There is a concern on an existing installation where the meter and outdoor load center are approximately 7 feet from the inside wall of an in ground pool. Looking thru 680 I see no violation, not even a requirement to include it in the equipotential bonding as it is not within 5 feet of the inside wall. Am I correct?

I think you are right but look up. Where is the service drop?

The service conductors are piped across the roof for 25 feet then there is a 90 up with a weatherhead. Adjacent to this weatherhead there is a service mast fastened to the building to support the overhead, keeping it 25' from the water. It is not pretty.

It sounds legal tho... sometimes the law ain't pretty wink

Was any consideration given to raceways on a roof? (derating)

I doubt it since my area just started enforcing derating for ambient last year, and this installation is at least 30 years old. This brings up something I have been wondering about, when de-rating residential service conductors would you start with the ampacities listed in table 310.15(B)(6)?

That is why I was curious.
310.15(B)(2)(c) refers you to 310.16
I am not sure what you do with (B)(6) service feeders. I was wondering what size they ended up with.
