Has anyone here ever used a an Electronic Circuit Breaker finder? More
specifically a GB instruments CB locator. This is a gizmo where you plug a
small signal generator into a live plug and with a receiver probe you can
find the associated Circuit Breaker at the panel.
Here is the question. How is it possible to get 2 different Circuit breakers
reacting with the same audio and visual ( LED) intensity? Does this mean I
have spaghetti wiring? Or is this common in or around the same wiring areas?
Or an induction effect? Perhaps a related problem here is that I have
wireless house intercoms, they use the house wiring to send signals around.
I can call the first floor from the basement or the first floor to the
second but I can never get a signal from the basement to the second floor?
I guess that we don't need fancy electronic circuits to get mysterious
It means the device isn't perfect, that's all.
I've found that if I remove the cover of the panel, and run the wand over the
wires, instead of the breakers, that the difference in the audible signal
when it's over the right one is unmistakeable.

I've used the cheap ones and the expensive ones and you still get that
crossover to multiple breakers occasionally. Like Doug said you can better
results putting the receiver against the wires in the panel.
Before we had these high tech devices to confuse us a common way to find a
circuit was with a flasher button, pigtail socket, 100 watt light bulb, and
an analog ammeter. Connect the pigtail socket with the flasher button and
bulb inside to the wire or outlet you want to trace. Then go to the inside
of the panel and clamp the amprobe onto each wire until you see the needle
bounce up and down. You can find the neutral this way also.
Had a Commercial electric version of the GB. I thought it was ok, but
wasn't exact. I was hunting all over for a breaker supplying a
circuit, and found that many subpanels set off the device. I'm
looking for a better tool myself.
