90.4

when I was little I had to rip out a supplemental ground rod at a remote loadcenter that was just bonded to the ground bus only.
what's wrong with that? "parallel paths for the ground fault current" ... meh
but isn't another rod required at xfmr, outbuildings and hot tubs?
and who cares about a rod anyway - its the water that counts

I thought it was unreasonable and read soares cover to cover
abandoned the supplemental ground anyways
I had driven it by hand!

Right but in my case I am the AHJ and plans reviewer. If its gives equivalent safety no harm done then why not allow it? Lots of things are not in NEC or gray area
 
easy , you take responsibility and sign 90.4
what's the prob if you are ahj?
anyways, none of my business, this is why I got off twitter...

I got to get something done !

"you can spend the whole day looking for that hour you lost in the morning "
 
well why didnt the guy build what was approved?
too bad.

he could at least ask "what are you drinking"

I get it, you are looking for a work around.

the only problem is that there is only one place in a code compliant installation where the center point of the tx touches the cold water and that is the meter disco
 
like in my problem, there is at least a plausible pathway to view this as a plausible reason, even tho it really looks like it missed layout
and the people are kind of on fixed income, hardship etc

2442 or 612126?

https://wr1.live/2442-or-612126 Old client calls me, can I bring a new SA circuit from the main to the adjoining area to the kitchen. Its a condo conversion for her parents. There is a narrow counter there and it looks like it is missing layout. I go there and find a fairly good looking...
forums.mikeholt.com

I don't see the workaround for the bond being downstream.
move it upstream and isolate it down there

let him drive another rod at the fused disco.
they have 25# electric hammers now!

and pull to the cold water or whatever

what's the problem
where's the hardship - I didnt get that part.

just run a #2or4 to the service grounding electrode system.
abandon the n-g bond downstream done

what's the issue

As an AHJ you approve an "alternate" to the Code and something does go wrong you may end up in court trying to defend youir decision aginat a someone with a whole page of credentials and a vastly better knowledge of the Code and electical theory. Yep! I think thats a great plan.
I would love to watch the show :)

augie that is also alarmist.
I worked in the German embassy and their facilities guy told me
"you Americans think the electrical system is a vault filled with money, most of these things are unnecessary"
and he was an electrical engineer

Why do you come here asking questions, then argue with the replies you get? If you have to ask, it's obvious you don't know, so why argue when given the correct answers?

So the correct answer in this case is yea it would work fine but its not what code says? So just make em do it per code.

You all didn’t think I tried that path before I came here. Engineer says its already installed he is not doing it. Inspector almost approved it in field waiting for approve plans.

Thanks for all your help and input. I really appreciate.

No more arguments or replies from me

Thats what a written permission is. Its in NEC??

It's clear what is required by the NEC. Why would you want to put your name on an installation that is not code compliant? Tell the contractor to install it per the NEC and that's it. If you're looking for confirmation from this forum for to approve a non-compliant installation I doubt that you'll get it.

I would strongly suggest that any AHJ have a discussion with the attorney that would have to defend your choice to use 90.4 before you actually do that. Our city attorney has flat out said that there will be NO 90.4 permissions issued.
