Oh this thing is worth every penny. Just don’t forget that you have to turn it on to use it. Ask me how I know!

Three testers in one, thanks klein

Yeah I was pretty impressed for the quality and usefulness of it!

Very detailed!

Well, they’re $38 now….so, closing in on $40

yup, grounds and neutrals land on the same bars in the panel

Yup that's why when I troubleshoot I always use my Meter too or have with on me

Thank you very much I couldn’t figure out why my klein read 30 vac but everything I had plugged in was working fine. I started to think I might be trying to draw to much power with only 30 available. I was going to check and replace all outlets in that room BUT when I tried my FLUKE reader it read CORRECT.

They work fine, but not the same tool/tester. $.25? 25cents?

Do you know of any sensor that can detect a bootleg ground……they join at the main panel regardless. Only a time domain reflector could see that the ground joins the neutral at the outlet instead of the main panel.

Happy Halloween too you guys buddy

Good night too you guys please pray for my son is sick a can we do know y my son is sick please pray for as buddy

Some secrets are kept! 💪🏻

Apparently the box in the bedroom is not grounded. Adding a wire from the box to the receptacle won't help in that case. Are the other receptacles grounded? Do all the receptacles except for the one in the kitchen show correct polarity? If the answer to the first question is yes, then you can put a GFCI receptacle in there. If the answer to the second question is yes, then remove wires (power off) then check for hot wire (power on) using a multimeter with one probe on ground wire or metal box and the other on a wire. The one that reads approximately 120v AC is your hot wire. Alternatively, use a non contact voltage tester for this, which would be easier. You could also just swap the wires and retest, but testing first is more conclusive and leaves no doubt.

The GFCI outlet when tripped is removing the neutral and hot connections. I think the outlet tester is recognizing this after it has been tripped.

It creates a direct short to ground.

@@TheDurbinCompound Actually this tester does NOT create a direct short between the hot and ground when you press the TEST button. If it did, it would cause a non-GFCI circuit breaker to trip because of an over current condition created by the direct short (ex: >15A on a 15A branch circuit). When you press the TEST button the tester creates a much smaller leakage path (fault) between hot and ground which will draw a current of between 6mA and 9mA. GFCI outlets or breakers are designed to trip if they detect a hot to ground fault current of over 5mA and should therefore trip when confronted with this simulated fault. A standard breaker would happily supply this leakage current, in fact any leakage current up to the current rating on the breaker handle would be supplied. And if that leakage path was through your body core that is more than enough current to potentially kill you at 120v. But a

That's why he never took off the hot lol cheap one and meter way to go

This tester is really not design to test for a circuit breaker. There is a specific tester that I use that is fantastic and it is available from Klein Tools and others for about $22.00.

Yes. It will be able to trip the GFCI and tell you.

Yes it does. The RT250 is light-years better than the three light testers.

I would not recommend. It takes a lot to trip a regular breaker

That means “HOLD” it will keep the displayed on the screen for longer so when you unplug it, and in the case of needing to flip it over, you’ll still be able to see what it says. Does the same thing if you plug it in and unplug it. I moved the wires, it lost power, went into Hold Mode

No, you won’t be able to measure that

You wouldn’t use this on a two prong (non grounded) outlet. It requires a 3 prong outlet with a correctly wired hot, neutral, and ground.

Open neutral is sometimes caused by a wire nut that has come loose or a bad connection somewhere along the white wire. The wire is most likely not damaged in the drywalled area. I would open up other outlets in the room or the current outlet you are working on and check the connection of the white wire. If that is the only outlet that doesn’t work, then the problem is most likely right there

@@TheDurbinCompound ok thank you so my focus is the white wire. I will try to find where it’s jumped from. I did check one other box but all looked well I’ll continue my search. It’s odd cause the outlet is right beside the breaker box

@@bfoust3488 it is possible that the white wire fault you’re looking for is that the white wire for that circuit is not securely connected to the neutral bus INSIDE the circuit panel.

No. I don’t think so.

No plug checker will. That’s why electricians make false grounds so it passes the plug test on inspection

Nope

Means it does not need power from the outlet to work. Traditionally, these testers only work if there is power somewhere at the outlet

From other videos I've seen, it cannot.

Yes it does, it will display, "open ground"

Yes, but the test button on the device will not work without ground. The test button on the GFCI will work.

So does my killawatt meter have a load and that’s why this device seems to read about 1.5 volts higher?

This is a new product. Still readily available everywhere that I know of

HomeDepot is one of the only Klein tool dealer. I know my local electric supply house carries their full line as well

@@TheDurbinCompound oh nice!

I need used in Thailand

$20 USD

I haven’t tried it but in theory it will pop the breaker

waiting for the answer. Also test on a GFCI protected non grounded outlet. The hand held ones Do Not trip the GFCI, because they rely on the ground connection. comment please
