Okay im doing a 200 amp service change. (1)Does my ground have go from the panel to the main water line then to my ground rod or can i save some money and start with the ground rod first ? Considering prices are so high for coppper i dont want to back track my ground and use another 50 ft...
I totally agree with je1ff. #6 wire to the ground rods and # 4 to the water pipe with proper clamps to jump the meter. Have never seen it done any other way. Years ago they just ran it to the water meter but not today.

I tend to disagree with the handbook drawing in this instance. The last sentance of 250.53(D)(2) states that a supplemental electrode must be bonded to: 1) The GEC, 2) The service nuetral, 3) The service conduit, or 4) A grounded service enclosure.
One of the electrodes in the handbook drawing MUST be called a supplement, and bonding the supplemntal electrode to the water pipe is not one of the 4 options listed above, as per 250.53(D)(2).
