Ok, so as a follow up - the licensed genny guy came in and did his stuff. He followed the rules related to the multi branch circuits, etc.
I was doing some testing to make sure all the label are correct and I am having a MINOR issue (I THINK).
I had a multi branch circuit that controlled the furnace fan (furnace is gas) and the living room lights. So he moved both circuits over to the genny panel (each on its own breaker) and tied the shared neutral together. All seems on the up and up....
However...now for the life of me, I can't get the living room lights to shut off (via the breaker). I turn the new genny breaker off for the furnace and that works fine. Then I turn off the circuit for the living room and heck the lights are still one.
Now it gets weird....so I decide to make sure the hot is indeed turning off with the breaker, and it is. YET SOMEHOW the lights are staying on.
I assume I have a PROBLEM somehow with the neutral back feeding, but even if I turn off BOTH CIRCUITS (furnace and living room) I still get the lights to stay on...yet furnace is out. ?? Is there a way to test for this safely? Any other clues ?
Or is everyone as lost as me
