User questions & answers
| Question: | Can this trace a wire routing through the wall |
| Answer: | It's configured for 120 though you'd have to read the specs to see a out 240. |
| Question: | I have outlets wired in series: some NM. some metal-shielded. Can I detect signal in accessible wires "halfway" to the breaker to confirm route |
| Answer: | That would be a bit more difficult. You would have to replace the bulb with one of those socket adapters that have the socket and outlets to plug in cords. I think that would work to find the right breaker since you could plug in that part of the detector. |
| Question: | Will this product detect a bootleg ground |

User questions & answers
| Question: | Btw amazon photo shows 2 pack logo! even though you only get one set |
| Answer: | NO! It is, and the specs say, it is for 120vac. House wiring is 120vac. If you are wondering about 220vac, then you are probably thinking (giving you the latitude here, that you know about 220vac house service (which can be either 2 or 3 phase). Only one of those phases is used within the normal house receptacles. Even if you just look at the regular 3 prong plug between the two larger devices, you will see that is is the expected 120vac plug. A 220vac plug looks quite a lot different. Anyone trying to diagnose the (2 or 3) multi-phase service would typically just diagnose one phase at a time. So this *could* be used to troubleshoot 220vac - AS LONG AS you are just diagnosing *one phase at a time*. If you don't have clue as to what I have just spoken about then leave it alone! You are, in the least, going to waste your money, or burn out something, and at worst, possibly burn your house down. Get an electrician to help you out. |
| Question: | Does anyone else have issues with the sensitivity of this unit? I can't pinpoint a breaker, just a range of at least 5-6 push it to max |
| Answer: | Yes! Do this at your own risk, obviously. For some of the circuits in my house, the signal from the transmitter was too weak for the detector to pick it up through the breaker switch itself, but scanning the wires always worked. |
| Question: | Will this work on220 volt |
| Answer: | If you just need to test for continuity then you can put an rj45 jack on each end and tone one end and test the other you can see if you have continuity |
| Question: | If you take the breaker plate off can you get a better indication on a specific wire going into a breaker |
| Answer: | you will still have to connect the generator to the cable somewhere. since they are low voltage it should work. |

| Question: | Will this product be able to identify more than which outlets are related to a particular circuit; such as light switches, oven vent fans, etc |
| Answer: | That 69411 catalog number is for the: "Circuit Breaker Finder Accessory Kit". That was available when I purchased mine but I don't know about now with this virus problem. I do not believe that amazon will answer your question in this manor. Probably the only way to find out from Amazon is to just try ordering it and see what your response will be. |
| Question: | I have 220vac outlets, if the remote plug-in unit only works with 110vac can I go one side to ground and simulate a 110 circuit to find each breaker |
| Answer: | I am not sure but I would suspect code for high voltage lines should be properly marked for identification. |
| Question: | Does the power have to be on for the tester to work |
| Answer: | I don't know but im sure that the circuit wiring configuration along with the load center configuration will effect it's operating range. There are several variables that can effect the tester's operation. |
| Question: | Does it work for higher voltage like 220 v |
| Answer: | Does not have a sensitivity wheel, I’ve had no issues with it usually within one breaker its spot on. Just have to hit reset if u skip over the correct one to clear memory before re scanning |

User questions & answers
| Question: | Will this tester test the breaker itself, or will I need a continuity tester to test the breaker |
| Answer: | Your question is unclear, but I think you want to use it backwards. The unit has a transmitter, which you connect at an outlet (via duplex plug, clipleads, or standard light-bulb-socket adapter). Then at the service panel, you run the receiver down the circuit breakers, and it tells you (most of the time) which CB feeds that outlet. It does not allow you to select a CB and then use the device somehow to find all outlets that CB feeds. (I would love that feature as well.) |
| Question: | Extravie la pieza que se enchufa, hay manera de reemplazarlo |
| Answer: | Yes there is a red light that comes on when the plug is plugged into a live outlet. |
| Question: | Does the electrical circuit have to be powered up. I am trying to trace unused circuits |
| Answer: | No the transmitter needs the power from the outlet to send the signal down the line. The transmitter is the device you plug into the outlet. |
| Question: | Thank you for answering; I also need to know what the red button on the transmitter is for |
| Answer: | The small transmitter plugs into a target outlet and injects current pulses into the line, which can be detected by the receiver probe when held close to the path that the power goes through, which includes the breaker. The receiver antenna is most sensitive when oriented with the face perpendicular to the path, so that's why it should be held with the face sideways, with the up arrows pointing up. Whenever the bottom is pressed, it resets the sensitivity to the highest level, and each time it detects a strong signal, it reduces the sensitivity so it will ignore any lower level signals it encounters from that point on. That's the reason for the multiple passes, to keep looking for the strongest level signal and progressively reducing its sensitivity until it will only sound off on the strongest one, which is generally the target. You can go back and forth, just try to hold the unit at the same point going down the line of breakers to get an equal reading on all the breakers. Basically you just want to reduce the unit's sensitivity by having it pass by any strong signals. If you accidentally push the button while handling it, you just need to run through them again. If you find the target, you could flip that breaker and run through another pass, too confirm it no longer sounds off, which it shouldn't, if it's no longer getting power. Sometimes you may get two breakers that consistently sound off due to the wiring paths being close to each other and coupling the signal over. Shutting off one would tell you which one it actually is. Get a small rubber band and wrap it at the inner lip of the button to avoid inadvertent presses. I did that on the Circuit Detective one from HF, and it now requires a firm press instead of just a light touch. |

User questions & answers
| Question: | The volt sensor is so sensitive it goes off near an outlet. Is that normal? I thought I could stick it in the slots to find out which side was hot |
| Answer: | Yes, you can insert the tip of this tool into the slots of an outlet then press the button and it will tell you which side is hot. You can also use it to test the wires in a circuit if you are unsure which is the hot lead. If the wires are connected to the switch, outlet etc touch the tip to the bared wire at the contact point and it will tell you if it is hot. You can also just touch the insulation covering the wires to get a reading too. Try to keep the wires you are testing separted by a few inches if possible, this will help prevent any false reading you might get by voltage seepage from the insulated hot lead. If you didn't know - the hot wire in a circuit is usually black, red or maybe some other dark color, the white is the neutral or return and the green is the ground. Start by testing the dark wire first but as a precaution be sure the check the white also - someone may have wired in incorrectly and that could be a hot lead. I've had - well had, until I left it someplace - one of these for years and it's a good useful tool. So I gotta get another one now, and I'm getting one of these. |
| Question: | Can this be used as a circuit breaker finder |
| Answer: | You could use them to find a circuit breaker, if you had someone to watch the tester, while you went through your panel turning off and on your breakers untill you found the one that controlled that circuit. If you didn't want to do that then you will need to buy an circuit breaker finder kit. |
| Question: | does this tester work on low-voltage landscape lighting wires |
| Answer: | The non contact voltage tester will. |
| Question: | can it tell the diffrence between 220v and 110v |
| Answer: | If you can’t tell the difference 110v and 220v .You Dont Need A Meter. |
