Would this detect a live wire behind lath-and-plaster? I'd like to detect any energized knob-and-tube wiring in an old house. Thanks!

It has sensitivity adjustment and though I have not tried lath I can turn the sensitivity up and hold it 1ft away from a live wire and it will beep.

No it won't. It doesn't have that ability. It has to make contact with a wire.

I don't know that it would detect behind lath and plaster, especially with knob and tiube wiring. I had no problem following live romex behind drywall, the adjustable sensitivity works well for this, but the extra depth of the lath and plaster might be a problem.

hmmm. i didn't realize it was for ghost hungint???? i use it to measure emf emissions and i love it. you move it around the appliance and it will show the emf emissions. i had one that was a lot more expensive and technical showing exact measurement but it was awkward and difficult to use imo. i like this one because it's simple and gives me te info i need. you point and push the on button and get the reading. i love it. !

I did, and had no problems with the wire, actually I bought a heavier wire as the lighter wire broke and tangled easier than the heavy guage. A steel alloy rod, purchased from Home Hardware, used for grounding house wiring, did the trick. Make sure its in damp ground, where you install the grounding rod, I would run the hose around my ground rod now and again, just to make sure.

No, if you watch one of the Utube videos, it shows that wrapping the wire around itself doesn't really work. I would watch the video if you are installing a new system.

That depends on the regulations in your area. Maybe ask your local building inspector. My experience was that the connector for the Kidde smoke detector that was already there did not work well with this unit. There were false alarms. It worked well after the correct connector was wired in, but it does not trigger the other Kidde detectors in the house.

You might have... I'm certainly not a professional electrician, but mine works fine on both GFCI and regular outlets. If it's not something with your wiring, it's probably the tester!

Hello, I have no idea, was just curious about the item and thought I could use it to possibly track down a wall switch that goes nowhere in our house. turn off all breakers but the circuit the switch is on and check for a signal thru the wall with the switch on and follow it, have not tried yet. Just checked around a few wires and it does sense the electricity. I think the deal on it detecting cameras is that you can see the infrared with it or something. Have not had time to really check, it may just be a barely useful gimmick. But I hope I can trace the wire. It may make a cool kinda selective sensitivity signal tracer.Peace!

A connecting wire would need to be run between the two. It would be a choice of above or below the window. It could be run through the attic too. Since it's low voltage, there might be a power loss if it's too long. A good electrician could fish the wire through the cabinets and wall.

My experience is that the sensor must be very close to the transmitted signal. My opinion is it would not work for cable behind wallboard, etc. Could be a help in sorting out cables you can touch.

Bare? No. If left unspliced, in conduit, yes. Check your local electrical codes.

That is a tough question to answer...If they are turning themselves on because you are getting a spurious signal through your building wiring then the answer is "MAYBE". You wouldn't know until you tried it. I suppose you could buy one and if it didn't work you could return it for a refund. That's about the best answer anybody is going to be able to give you...

I think so. Basically you are just plugging in a wire on one end and running it down to the other. How you hide it in between will show your experience and luck :-)

I am not sure. I am not good with that kind of stuff. there only are two wires connecting the two. I can tell a difference in my house. we live in Hot Arizona.

Green wire, in a 2 wire home, generally can be attached to the ground wire. Be advised that I'm not familiar with your house, so you should contact a licensed electrician to get a hands on look at your wiring. I am only telling you of my experience in your situation. Do not assume that you will have the same result that I have had, or others that are answering your question. Be safe............

I really don't think so. I'm not sure that the sensor can read the signal through a wall along the path of the wire as it does at the breaker. Admittedly I've never tried to.

Not particularly. And a bit of advice..have someone install it or look at it. It may need rewired. Mine did. The transformer was faultily wired and burnt up the ground wire in the light. Thankfully my ceiling tile isnt wood.

While I'm certain the professional and safest answer is "get your home rewired", my home is 90+ years old and only two conductor(no neutral) and its worked for us for years now. Good luck!
