ground electrode.
The water pipe's inclusion in 250.52(A) makes it a grounding electrode
, not a "bonding electrode", as if there is such a thing.
The title of 250.52 is "Electrodes Permitted for Grounding." This section's whole purpose for being is to create a Grounding Electrode System. How can you single out an electrode and say it's not really performing the same function as it's counterparts in (2) through (7)?
