It can't be used as the grounding electrode unless the connection is made within the first 5' of the water pipe. However the SDS is still required to be bonded to the water pipe in the area of the SDS by 250.102(D)(1).
IF it met all the requirements of the exception in 250.148(C), would it not be permissible to connect beyond the 5 ft.
Try 250.104(D)(1)
That is not for GECs. It would have to meet the exception to 250.68(C)(1) to be used as the connection point beyond 5' from the water pipe's point of entrance into the building.
If you use the original existing building GES, and the customer transformer is remote as in several hundred feet away from the service equipment and GES.
The code clearly requires a connection to the building grounding electrode system. If the building is structural steel, you could connect to the steel locally, otherwise you need a lot of wire.
Only your AHJ knows what that means. Some say it requires a qualified electrical person at all times, and others say it just means that only qualified electricians service the electrical system.
This image pertains to the SBJ, but disregarding that. Is the GES in this setup correct? Being that it has no bonding jumper from building grounding electrode system to transformer grounding electrode system.
That appears to be a transformer that is not in the same building as the feeder to the transformer and in that type of installation, it can have its own grounding electrode system.
Thanks for clearing it up.
The way I read the code rules you have to use the building grounding electrode system where the SDS is in the building. There is no requirement to add additional electrodes for the SDS.
Is your transformer in the same building as your GES?
