I am wiring an addition to a church. I am upgrading the service from 200A to 800A single phase. The service will be a 800A ML panelboard with (3)225A CB feeding (3)225A 42 ct panels. This church is out in the boondocks and has no natural gas or sewer service, just a septic system and a water well. The well casing is PVC and the water line coming into the building is 1" plastic. It stubs up in the slab in the old mechanical room and pipes into the pressure tank. PVC runs up from the pressure tank for 3' then "T"s off in copper to hit the water heater. Copper comes out of the WH for 3' then goes back to PVC. All of the cold water is PVC until it gets to toilets, urinals and sinks. The POCO wants a 1/0 ran to the water piping. Am I really required to run a 1/0 to the 3' of copper pipe?

Re: Bonding the Water Line?
I think that is ridiculus. The POCO may mandate required grounding however in no case can they tell you what equipment or systems must be bonded to the service. Drive two ground rods and tell them to mind their own buisness.

Re: Bonding the Water Line?
Just out of curiosity, why does this church require such a large service? Is it a mega-church?

That is one of the stupidest things I have ever heard. I agree with Bryan. Drive two rods (or one less than 25 ohms) and go home.

Re: Bonding the Water Line?
Amptech Does the POCO know that the water piping is mostly PVC? I don't think they can demand this.
Call you state AHJ he'll set them clear. PM me with where you are at and I'll try to send you the contact number.

You should also ask the POCO if they want you to bond that plastic line from the well with a piece of 1/4" polyethylene tubing within 5' of where it enters the building.

Re: Bonding the Water Line?
The service is being up-sized to accomodate an additional 24 tons of A/C and 60,000w of lighting. A 600A service would have been adequate but the cost difference between a 600A ML panelboard and a 800A ML was less than $200.00 and the possibility of adding on a fellowship hall in the future is very real. This way, if they do add on, they can just slap another 200A breaker in the panelboard and build away.
