if the code doesn't care, why should I?

Generally speaking, documents never care... but on this and several other related matters, I care. Most inspectors care to some degree. To what degree you care is up to you.

That said, the way I see it when in a section regarding the grounding electrode system, any mentioned jumper is a grounding electrode jumper. Not an equipment bonding jumper or any other type of bonding jumper. I believe it makes a difference.

the point would be that it does not appear that the same rules apply to bonding jumpers between GE as apply to an actual GEC, so why would I care what rules apply to a GEC when looking at a GE bonding jumper?

Question on bonding to structural steel, Is it ok to use the thinner wall girder, the ones that the siding gets screwed to ?Also are the bolts that attach them to the major trusses Ok or should we bond at that steel junction as well.

Code isn't that specific. Tradespeople must use their professional judgment coupled with the requirements of 250.4.

Because many (or at least a few :D) are one and the same.

when would a GE bonding jumper ever be a GEC?

Not saying they will ever be the same. Pretty obvious they will never be the same... so quit jerking my chain. :rant::D

I'm saying there are requirements which apply to both equally... and there are also sections in Part III which are specific the bonding jumpers (used in the grounding electrode system).

The inspectors in Carrboro NC made me change a 1/2" UL Listed 8ft grd, rod. To a 5/8ths , They made me look bad to my customers.

I believe that was awhile ago because Rick didn't realize it was listed. I believe if you showed proof of the listing he would be cool with it. Buy your Rods from Hunt or City and you won't deal with that Lowes stuff...LOL
 
Is it in the NEC about the min size ground/bonding wires for the different Com company's, Smart$ mention #10 for broadband coax.

That #10 was from memory. Apparently, my memory isn't what it used to be. It appears the requirement is not smaller than 14AWG, not greater than 6AWG. I believe all Chapter 8 articles state the current-carrying capacity must be at least that of the communication cable's grounded member(s) and protected conductor(s). No greater specificity is offered.

The code doesn't actually say that. It just requires the connection be made there.

You may be right that it doesn't actually say that. But it sort of makes it appear as though that is what they intend.

Before the 5 foot rule from entry to GEC attachment point came into play, you could attach the GEC to any point on the water piping, you could attach bonding jumpers to other electrodes at any point on the water piping. Now both must attach within 5 feet of the water pipe entry, which effectively makes that first 5 feet part a of the electrode but anything past 5 feet is not a part of the electrode. Building steel - not the same at all, you can attach a GEC or bonding jumper anywhere on the steel, accessibility of the connection is the only thing that may be an issue, but also is with the water pipe.

I have never looked it up, but if I recall correctly, structural steel would be exactly that. Red iron. Purlins are not structural, per se, mostly just to attach siding, the siding itself provides the shear support.

Take the purlins out from under roof steel and throw three feet of snow on the roof and then try to tell me those purlins don't provide any structural support:D

Smarta$$ off all you want, structural steel is red iron! Think he's gonna pull GES to the roof? I don't know why I keep coming back to this forum:rant::rant::rant:

I agree with you for what is typically called a purlin. However, the question I replied to used the term "thinner wall girder". I do not know his "thinner wall girder" was, in fact, a purlin. My reply reflected facts not in evidence.

I guess Im still a little confused, If the 2/O that is connected to the incoming water pipe within the first five feet, is there. And it runs to my main distribution panel.Can I bond 10 or 15 feet away from the water pipe connection.I just was planning on using a Burndy split bolt to the bonding wire coming from the CATV Box.I was looking at 830.100(B)(2)
