This won’t back-feed electricity… so why shouldn’t I ?

My intent is to determine if my thinking is sound.

I never used to lose electricity to the house. Now it happens All The FRICKN Time.
Thank you so much DTE… The regional monopoly on electricity in SE Michigan… Sooo

I’ve got an exterior main electrical disconnect that I want to isolate/shut off (to prevent feed-back) and a sub panel that I want to apply generator power to.
My portable Firman generator only provides 120 V… All I need to power up are lights, 115 V refrigerator and standard household boiler in the winter. But in theory, the entire sub panel would be energized so I could run everything from router, TV, desktop computer, kitchen appliances, yada yada

What could go wrong?

If I had an inverter type generator, I would do the exact same thing and listen to my stereo, as I would feel confident between the inverter, and my PS audio regenerator would provide a quality power supply.

TIA thoughtful thoughts are appreciated

    What's the worst that could happen?
    I disabled signatures.

    AFAIK, Nothing if I disconnect from the grid . . . BY shutting/closing the main breaker

    Your power company wont let you do it that way.
    You need an undefeatable interlock system.

    Who’s stopping me from trying it

    I’m tapping into a sub panel that’s downstream from a main disconnect that’s disabled
    This disabled panel should prevent any potential feedback

    I'm pretty sure that's illegal and if any electrical incident happens, insurance may not cover it. The reason being is that all one has to do is make a mistake and they can kill a linesman repairing a line upstream from the house. I would seriously investigate this further before you do something you regret.

    Pull the main breaker, nothing is going outside.

    Until your wife's brother comes over to borrow something, sees the disconnect, figures he'll help, and.....

    This is what I use. A bit pricey for a little piece of metal, but keeps things legal and safe. Don't be that guy with the suicide cord which plugs into the dryer outlet.

    Yup.
    Cheap insurance.

    Thanks! that's helpful

    I failed to mention that I have an exterior disconnect that would allow for a padlock (or equivalent) to keep the disconnect switch in the OFF position

    The sub panel also has a main disconnect that I'd throw, too.

    anyway, thanks for all the input!

    Yep

    Interlock Kit: Meets NEC Code 702.4 regarding installation and operation of optional standby systems.

    Good 'nuff for me. 👍

    If your gen only supplies 120 you do realize that roughly half the house won't be powered. Unless of course there's either a jumper wire, "suicide cord", double male connection, or another 120 gen to provide power to the other 120 leg.

    FWIW the 120 inverter gens aren't as clean as they advertise them to be. They are quiet though (very neighbor friendly) as they don't run wfo constantly and they only sip gas.

    If you lose power as much as you say I would recommend doing things as correctly as possible. A 240 inverter gen with a properly installed transfer switch would be ideal imo.

    FWIW, here's what ours looks like. It's a little complicated because we have two different photovoltaic systems, too. They're both in a "net metering" configuration.

    Our whole house can run off the generator hookup, which is fine for a permanent installation with auto switchover, but a little cumbersome with a portable generator, since there's no "clue" as to when the power comes back. I have to check the supply meter once in a while to see when the utility power comes back on. It's a minor inconvenience except when the weather outside is really terrible. ;)

    Our daughter's house is wired with one circuit (a light in their entryway) that is always connected to the utility power. When they have a power failure, that one light is their sentry to know when the main power comes back on.

    as a semi-on-topic electrical aside -- I freaking hate GFCI outlets. Just had one go bad (this is the second one since this house has been "on line"). Just a pain in the neck.

    That is all.

    GFCIs suck but AFCIs are the bane of my existence. Our house is new enough that they are required in about 80% of the house and I have had 5 of them go bad in the time that we have lived here.

    At least it's not an AFCI. You can sneeze and trip one of those.

    I don't even know what AFCI's are -- jeepers. This house is less than 12 years old.
