can it be used to test romex home wiring for insulation value phase to phase and to ground

It will test any insulation breakdown but, as others have said, is designed for motors. It will give you a range but you will have to interpret what it is telling you. The range values on the meter itself is based on a 240 volt motor. For testing home wire insulation its best to use a true "megger".

You're better off dropping some real money down for a digital megger for the application you would be using it for. This little guy is really only meant to tell you if a motor is dead or on it's way out.

Sure, why not? That is what a megger is for. I have this one and it works great.. (BTW, I think you mean L1 to L2. Not "phase to phase". Not many residential homes have multiphase wiring. In any case, it could also do multiphase (3) testing. (2 Phase is no longer used, since it is very inefficient wiring wise.)

Hi, thank you for contacting us. I'm afraid the tester can only perform test when component is NOT in circuit. With best regards, Kevin

I don't see why you couldn't do that. The controller reads the probe as a value of resistance so it would really depend on the cable and wire you use. I've only used this with about a 3ft (1M) cable length. I guess you could run the wire, then test and calibrate the settings/readings on the controller, that should work. I haven't had any issues with mine. But again, I'm not using long cable runs either... Hope this helps.

This type of tool can sense a hot circuit through both the individual leads's insulation and the sheath insulation. However, I don't know if this particular product will reliably do so. I have had to spend more time and effort than I would like getting a result that I was certain I could trust. Please note Trina Buchanan's response, too; she has the credentials. A different model or brand might be better for you.

Yes... as long as it is a 3-prong outlet, it will test for polarity and proper grounding. The only part of this that is for the GFCI plugs is the push button which drains off a little current. If you push the button on non-GFCI plugs (or non-functioning GFCI plugs), nothing will happen. BTW, this is one of the best testers like this that I've found.

I have only used it on 18 to 22 gauge wire. I found a piece of romex in my shop. It is not heated and about d degrees f right now. It did not work very well I did not think. I gave it a few tries. some attempts were better than others but did not have good consistent result. Hope this helps.

It's designed for tracing wire . If one side is grounded trace the otherside. For your purposes turn breaker off disconnect wires at both ends, measure the short with a volt ohm metercut ohms in half and multiply by 12 or 14. With a 12 ohm loop divided by 2 is six ohm s times as equals 72 feet. This changes with the gauge of wire. Then trace with one lead frthe toner to earth ground the other to the wire. Or, you could buy a ground fault meter. This is the best I can come up with for these tools.

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.

It can be used to test this if you have access to both the fence wire and the grounding source.

I have only used this tool for automotive wiring. So I can not say how it works on romex.

Yes. The instrument has two detection levels, one for low voltage and one for house voltage and above. If you want to check for wires behind walls, switch the instrument to low voltage detection mode. It will then me sensitive enough to detect house voltage in lines behind walls. I've used it to detect wires behind lath and plaster walls which are generally over an inch thick. In high voltage detection mode you have to have the end of the instrument very close to the line, almost touching it, for detection.

yes it would work for that, but youd want to be able to access the individual conductors to get a clear tone from the probe, if the wires are all inside insulation it will give you a reading but it might take a few goes to be 100% sure.

No, you can test through a patch panel, but a switch is looking for packet info and isn't a straight through path on the cables.

Since you are testing continuity of a single run, if one end is in one room that's where you plug in one of these. Then you go to the location where the cable terminates and plug the other part. So yes if it's the same run you can test it that way.

Yes, but I would only use these wires for testing. These wires are too thin for everyday use.

I think so. I used it in AC wiring mode on concrete walls covered with plaster.

yes however the wire polarity may be switched so test before putting everything back together.
