An existing building has a 480V, 400 A service with 600 KCM service entrance conductors.
The building will get a new addition, and the contractor will run a 300 amp feeder (350 KCM wire) to a new panel in the new addition.
I would like to specify a concrete encased electrode in the new addition. In addition, it the addition will have a new water service.
Question #1: Can the concrete encased electrode just be connected to the new building steel? Or do I have to run a 1/0 wire back to the existing service panel.
Question #2: What size wire do I need to run to the new water service, and for the meter jumper?
I guess I'm mostly confused because the service isn't near the new addition.
Thanks in advance:
Steve
