Anther Ufer Question

[spikes2020]

I know there are a lot of Ufer questions, and i tried searching but i couldn't find what i was looking for.

In a catalog, I found a piece of 18" #4 rebar (1/2inch) exothermicly connected to 5' pigtail #4 copper. Is this a loop hole that i can tie this into a rebar system with 20' of rebar and everything be cool?

Another question could i use a few of these to tie different panels and or equipment all back the the "grounding electrode" since it's considered one electrode and therefore "one point"?

Just fyi i would also tie the ufer back to the main grounding system of the facility.

Noobie electrical engineer here....

the catalog i found it in page 23

Thanks!

It looks like that is setup up to put in the footings and tie it to the other rebar. Personally I dont see the sense in it as they make ground clamps that are suitable for connecting to rebar in the footings.

The panels in the building don't need to go back to a ufer unless it is the main service panel. I guess you could locate this product near sub panels and tie them together thru the rebar but it is not required

Ah so i dont need to exo weld my equipment grounds to the rebar, a clamp would work fine?

Well, this design is a nitrogen plant with a bunch of condensers that i was going to tie back to the rebar. It would look a lot cleaner than runing a 4/0 or #4 all over the slab tieing them all together. There are a few tanks as well... but in general i was wondering if it was acceptable.
