You're just talking chronologically right.ICE said:Years ago, when I was just a kid,
Well since 250.52(A)(3) requires the CEE to be encased in 2" of concrete, the portion stubbed up out of the concrete is no longer an electrode, it becomes a grounding electrode conductor. Violation of 250.62.gfretwell said:I have really not heard a good reason why the turned up rebar is a bad idea.
Not around here.chris kennedy said:Well since 250.52(A)(3) requires the CEE to be encased in 2" of concrete, the portion stubbed up out of the concrete is no longer an electrode, it becomes a grounding electrode conductor. Violation of 250.62.
so what do you call that piece of wire that goes from the grounding electrode piece of rebar to the panel? i don't see a violation here,move on.chris kennedy said:Well since 250.52(A)(3) requires the CEE to be encased in 2" of concrete, the portion stubbed up out of the concrete is no longer an electrode, it becomes a grounding electrode conductor.

Why that would be the GEC. Does the rebar stubbed up out of the concrete meet the requirements of 250.52(A)(3) or the requirements of 250.62? Not as the code is currently written. Do I think this is a big issue? No I don't, yet the code says what it says, read carefully then read again.pwood said:so what do you call that piece of wire that goes from the grounding electrode piece of rebar to the panel? i don't see a violation here,move on.

A concrete-encased electrode shall consist of at least 6.0 m (20 ft) of either (1) or (2):chris kennedy said:Well since 250.52(A)(3) requires the CEE to be encased in 2" of concrete, the portion stubbed up out of the concrete is no longer an electrode, it becomes a grounding electrode conductor.

How does the part of the rebar exiting the concrete meet the requirements of a CEE???Gregg Harris said:(3)Chris, what part of this determines that the rebar turned upwards and bonded above ground dictates that the vertical section is to be determined to be the "Grounding Electrode Conductor"?
As long as at least 20 feet of it is encased in at least 2 inches of concrete is where the grounding in direct contact with the earth will take place. Nothing precludes that when it exits the concrete it will no longer conduct.
You should consider it the GEC and it meets the requirements of 250.62 doesn't it.Should we consider a water line in contract with at least 10 feet of earth that where it exits, it then becomes the Grounding Electrode Conductor?
Your water pipe would fit the description of a bare copper conductor would it not?250.62 Grounding Electrode Conductor Material. The grounding electrode conductor shall be of copper, aluminum,
or copper-clad aluminum. The material selected shall
be resistant to any corrosive condition existing at the installation
or shall be protected against corrosion. The conductor
shall be solid or stranded, insulated, covered, or bare.
Chris are you saying that I cannot have a 10 foot ground rod that is driven in 9' with one foot sticking out of the ground and my GEC connected to this pipe is not compliant....?chris kennedy said:Well since 250.52(A)(3) requires the CEE to be encased in 2" of concrete, the portion stubbed up out of the concrete is no longer an electrode, it becomes a grounding electrode conductor.

It is not in the code but there was an ROP (report on Proposal) that stated this as an responseDennis said:Chris are you saying that I cannot have a 10 foot ground rod that is driven in 9' with one foot sticking out of the ground and my GEC connected to this pipe is not compliant....?Same scenario... I believe you are incorrect but I will look for the wording when I get a sec
Panel Statement: Only the portion of an electrode that is in contact with the earth can be called an electrode. The exposed portion of the rebar could be used as a connection point but cannot be considered as the electrode.

My father worked on a particle accelerator that had copper tubes for conductors. Water was fed through the tubes to keep them from melting.Gregg Harris said:It is already listed as a Grounding Electrode under 250.52250.52 Grounding Electrodes.
(A) Electrodes Permitted for Grounding.
(1) Metal Underground Water Pipe. A metal underground water pipe in direct contact with the earth for 3.0 m (10 ft) or more (including any metal well casing bonded to the pipe) and electrically continuous (or made electrically continuous by bonding around insulating joints or insulating pipe) to the points of connection of the grounding electrode conductor and the bonding conductor(s) or jumper(s). if installed.
The conductor shall be solid or stranded, insulated, covered, or bare. It does not say hollow. So in sizing it for the Grounding Electrode Conductor using 250.66 what size would it be listed under?
Francis Good example of "access" It is hard to tell from the picture, but the bonding conductor should be at the base of the acorn opposite of the set screw. It appears to be on the side.Francis Vineyard said:250.68 & 250.70 This method has been approved when it is not subject to corrosion. How often do you see the metal post or columns in basements and garages; including braced wall steel devices taken advantage of as a grounding electrode per 250.52(A)(2) items (2) & (4)?
