When I absolutely cannot risk tripping the wrong breaker, or electrical noise makes the tone units useless, I get one of those old-style 'buttons' that people used to put in light sockets to make the Christmas lights blink. I then use my clamp-on amp meter to look for the circuit whose draw is regularly fluctuating by half an amp (60W bulb).

Bingo, John. I was surprised to get this far in the thread to see this idea. I do this as well. Accurate and cheap. If you can't find the "button" john mentioned, it's easy to make something similar on your own by using timers to make your own "flip flop" circuit to control a lamp.
