I hate to be nit-picky, but the GRC nipple could be argued to be a violation of 250.6(A) and it appears that 250.92(B) may be violated if the KO's have any eccentric or concentric rings left on the box where the nipple is connected (and assuming there is no bonding bushing in the meterbase that I wouldn't be able to see).
PVC will solve both problems in the future.
That's one that I learned raht-cheer on ECN!
(Thanks Bill)
