    I think the old school method was to plug in a stereo and turn the volume up. When you couldn’t hear it then you got the right breaker.

      I hook a cheap webcam up to a USB battery pack and load it up on my phone. Then I plug in a light and point the camera at that. It makes it a single trip and doesn’t bother the neighbors.
