text: Buy cheap night lights in bulk (less than $2 each), plug one into each outlet & turn them on, then all you have to do is turn off one circuit breaker at a time and walk around the house writing down what lights are off for that corresponding circuit breaker.
  Night lights is a great idea. I find strings of cheap christmas lights useful, in different colors even. I can stretch them to where I can see them with less running around than if I had to go all the way to each receptacle or room. For exterior receptacles I route them in front of a window so I can see from inside. Funny, I usually turn everything off, then flip circuits on one at a time (instead of other way around)... am I missing something?
  That way the house loses power to everything, and for a longer time, rather than an average of only half of things for a shorter time each. – mgkrebbs Feb 26 '17 at 21:39
  I have a better solution if your by yourself than running around or running extension cords. Although it may not be feasible for everyone, I had used my security camera that’s powered by batteries so I was able to move it around the house and would turn the lights on in a particular room along with lamps and other devices plugged into the outlets. Then watching the camera on my phone, I’d flip through the breakers to find out which ones correlated with that particular room and jot it down. Another solution, if no camera is available, if you have a iPad there is an app that can be downloaded to be able to use your iPad as a security camera/baby monitor and view it through your phone. Although these options may not be the most “ideal” it has saved me a ton of time vs going up and down several flights of stairs to just check to see if it was the correct breaker I needed.
