Read somewhere that THEY are supposed to get a permit, and comply with the NEC is addition to the NESC.
Can't say I saw a permit posted by them...also can't say that they don't comply.
We had an issue with site lighting a while ago.
I know for a fact that THEY do get permits for replacement of furnaces and water heaters. (GAS COMPANIES)
Around here the 'lectric utility (PSE&G) is into "appliance repairs".
