In years past I have done many homes with 2/0 cu for 200 amps. I see no reason to use 3/0 unless that is what you have on hand.

Another EC I know intends on doing this...I can't figure for the life of me WHY?

It will make him feel warm and fuzzy inside.
Me ......... I would feel like I just through money down the drain.

The "idea" is part of an overall service upgrade "package" including Eaton's PLUG-ON NEUTRAL LOADCENTERS:

The price being sought would certainly give him a warm and fuzzy feeling all the way to the bank.

Good, Better, Best. Why not step it up to 4/0?????, it's only money.
That's my thought too....whatever is the largest conductor the meter pan can handle.
...but why?
I don't understand.:-?
It just depends on the situation, for some old lady or the nerdy dude in the city, then of course 2/0, but for the redneck guy like me, out in the sticks, then 3/0, which when I build my house it will have a 400 amp service on it. What I'm saying is it depends on the situation, it the person plans on adding a detached garage or barn then I would go with 3/0. If you know nothing of any size is going to be added then the latter. Houses are a lot bigger now than in the past, it doesn't take long for things to add up. Just my 2 cents.
It's typical SFH...nothing extreme...
What if that is only what is being offered [and it is]?
No amendments..no "time is of the essence".....typical straight-forward 200A OH SFH upgrade.

I wonder how many screws the neutral clip covers?

200a gets 2/0 based on resi code minimums. h/o's want to add stuff in the future and i might add that stuff. I say lets go with 3/0 cause they will hate me when i say your new sub panel for the addition is gonna require yet another service upgrade.
Probably...all of them :grin:
Considering that all ckts are now essentially GFCI or AFCI ~ who cares...the ckt's neutral goes right to the CB...the clip on the CB is making contact with the neutral bar.
I could be wrong on the configuration..I haven't RTFM :smile:

What do think the average load is on a typical SFH?
What is the peak load on an average house, ei. thanksgivings day, etc.
To answer your question, no more than 40a IMO.

Question is, does your poco provide a large enough service drop conductor so that your 3/0 makes any difference.

The size of the pocos drop doesnt really matter its not in pipe.
Sometimes you are working for a smartypants engineer who not only knows everything there is to now about electrical work but also bird dogs you the whole time and insists you use the wire size he "spec'ed" out regardless of what the code says, and by god he knows too and that's why he as a 400A service on his shed out back.
