I installed a two meter service, one feeds a two pole 40, and the other was an upgrade from 100 to 150. I ran a #4 to the water main and used it for the 150 panel. I reused the #6 for the 40 amp panel. I installed two ground rods, one for each panel, seperate from each other. The boss said I was supposed to bond all the grounds together, by running just the #4 from the 150 to the water main, and bug a #6 from the 40 to it, as well as running both ground rod wires to one ground rod. Is there a code that is specific to this situation. (I live on Long Island, Suffolk County, New York. I don't see anything in LIPA"S redbook.
