It's really disappointing when good materials fall into the hands of people who don't know what to do with it. I can't even guess why this guy removed so many of the tabs in that switch box. I see one or two spots where the romex has been gouged by something. It also looks like he used about three times as much wire as necessary to accomplish this task...(i.e. You can drive from Houston to San Antonio by going through Dallas, but there are better ways...
). I would be willing to bet that any one of y'all could pull most of this stuff out, replace the boxes (with ones that still have the KO's/romex tabs in place) and re-do this job, and still have quite a bit of wire left over.
I have several of the Wiring 1,2,3, books in my library (mostly for grins), and even these books don't advocate doing something this sloppy. I guess reading the book is one thing, and interpreting it is another.
I wonder how many times he twisted those EGC's together
?
