I am in the process of removing a wall from my home separating the kitchen and dining room. To do this, I needed to remove the wiring from the wall. Steps I took: Shut breakers off to kitchen lights, kitchen outlets, and dining room outlet on same wall. This was 3 breakers total, shutting off power to half the house including some rooms and the garage. I then removed wiring from all outlets and light switches, so that I could remove wall studs. After removing studs, I capped all wires with wire nuts, stripping them back, etc. 3 wire nuts for each electrical cable. I then flipped all 3 breakers back on to get some light in the other areas of the house, and no power. I used my non-contact voltage tester and none of the outlets attached to the other breakers are functioning. Only 2 of the 6 cables I capped off have any current with breakers on as well. Garage has no power, etc. Only devices not on one of those 3 breakers have power. I do have an electrician coming out next week to move a couple light switches as they will need rewired, but can someone give me some ideas as to how I can get the power to the rest of my house back? There are no GFCI outlets in the kitchen. Bathroom has a GFCI outlet, which I have tried resetting, but still no power.

I'm making an outdoor kitchen with an electric smoker (1200W) and a mini fridge. They will be 110 ft from the breaker box. Should they be on each their dedicated outlet/breaker? What wire sizes would I need? Thanks
