Umm yeah Dale that is what people use. It can be used on romex or phone wires

 

When you use that particular device you MUST have the power off. I have used them to find open circuits which turned out to be in buried junction box.

 

The reason why you was probably getting a weak signal is if the wires did have voltage going through them. Make sure it is disconnect on both ends

 

wire tracing

DaleB I carry 2 little inexpencive tester. One looks like a fat ink pen, it has a plastic tip and when it gets close to live current the end blinks red and it makes a beeping sound. This one is handy to trace wires from a switch or receptical. It comes in real handy to use before I cut a hole in a wall.

The other one has 2 parts, one plugs into a receptical and the other you bring to the braker box and slide it down the face of all the brakers untill it beeps. It will tell you which braker is connected the the receptical the other half is pluged into. Then you can turn that braker off to make repairs with out turning off the wrong brakers.

 

Tracing elecrtical wires

I'm curious why the power needs to be off? I thought that it fed off of the current in the wires to trace them. Apparently, the power to trace the wire comes from the transmitter itself? Also, regarding the other two testers I have both and they help alot. Thanks.

Yes on the other type mentioned above needs the power off. It sends out a low voltage ping that can be picked up by the receiver.

 

They work well. Exactly how well I will tell you tomorrow. I will be using the probe and tone generator to locate buried junctions boxes in the walls. I'm going to enjoy busting open those walls to expose the junction boxes!!! Why do people think it is ok to bury junction boxes!????!?

For DIY there are two ways to trace AC wiring, with Power OFF & with Power On.
1) For bigger bucks there is a third choice Pwr OFF or ON e.g. The Greenlee 2011.
On this puppy the receiver will operate up to a 4 miles from the transmitter.

2) The Power Off tracers are the phone type tracers. I use this tone generator/kit:
Test-Um KP100 Field Kit: TT100 & TG100 in a Cordura pouch Test-Um KP100, KP-100, KP 100
It works fine for shorter runs. The main problem is that due to the small transmitting power of the generator anything that is plugged into a receptacle will suck up the signal. Another signal killer are lights that are not turned Off.

3) The Power ON tracers center on the Circuit Breaker Finders. These I think s/b just called circuit tracers because while the circuit breaker function is valuable, they are good at tracing wires in a wall or to sort AC wires in a bundle. Here is a higher end tracer that is advertised to trace cables to a depth of 15". Try that with your phone tracer.
ECB50A - at the Test Equipment Depot

Wire Sniffers as has been pointed out are also useful.
HF Non-Contact Voltage Tester

The sniffer that I like is the Greenlee GT-16
It has an adjustable threshhold so it can be used to trace doorbell wires, Thermostats, LV Yard Lighting, or even those Xmas lights
Greenlee GT-16 - Non-Contact Adjustable Voltage Detector, AC 5-1000V

I know this is an old thread but the above device seems to be still available. I need to trace the source of power to this:

Sorry, the picture is on it's side but the previous owner put outlets on the stairs. I have found some lights that fit into a single gang box. These outlets are not switched, as far as I can tell. This device should work to locate the line in the crawlspace and wall? Will it help me determine if it feeds power somewhere else?

Thanks!

 

Will the tracers work for wires in conduit? Specifically the ECB50A? I'm trying to figure out how the conduit is run through the walls.

No. But this should help:

wtf is with those outlets on the stairs?

 

I don't think they are receptacles. They are probably lights.

 

Guess the previous owner had a short cord on their vacuum cleaner. :laughing:

Interesting idea, but I would have at least centered them, or put one on both sides, so it's more, symmetrical. :laughing:

 

When the GC quit in the middle of building our house, on his way out he ripped the sheaths off of all the roughed-in circuits at the panel (no breakers installed yet). I had about 40 circuits that I needed to identify. One technique that I used was to connect a 1K resistor across the hot and neutral of a circuit that I wanted to identify, then scan them all at the panel with an ohmmeter.

 

I don't think they are receptacles. They are probably lights.

No those are receptacles. Only other option is to remove riser and put in another. Since it's a bizarre conversation piece will add a switch if I can.
