Customer Questions & Answers

White wire, black wire?

I had a track light that died. I removed it and I want to check the wires to see if the power is good. However, it's a black wire and a white wire and the voltage tester has a black lead and a red lead. Which is which? Black to black and red to white? Or black to white and red to black? I know that the black wire is power and the white wire is ground, but I have no idea which of the voltage tester leads is which (and the instructions aren't clear). Also, do I test it with the power turned on or off? It's a double switch and I don't know what position it was in when the light died, so I shut off the circuit breaker to be sure it's turned off. Thank you!
Asked by: Tekychick
You need to have circuit breaker power on to light the tester. Since you are checking AC voltage, red or black doesn't matter. Works either way. In the old days some used 110 DC voltage and you could check polarity of the voltage. Putting the red lead on the positive power wire and black on negative, would cause an indication by lighting one of two poles in the neon lamp. Depending on which pole lit up, would indicate polarity. Not used anymore because AC power lights up both at 60Hz. They just have not switched to same color wires because it looks more impressive. To see If your power is OK, hook up the tester (either color wires) to black & white power wires, turn on circuit breaker, turn your switches in all possible way's. If the tester doesn't light at all, your not getting power to the track fixture.

Does the black needle have to be touching the negative end of the wire or can i have it touch any...

Does the black needle have to be touching the negative end of the wire or can i have it touch any metal object while I probe with the red needle? What would happen if I touched the reversed(red on negative and black on hot wire)? Also how bright will the light be? Thanks!

110/220 VAC Voltage Tester is rated 4.0 out of 5 by 4.
Rated 5 out of 5 by from Cheap and easy If all you want to know is if the power is off and its safe to work I recommend this. Om not an electrician that's why this was so great for me, and it was only $3 it took me 25 mins to fix my outlet but I did it with pride. I'm happy I have this in my collection of tools.

Rated 5 out of 5 by from Can't go wrong Just what I needed. Works well and the price is great. Nothing fancy. Very basic. That's exactly what I needed. Comes with instructions too which is great because I had never used one before. Very satisfied.

Rated 5 out of 5 by from Perfect Size I needed one of these to help determine which wires were hot and neutral when hanging a light fixture. This worked perfectly and because of its small size, fits perfectly in my toolkit. It was also very cheap and seems sturdy.

Rated 1 out of 5 by from Very hard to see light when checking for 120/220 volts I bought this a couple of weeks ago and just tried it out today. It was daylight, but even shielding the sun I could not see the light light up when connecting to 120 or 220 volts.
