Ok. Here is the deal. I have a 1200amp 3 phase main breaker. 208 with a nuetral. The nuetral will need to be grounded for the 1200 amps at the nuetral terminal in the main disconnect box correct? Now there are 8 200 amp modular meter sockets. 2 meters in each bank. total of 4 banks. each bank has a ground block that is mounted with 2 10/32 screws, paint not scraped. Do I need to run a ground from each block, total of 4, down to the ground rods? 4ga ground for each be fine? Or tell me what you would do! Thanks
 
If your equipment is service rated it will have a bond factory installed see your cut sheet if you cant see it on site. Also notice 250.24(B), sounds like you have one service disconnect therefore you?ll have one bonding jumper, size it according to 250.28(D).

The utility company will most likely furnish and install the meter circuitry.
 
A grounding electrode conductor from the 1200 amp main to your electrodes should suffice.
