Good afternoon
I am wiring a residential building with 4 units. Each of the units will have their own water supply and meter. I have installed the typical 5 gang meter pack (4 plus public)with service disconnects directly next to the meters.
For grounding I have ran a continuous number 2 copper conductor the length of the building and split bolt connected short lengths down to each water line to bond all back to the main service equipment ground lug. I have also driven a supplemental ground rod at the meter enclosure and ran number 4 to the rod as a supplemantal ground.
The Inspector loved it but I would like your opinion.
