We just moved into a new house. I've done a bit of electrical work
and no matter how well labeled the electrical panel is, sometimes
it's hard to find the right breaker to turn off. Here's my pro tip:
I called my wife's iPhone with FaceTime (you can likely call your
laptop or something), set the phone looking at the light I wanted
to turn off and then went and flipped breakers until the light went
out (always double check, you might only be switching your wireless
router off!).
