Will this tester read 16 volts (Doorbell)? In the description it says "Detects voltage in range of 12 - 1000 VAC" but on the actual pen it reads "50V".
Asked by: DIYer4Life
I would go with what's written on the pen. Never used a tic tracer on a doorbell before? I guess 16v could hurt... Have used a meter to trouble shoot a doorbell.

I have a wall light switch that has stopped providing power to a ceiling fan/light fixture, regardless of whether the switch is on or off. Should this tester detect whether the power to this switch is hot?

I recently had some old knob and tube wiring replaced. I haven't finished patching the walls yet and there is one location with new wires where, when I get this pen about 6-8 inches away, it lights up red like crazy. I'm worried this is indicating something is wrong with the wiring. Any thoughts?
Asked by: CDawg
There is a hot wire under there somewhere.

Non-Contact Voltage Tester is rated 4.5 out of 5 by 592.

We live in an older house and a lot of the wires are not labeled or mislabeled or just plain weird... With this tester it is super easy to touch a wire or an outlet and know if you have power and which line is hot. It also helps to make sure you have turned off the right breaker when doing work or repairs. It even turns itself off after it hasn't been in use for a few minutes.

Absolutely flawless, hands down one of the best purchases I've made in a long time.  I can't speak highly enough about this product, which is solidly built and perfectly designed.  It has become a staple of my homeowners tool kit.  I've used it at my house, several friends houses, and my wife's business during electrical renovations across a wide variety of DIY projects.  This unit has helped me run wiring, map circuits, rewire rooms, install sockets and plugs and switches.  It's a constant companion and I love it.  It works peerlessly sounding both an audible and visual alarm when current is detected.  It's so easy to decipher, my wife has used it to help me map the wiring in my new house since the diagram on the panel was completely inaccurate.

Battery comes with the product does not come out or go in with gravity force. I removed (with lot of difficulties) original brand new battery and replace with other brand, and it flows smoothly with gravity force, so I won't return it, just be cautious when replacing battery. Make sure it goes in by gravity force only so it can come out by gravity force only. Other than that it looks good and works excellent.

This appears to be a well-constructed tool that comes with batteries included. It has both VISUAL and AUDIBLE indicators of a "hot" wire. It will indicate if a power cord plugged into an outlet is "live" but only on the "hot-wire" side of the cord. The end of the tester, however, will not fit into the "hot" side of an outlet, so if you want to check an outlet without removing the face plate in order to access the wires/terminals, you need to plug in an extension cord and check that. Nevertheless, if you are opening a box to do some house rewiring and you want to make sure that you've turned off the correct breaker, this tool is very handy for that purpose. So, in my opinion, it is a tool that does one thing well -- but only that one thing. If it saves you from a bad electric shock (or worse), however, then it is well worth its modest price.

Rated 5 out of 5 by from Accurate and Durable Bought this based on my cousin’s recommendation and am very happy. He is a journeyman electrician for reference. Need to be touching a wire to detect hot where as other brands/cheaper ones light up red when you’re just close, which isn’t helpful if you have a bunch of wires together. I have also dropped it a couple times from about 4 feet and it still works great

Very easy to use, push the button and insert in the plug or hold over wires. Turns red when power found and beeps. Can be turned off by pushing the button again or if you forget, it will turn off by itself. Came with a battery installed. Great for verifying you've tripped the right circuit breaker when changing outlets etc. I would by it again!

However it does not work at all on newer outlets with the tamper resistant feature (which have been required in all new construction and remodels since 2008 per the NEC) since the tip cannot be inserted.
