Fine, fine. Then I don’t want to hear any bitching by code inspectors or anybody else about how I have my backup off-grid power tied to my house. And I sure as shit don’t want to hear any whining along the lines of, “But it’s illegal to disconnect from the grid.”
If you disavow responsibility, so do I.
Do you have it setup to shut off the main when the backup is running? My understanding is that energizing the grid can kill a lineman if power is coming from your house while they’re working.
Yes, you should for reason and probably others.
You can get gadgets to do this for you. Or you can just remember to shut off your main breaker before starting your generator or flipping your giant Frankenstein style knife switch to your battery bank or whatever, and turn it back on only after you’ve disconnected your backup.
remember
LoL, no. What lineman or electrician would want to bet their lives on you happening to remember? If there’s any code enforcement, that’s a resounding no
The correct answer, of course, is a transfer switch that physically decouples the backup power and the grid power from the building, and does not allow them to be connected at the same time – no matter how the operator might manage to fuck it up.
