At least they used wire nuts on all those flying splices
(** runs and ducks as screwdrivers and other pointy objects get thrown in my general direction***).
Ya I will say that has got to be the worst I have seen in a long time.. What a shame too all that expen$ive NM tied in a bow and connected to the panel. Guess the panel cover is going to act as one big cable clamp when its put on
I noticed from the 6'th and last pic, where those tandem 20A breakers are,
Looks like to me BOTH red and black conductors of each 3-wire cable go to the same tandem breaker? I can see a neutral conductor getting a tad hot!
