GeneSF,
over the years i have only ever had the power compnay disconnect a supply not for code violations (as our IEE regs are just a recommendation as to install and are not law),
one property was a largish motor garage that i was called to, it was raining and the rain was pouring into the main panel board (300Amp three phase) and onto the service cutouts and merter area, now that was scary.
i called the local POCO and explained what was happening and they actually authorised me to disconnect the supply.

the owner was not very happy!!!

he had called me in because he heard a crackling sound coming from some very old half inch conduit in the corner of the spray booth!!!
when i investigated that, the conduit was rusted out and the cabling was son damaged that the condubtors were arcing between the tube and themselves,

after the supply was disconnected we got to re wire the whole place, it took four of us about three weeks to fully re wire the building (approx 16,000 sq feet.

the other one was another motor garage that only had a single phase supply but the `man` who owned it was a bit of a DIy fanatic who thought that you could run a 5 hourse power direct on line three phase compressor off of a single phase supply!!

we were called in by a shop next door because he could smell burning just outside of his door, in my years as an elelctrical engineer it never ceases to amaze me how stupid people are with electrical energy.

i just wish our country would adopt the IEE rules as law and convict those out there who mess with things that they dont understand.
