Quick home electric question

The problem with your last plan is there may not be a lockout made that will fit that configuration You will simply have to do some research. if not, you could install a big transfer switch 'ahead' of the last box. It's for sure a gymnastics act between affordability, convenience, and legality and safety

Also consider the safety of the generator.........lots of thieves make off with gensets, and all they have to do is listen and watch. If you can afford some wire, you can move it
the last picture i posted, is a lock out made by eaton for the CH style panel i have, so that base is covered
if plan A or B turn out to be impossible, ill look into the transfer switch

A "quick" question, or 50 lmao.
Be a man call an electrician. Some of the home "****" you do is ridiculous. We can only hope that you only take yourself out.

other then you guys, ive actually talked to several people
but id like to get an idea of whats going on before i pry open my wallet and have someone come out and do what i might be able to do on my own
(im actually waiting on the city electrical inspector to get back to me, he should be able to put this whole thing to bed)
