Installing and connecting an outside generator power inlet box
I ignored the main power box as a typical portable can only produce a small fraction of the main supply. I put a receptical box inside near where the generator will be outside the house, conduit through the wall and out to the generator. The refrigerator is fortunately near . Then I use temporary extension cords as needed ; a bit of a hassle but but not bad for a couple days a year. I have used it a few times and it was satisfactory ( 2,000 watt portable). I supply a room AC, TV and some lights, phone and PC.
