How to Use a Non-Contact Voltage Tester

[@Mowers11]

You are so right about this claim noncontact voltage tester. I have one in each of my tool bags. I have given them to my nephews when they do electrical work in their own homes. I want to keep them safe. This device is so necessary if you’re doing any electrical work at all.

[@sandywoolf2883]

The video explains very well. The voltage test pen is still necessary. I bought a renhotecic brand test pen not long ago. The test is very convenient, accurate and safe. Family must.

[@flannelguydiy6458]

thanks for watching...

[@charliemartin-k7m]

I need to get one of these for a wire I found near a old shed that feel and the wires are caped but I need to see if any of switches in the house turn it off or if its linked to the main power to the house.

[@johnmckee7937]

These are life safer! I showed my my 70 yr aunt aunt and 30 yr old niece how to use one. Pass on your knowledge!

[@Me04120]

I find these to be super useful when opening up an outlet and trying to figure out where the power is coming from and where it's going to. First kill the power and pull the outlet off the wires, then re-energize the wires and check the lines. The lead line should beep for being hot, and then the load should still be dead. Very useful if you're about to replace an old outlet with a GFCI. Then re-kill the power, and wire in the new receptacle. After that you should be good to go.

[@Big_Country843]

Great video and thanks for sharing. Would this pen work to check for a live wire with higher voltage (240) on something like a hot water heater?

[@omegaman1409]

There are clones out there going for cheap and can make sound and show graphs. I bought one. Definitely a handy tool. Before I was scare of dealing with switches, breakers, and outlets. This sure is a safety measure.

[@chevy4x466]

There is a clone I like, thinking about getting it. How is yours

[@petruse8893]

This tester does not tell you if you have power in the outlet or a switch. It tells you there's voltage on the line,but you can have perfectly good reading ,indicating good line and the outlet does not power anything. Easy test proves the pen is not a tool to detect power in the wire- rub the tip of the pen against any plastic bag. It will glow red and chirp( if the function is present). Needless to say , the wattage shown is minuscule.If the live wire got shorted under the screw in an outlet and there is an oxide/carbon build-up on the wire,the pen will show you a perfectly good outlet,which cannot power anything.But keeping in mind all the limitations, a useful gadget

[@shadowByte99]

thanks for the insight

[@janicechapman4595]

Right

[@JP-xh3gy]

My pen came with an outlet tester. I guess they realized that could be an issue?

[@Windsongwoodshop]

I have this tool. Can't figure out why it can go from green on the right to blue on the left.

[@f0ogz856]

i put the tester up about a meter next to my wall and it started beeping hard. what could be in my walls that extend the range by a couple feet?

[@pattyg982]

This came with my new Dewalt multimeter and I didn’t know what to do with it. I thought it was very cool going around the kitchen touching it to the Keurig wire, the air fryer, etc. But then I touched it to a mixer that was not plugged in and it gave me a positive reading. What’s up with that?

[@Nothingmuch1039]

Thanks a bunch! I have to replace or... Troubleshoot a disposal. Before I do anything I wanted to make sure it was getting power. Like your light bulb example! I appreciate you!

[@pp2devane]

could this be used to detect if there's a wire in the wall? (so you don't drill a hole there?)

[@flannelguydiy6458]

no, for that you need a different device which I also made a video on

[@mbdeuceduece4451]

What do the different colors mean??? There are different lights from different breakers. Doesn't matter if it I turn off the main fuse or not

[@stevemiranda3659]

What about for mechanical use ? Relays all that good stuff

[@edwardwest2795]

I like the one that also has a plug in on the othet side that tells you if its wired correctly.

[@jbobdavis1984]

Will a detector like this register voltage from a dryer outlet?

[@flannelguydiy6458]

it will detect the current but will not tell you the actual number of volts

[@LuisOrtega-dy9lm]

Which is the common setting?

[@casper1995able]

These are nice for tracing wires and checking outlets but if you can check voltage with a meter always do that first.

[@flannelguydiy6458]

yes checking the voltage is something else. This thing can test if the wire is live right through the jacket.

[@Pingaheimer]

This will accurately detect a live wire?

[@flannelguydiy6458]

yes it will

[@Pingaheimer]

[@TheVideoNorm]

Nice explanation & demonstration, thanks!

[@fordummieslikeme7575]

Is there a beep feature on your model? I have the NCVT-1.. It beeps pretty loud repeatedly along with the red light flashing but sometimes only one beep but most of the time continuously and it doesn't stop until you pull away.. Which by the way your link seems to be upgraded from your NCVT-2 to the NCVT-3 Also mine does not have any selection for different voltage but it does say on the side sensitivity ranch 50-1000 V also mine only has a power button which can unfortunately be very easily bumped! And I think I remember receiving a notice from Amazon that my model was recalled lol

[@mitchellmoravec7434]

Such a clear and concise helpful video. Thanks!!

[@leizhang7415]

What is suggest tester for so much wires in a large box if test single wire has power with insulation with so much wire cross each other

[@flannelguydiy6458]

I suggest turning off all of the breakers until ALL of the wires in the box do not have power going through them

[@s2kseth]

You need to be a teacher I love the way you explain your work.. thanks keep it up.

[@tyroneparker4920]

Can test car fuses

[@mrsticker2]

How do I know when to use 12-1000 or 70-1000?

[@flannelguydiy6458]

it should come with instructions

[@leonardbartholomew5021]

Never at work with out it but I have found the one with the flashligt to be very handy. Soon after you start carrying it around it power cycles and beeps in your pocket. I think the battery spring just needs to be more robust. Sometimes a small washer helps for a while.

[@flannelguydiy6458]

Right on

[@brianjackson3031]

What does it mean if my fingertips makes it turn red?

[@flannelguydiy6458]

it means you probably were using the table saw without a guard.. lol

Great video. I’m sure I’m correct on this, but for future videos on this product, consider clarifying what the colors indicate.

[@stevemiranda3659]

Why is the water proof one cheaper

[@buckwheat12n]

Can this pick up possible voltage that may have leaked into water i.e. swimming pool etc..?

[@flannelguydiy6458]

no

[@jasperjones6962]

I have bought two of these and they glow even with wires with no current going through the wires.

[@flannelguydiy6458]

make sure you check the settings

[@baranov649]

thank you for watching

[@FrankBenlin]

Was it?

[@philg4116]

@@FrankBenlin It works, but you get spurious results which are probably not its fault but rather due to dead wires affected by nearby fields from hot ones. So some effort is required to get clarity, which can be frustrating. BUT, I should add, false negatives are surely impossible.

[@FrankBenlin]

@@philg4116 Okay. Thank you for responding.

[@AlexanderKachowski]

I came to try understand meaning of different sounds and different flashes since there is no English description. But you don't have it too. Yes and it is 1 year ago. Everything is changing so fast.

Can a voltage tester detect a break in a wire?

[@flannelguydiy6458]

it cannot detect Where the break is

[@abcdefghijklmnopqrstuvwxyz0]

​@@flannelguydiy6458do you know how that tool is called to detect the break in a wire? if there's such a thing? thanks

Fun bonus, it will also detect if an ionizer found on many air purifiers is actually running.

These are banned in the UK in most industrial settings as they do not work on some cables such as SWA and the only approved method for testing for dead is prove the tester, test all power sources including earth and neutral. Then prove the tester again. This is standard in the UK but non contact testers and volt test screwdrivers are banned for safety reasons

[@Horizon301.]

Would this work for basic diy though in the UK? If you put it against the cable

[@3D-Dan]

On internal cables yes, on external armord cables no, sometimes they flag in dead cables with transient voltages such as RF but as they are not dependable and UK voltage is 230v they are not used, only volt testers such as fluke are used to verify the voltage with a lo-Z meter and in industry meters are always tested with a check box before and after testing ​

[@Horizon301.]

@@3D-Dan I assume a security light would be fine with it then, nothing special in terms of cable.

[@3D-Dan]

Yes it should work but safer with a volt tester such as a fluke T90
