    In this state, the utility companies responsibility ends at the meter,

    local inspector's begins at the other side of the meter.

    I have had standby power since 1984?

    Never had any inspection other than when upgrading to three phase, I did all the wiring.

    An electrician friend pulled the permit, and the inspector, another friend signed off on it.

    All the wiring was done in EMT, a bitch to do alone working overhead on a 16 foot ceiling.

    My system cuts off incoming service by dropping the mag contactors and going to

    alternate system, has to be manually reset, it is an either/or.

    Neon indicators show if outside power is up and how many legs,

    they are in line before the main breaker.

    The system with the mag contactors is not really for SHTF, but to protect

    very expensive motors in CNC machines, and compressor.

    Backfeeding gennies is a safety issue as well a code violations if there's no transfer switch. Damned straight they're gonna investigate.

    Which is the AHJ as well as their own supervisor.

    If they find a running genny and they're out working on the lines, that's obvious and potentially dangerous.

    All they gotta do is ask the homeowner for permission to investigate. Simple as that. Once permission is given, they cannot be sued for trespassing.

    What they (the line crew) usually do is cut the feed to a suspected backfed line and move on to where a repair is needed. Someone else comes along and does the legwork.

    Direct from my local utility's Service Manual:

    Keep calm and try setting SCE to AUX.

    natural disaster SHTFs are one thing - you'll only have trouble with the regular crooks out to make eazy scores .... running your generator in a serious SHTF with long term implications - a whole different set of plays get put into the game .... you'll be ringing the dinner bell by running a generator - any generator - a few weeks into SHTF .... if nothing else you'll be signaling the possession of priceless fuel ....
    Priceless fuel would be heating oil. Every other house has a 275gal tank around here that would be useless to the owner.

    Quick question. I'm thinking of powering a 110 volt sub panel in my house from a generator during emergency power outages. I know about interlocks, backfeeding, etc. But in my panels the ground busses are common with the neutral busses. Wouldn't it be possible for the generator to backfeed to the main panel thru the ground wire and therefore back to the main grid via my neutral to the pole?

    No, it is a ground aka neutral return, your case as in mine they go to the nearest earth ground, and no further.

    There is nothing flowing through the line without a load to bridge it,

    then it goes right to ground, the emf takes the path of least resistance to the first mechanical/ electrical ground.
