Some of these house wiring YouTube videos are lethal. Literally. Just saying :)
@devinplombier , I am sure that they could be. I just was not comfortable with the instructions in the book I bought. I actually watched a few youtubes and the ones I watched basically showed all the same thing. Fortunately I wasn't doing anything very fancy, just adding three new circuits, but I just was not exactly sure what all I had to do at the electrical panel end of the job.
