NO! Do NOT do that.
This is the exact reason why there are posts like this all over the internet. Because folks cave to incompetent or power-mad inspectors.
Inspectors are human just like everyone else and do need a check from time to time. If he "makes it go bad" for you on a future job then...
Where did I say anything about the type of wire???
I was asking how a line-to-neutral fault is any different than a line-to-ground fault. What does your data say?
NO WAY I'd change all them. He is out of his mind and making a power play that he knows will fail. He is relying on the fact that he thinks you know less then him or that you will not question him.
If it was one or two maybe, but 20 or more? No way.
Some will say just do it so he won't mess...
Exactly, because the 200A meter pan is the smallest component. You don't just add up the panels installed.
Just like one 200A panel from a 400A meter pan is also NOT a 400A service.
ABSOLUTELY not. The service is rated for the smallest component. You can do a 400A riser and meter can, but if you only feed one 200A panel with it it's still only a 200A service, albeit with the easy potential for 400A.
Have you ever done a load calculation before?
What I will give you is it all depends on the added loads. A "typical" 3000 sq/ft home will likely not need over 200A. A "high end" one very well could, which is why I wrote it the way I did.
I don't think anyone is even implying he'd be drawing close to 400A.
If the Art.220 calculated load is anywhere near 200A one would be crazy not to go with a 320/400A service. If the calculate load is over 200A a service bigger than 200A is mandatory.
A new home of 3000 sq/ft with a few toys...
A 320/400A residential service is most often two 200A panels. A $1300 upcharge sounds very reasonable to me. To the guy that got 400A instead of 200A for only $500 more, consider yourself VERY lucky.
Not in an attached garage it's not.
Well, "not too long" is a subjective term. In all the time I've known about this stuff, almost 30 years, it was not enough to simply have a single water pipe electrode.
No help IMO.
If installed it would need to be bonded to the main service electrode.
Yes, nothing in the NEC prohibits it.
Up to 45 deg or buried horizontally if rock is hit.
It is required. A water pipe electrode must be supplemented by another form of electrode.
