My house was completely rewired after a fire. Last night we sat out on the deck late and when I went to turn on the deck lighting there was none. The same for the LV lighting in our flower beds. A little investigating today and I found that the supply wire (NM-B) that provided power to the exterior GFI that supplies my deck and LV Xformer had been cut and removed in the basement. Trying to trace the wire I found two other cables that had been cut. One was to another exterior GFI that we use for Christmas lights and I haven't been able to trace the other. The cut ends of the cables were tucked up under the basement insulation. They are not hot. Aside from the issue that I am going to have Monday with my contractor (the electrician replaced my large breaker box with a cheapo and there are no spaces for me to replace the missing circuits), my question is it OK to just cut cables and leave them unlabeled. Is it just a poor workmanship thing or a code violation?

Trying to add a couple of more outlets to my shop. I am attempting to switch from a single gang to a double gang. The note below is as detailed as I can get it. Thank you for any help you can provide. I pulled out the outlet and whereas I’m accustomed to seeing at the most two sets of 14/2 wire in a box, the previous owner had 4 of them, all connected to one single wall outlet. all of the grounds were pigtailed together down to one single ground and screwed into the outlet. He then had all four hot/black wires attached to this outlet...using both screws and not inserts on the back of the outlet. The same goes for the white/neutral wires. After I disconnected the old outlet I realized I was having trouble figuring out how to use all four of these lines to properly connect the double gang box I want to install. ive attached a photo which shows the four sets of wires now separated from the outlet. Each wire is labeled 1.2,3 and 4. After I took this photo I put wire nuts and electrical tape on the end of each of the 12 wires then I checked for current in each wire as described below. wire #1 is the hot wire. When I turned the power back on I checked all four sets of wires and #1 is the only hot. It’s coming from an outlet upstream. wire #2 branches off and goes to a single light switch in the adjacent room. That switch controls a small Recessed light which shines onto my electronics cabinet. wire #3...is my personal favorite that made me want to call the previous owner and ask “why...just why? This wire branches off goes up the wall, through my shop ceiling and into my master bathroom to power one single GFI outlet. wire #4 branches off and goes up the wall, across the shop ceiling and down the opposite wall to a separate double gang box with four outlets. This one causes me the most concern as it appears where this wire touched the insulation, small burn marks were present. so, I’ve said all of that to ask, this... is it safe to have all of that routing through one single outlet? how would I use these existing wires to connect them properly to the double gang/four outlets I want to install? to make my saga even worse, the previous owner left me with ZERO slack in ANY of these cables. I may very well have to splice them all in order to have some slack to play with. would it be possible to connect ALL of these into one junction box and then run power to my outlet from that junction? any assistance you can provide would be most welcomed and greatly appreciated.
