NEC states the grounding electrode conductor must be a continuous unbroken conductor unless assembled with a non reversable crimp. At what point does this grounding electrode conductor end?
I was under impression that the conductor between the rods or rod and metal pipe/other building grounding system is still called grounding electrode conductor?
I would have to argue that, perhaps only by intent, the jumper itself is still bound to being continuous or irreversibly spliced.Nope, the GEC ends at the electrode. The connection between two electrodes is made by a bonding jumper and therefore does not have to be continuous or irreversibly spliced.

250.53(C) sends us to 250.64(A), (B), and (E)... skipping over 250.64(C)... so it is not required. But that doesn't negate intent, does it? But I will agree that any such intent is expressed very obscurely :roll:Read 250.53(C). Still feel that way?

Yes, you did :grin:I guess I missed the joke.
Whose intent... not sure what you are saying. The code clearly states it does not need to be continuous but you say the intent is for it to be continuous???
Disclaimer: I am not the former electrician turned inspector George is refering to!Smart, I'll put it this way. Around here, I'd never expect to get away with it, so I'd never try; but the code is pretty clear in it's omission.
A couple months ago I put a question regarding even using a bonding jumper to a former electrician who was inspecting a project I was working on. It was an uphill effort to convince him that a GEC to building steel, and then a bonding jumper from building steel to water pipe was an acceptable installation. I imagine it would be a real chore to convince someone in my area that a splice in the middle of that bonding jumper would be ok.
Pretty clear in that continuous conductor or irreversible splicing is not required. So do you want to interpret that as an intent to promote undoable splicing? I think not. I'm fairly certain you will agree there is a major difference between permitting splicing and promoting splicing. So in my mind, intent lies closer to minimal permission and far from promoting .Smart, I'll put it this way.

And in less than 2 months in CO the 2011 NEC will be implemented and that opnion will be even stronger with the addition of 250.68(C). As I interpret it, bonding jumpers from rod to rod are no longer permitted. Bonding jumpers can only be connected to water pipe and (or?) structural steel electrodes (and a GEC must be connected to each in order to do so ).A couple months ago I put a question regarding even using a bonding jumper to a former electrician who was inspecting a project I was working on.

250.68(C) of the 2011 cycle is a permissive rule and does not mandate anything.
