WOW!
We wouldn't get away with using 2/0 for 200 amp service here!

Why not, it's perfectly legal for a residential service if you are installing per the NEC.

3/0 no derating allowed here by PNM on Service entrance connectors.

They may have their own rules but, applying 310.16(B)(6) is not derating a conductors ampacity so to speak.

310.15(B)(6)
(6) 120/240-Volt, 3-Wire, Single-Phase Dwelling Services and Feeders For individual dwelling units of one family, two-family, and multifamily dwellings, conductors, as listed in Table 310.15(B)(6), shall be permitted as 120/240-volt, 3-wire, single-phase service-entrance conductors,

This is a stand alone article section that allows the ampacity of the conductors in a specific application and as listed in Table 310.15(B)(6).

I was careful. I feel the worst that could have happened would be to scare the crap out of me and kick some big fuses somewhere and put out a few neighbors.

Are you sure about the worst that could happen?
Around here the utility doesn't fuse the secondary of their transformers.
They expect to clear any fault on the load end by letting the service cable burn itself in two.

I'm in Delaware and i specialize in service upgrades.I do on average of 2 to 3 per day,3 to 4 if all local,i have one man that works for me and we are both on the job and we are really fast and each job ranges from $1300.00 to $2000.00 depending on distance traveled.Most of my jobs require a disconnect with meter so it also depends on how much 4/0 SER is used.We all know how fun that is to buy everyday.

Heh heh ...I have upgraded probaby 100 services over the years and always used 3/0 cu from the standard table until the last 6 or so.

I learned about 310.15(B)(6) on the internets ;)

I did not think Delaware was that big I could wire the whole state in a month.

A lot depends on the area your'e in and what the market can stand. I have done several overhead installations. Charging from $1,500.00 to $1,950.00 Some involve more work beyond the basic componets. Watch how many circuits you have to tie in the new panel with or additions.

Wouldn't it be more efficient to buy a longer length or a reel to avoid the same situation everyday?

that sounds like blood money...i can't fathom doing more than 2 service changes in 1 day...and doing 2 would be a long day...average service change around here is overhead with minimum 20 ckts...heck it takes an hour or more just to label the panels...

what kind of services are you doing to average 2-3 a day?

when you consider removing the old loadcenter, marking everytjing, installing the two ground rods, the riser, and meter pan time can vary depending on home construction, then there is the EGC that may have to run the length of the house, as you said just marking takes time, might be they don't get permits. I would like to know what kind of service they are doing, these magic jobs, or they may consider changing the panel only is a service change. remember DE has limited electricians licenses.
