By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Given that, are you saying that it's possible there's another breaker that might need to be reset? I suspect you may have something called a multi-wire branch circuit, which uses one set of three wires (rather than two pairs of wires) to handle as much load as two separate circuits. There's no need to split breakers on a 30 amp panel because there is only L1 and 120 volts present. I checked the voltage to the ceiling outlet Its only getting 30 volts. The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets. I checked it out with my multimeter, and I tried it in a different closet. https://my.fluke.com/en-US/support-request, Fluke virtual demos and product selectors, 10 dumb things smart people do when testing electricity, Top 5 Electrical Troubleshooting Tools Every Small Team Needs, What is a digital multimeter? If it's in a kitchen, look for a tripped GFCI outlet somewhere nearby. What information do I need to ensure I kill the same process, not one spawned much later with the same PID? When I test with one probe in the outlet and one on the ground it reads 122- 124 volts. There is a process of elimination here that needs to be followed and wild conjecture isn't going to help anything. This is one of many outlets on the circuit. Asking for help, clarification, or responding to other answers. I bought this house a little over a year ago so I'm not terribly familiar with how the kitchen is wired. Keep the wires separated and safe and then flip the breaker back on. If this is the issue, you would have to check out each receptacle along the line until it returns to 120V from hot to neutral, this would mean the problem is between that receptacle and the last measured. On the switch side I am using a multi-meter and on the plug side I am using a plug in meter, which I have read tends to run on the very sensitive side. So on the same conductor that is maybe 30 feet apart, there is a 30 V delta measuring at both ends. Any ideas welcome. Learn how to identify low voltage at an electrical outlet and how to fix it. At the switch, I am measuring 0v when off (load to ground, load to neutral, neutral to ground - all 0v). TV Arcs with Cablebox through both Coax and HDMI, Both prongs of an outlet carries live electricity of a switched plug, Confusion while diagnosing an open ground, Double-pole breaker connected to two receptacles/outlets on same column/post, Is it safe to use the neutral wire as a ground. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. When you look at intermediate sockets in the circuit, commonly a pair of wires carries power to the socket and another pair carries the power to the next socket in the chain. leakage current is still there as wasted electricity. I just replaced a broken light fixture in my closet. Thanks for your input. Sure enough once I pulled the switch out and the neutral bundle a wire came out of the wire nut. As mentioned previously, you only need 2 wires for 240V. The outlet is in a corner location and has not been used since we moved in 8 years ago. All the other outlets work fine. The outlets arent split so there should not be a long run with a powered wire side by side. Another thing that might be related: A couple of times over the years if we stop the garage door halfway up (so the dogs can get in or out) the garage door opener would lose power completely and I would have to unplug it and replug it in. You can think of the ground connection as a wire running back to the source (the main panel or the transformer), where it's connected to the neutral. Why am I only getting 92V at receptacles? Visit the kasa smart store. NEMA L15-30AR Flush Mount Locking 30-Amp Recessed Industrial Round Outlet, Black. Making statements based on opinion; back them up with references or personal experience. Thanks for any help you can give. off) circuit, you can sometimes read a "phantom voltage" caused by coupling with other nearby live wires. Problem with Outlet Receptacle If neutral-ground voltage is about 120 V and hot-ground is a few volts or less, then hot and neutral have been reversed. To learn more, see our tips on writing great answers. This site saved me from having to pay someone which is admitting defeat which means I can go to my wife and look up into the sky and simply say: Genius. Each hot should go to a pole on the breaker panel - this should by code be a 2 pole breaker. There is a problem with a duplex outlet in the living room. Thank you both for the pointers. Hot-ground reading should be the highest of the three readings. Strangely, this is giving me 120V!! Is the outlet wired correctly? Voltage should read about 120 V (typically 115 V to 125 V). you have a loose/poor neutral connection somewhere in the circuit. Are the receptacles split? Welcome to ElectriciansForums.net - The American Electrical Advice Forum. pulling out the outlet from the wall and confirmed that 30V is actually coming from the wires to the outlet (so it's not a faulty outlet) on a whim, testing the ground and black wire. Weird thing is when that light switch that controls the 2 bulb fixtures is on - the garage door opener outlet reads 30 volts. and our If you say the fixture doesn't work even though the old one did, perhaps a connection came loose somewhere and now you have an open circuit with only the phantom voltage. However (of course) it's buried in sheetrock. In fact, hot-ground is equal to the sum of the hot-neutral and neutral-ground voltages. Electrical plugs designated as 20-amp will not fit into 15-amp outlets. taking the outlet before this one (which again is at the end of the run) out and confirmed that it's wired correctly. I don't see how the old fixture could've worked if it was actually only getting 30 volts, so something must've changed during your installation. This method should be applied to all of the connections to the circuit outlets. At the switch, I am measuring 0v when off. The first thing I would do is take your multimeter and go to another fixture and make sure you see 120VAC on it - just to make sure the meter works correctly (assuming you are in a 120VAC country). Are the receptacles split? By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy.

Youll get 120 VAC both ways. For example: if you have a dimmer elsewhere on your circuit, it could be confusing the heck out of your meter. Does Chain Lightning deal damage to its original target first? So I hooked up as with any other new light fixtures I installed (or replaced). The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation. It is #1 on my list of bad but allowed wiring practices. It appears that the outlet circuit may have lost connection with the neutral, so the circuit wiring and connections will need to be examined to identify the problem. Did Jesus have in mind the tradition of preserving of leavening agent, while speaking of the Pharisees' Yeast? This light isn't on a three way switch. Asking for help, clarification, or responding to other answers. I really hope it's not a melted wire because I have no clue how one would fix that if it's in the middle of the wall. They both read 120 volts. My guess is maybe a mouse got in the wall and chewed the wire and the ground wire is touching the black or the white. If with the circuit breaker on, the same amount of items are are lacking power as were unpowered when the circuit breaker was off, you have an open connection in the wiring leading to the first socket in the daisy chain, or the incoming connection to the first socket is bad. To the OP, one other point: Don't just look at the receptacles that are faulty. Why would an 'off' traveler have voltage on it? If no backstabs, check all connections. You can reverse the probes and for real voltage, get the same reading. I can't seem to find any other outlets reporting low voltage so I'm guessing there's nothing wrong with the breaker or the wires. If you haven't flipped all connected pairs of breakers off and back on, it may be that one of the breakers has an insufficiently-strong "tripped" spring to switch off the other breaker, so the untripped breaker holds the tripped on in what, Luckily for me this turned out to be the problem. I will draw diagrams to attach to this topic. If neutral-ground voltage is 0 V - again assuming that there is load on the circuit - then check for a neutral-ground connection in the receptacle, whether accidental or intentional. With a standard switch I am getting 120v on, 0v off as expected. Flush mount power outlet, straight blade, grounding, Al and Cu, side wired, steel strap. Simply attach your 15-amp rated devices plugs into the transparent female end of the adapter and plug the 30-amp locking male end into the generator. The features and benefits of GFCI outlets and receptacles will give you a clear understanding of the importance why these safety devices are required by code to help protect you and your family against accidental electrical shock hazards. If you need to plug in at a location where there is no 30 amp RV style outlet you can buy an adaptor at any RV dealer that will adapt your 30 amp RV plug to a standard 15 or 20 amp duplex receptacle. After changing out all the receptacles with tamper resistant ones I was getting 120v from line to ground, 20v neutral to ground and 95v neutral to hot. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Either multiple breakers were tripped (but not showing it) or I didn't proper flip the breakers when I tried it the first time. Do you have 2 kitchen circuits with 2 GFCI receptacles? So, why do they leak so much current??? Garage door opener stopped working one day. You are using an out of date browser. This is a potential safety hazard and the condition should be corrected immediately. The best way to troubleshoot this type of electrical problem is to locate the upstream outlet that is working and giving normal voltage readings. I replaced all the sockets in a house because they'd used cheap sockets and daisy chained them through the pushin connections. For all intents and purposes, AC does not have polarity, so it doesnt matter which probe is on which terminal. So more than likely, what you are seeing is normal when testing with a meter that most use. Hot-neutral is the load voltage. Light fixture, power source and range vent fan & light wired together? The AVR is a circuit that regulates and balances the amount of voltage being output from the generator. Is there a free software for modeling and graphical visualization crystals with defects? Wiring Electrical Wall Outlets Try checking potential from the neutral to ground and see what you get. If the electrical utility company reports that the electrical service power is OK and the condition persists then it is best to contact a licensed electrician who can perform electrical troubleshooting tests at the electrical panel to identify the electrical system problem and make the necessary electrical repairs. So I tried: pulling out the outlet from the wall and confirmed that 30V is actually coming from the wires to the outlet (so it's not a faulty outlet). Likewise if a multi-wire branch circuit is run as three wires and both breakers are tripped or switched off, everything will be de-energized. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Hopefully you will find the bad connection right at the panel but if it is more involved, I strongly recommend doing that rather than looking for voltage with the circuit live. A three-slot receptacle has a hot-slot (short), a neutral slot (long) and a grounding slot (U-shaped). Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. if the outlet was wired using the stabs (wires pushed in) not screwed in the connection of the hot side probably melted or you would have 120 from hot to the ground.

Dave, Heres a hint about low power at recepticle or doing any DIY electrical work: Write down on paper everything you move, remove, or adjust at the breaker box. A 15-amp circuit is usually served by 14-gauge wire and is protected by a 15-amp circuit breaker or fuse. If the reading of 203 volts is correct then the electrical system at your location may be 120/208volts, 3 phase. In what context did Garak (ST:DS9) speak of a lie between two truths? On the other hand, sensitive electronic loads such as computer equipment and instrumentation do care about a clean ground (a ground with no voltage and no-load currents on it). I know US and UK practice are different here, in the UK we have a rule that a circuit must not be switched on until the resistance of its ground is measured and recorded as satisfactory. If not it may be on a run with other outlets and the fault in the run could be upstream in another outlet. K KeepItSimpleStupid Joined Mar 4, 2014 5,088 Oct 3, 2017 #3 They should be banned IMO. That is to say that the problem can be with the wires exiting a working receptacle on it's way to the place that doesn't work. All items (lights & sockets) on that circuit should die. Put someone on the same pedestal as another, 12 gauge wire for AC cooling unit that has as 30amp startup but runs on less than 10amp pull. How to check if an SSM2220 IC is authentic and not fake? The on/off switches are auto sensing so the load may not be making the sensing correct. PyQGIS: run two native processing tools in a for loop. Learn more about Stack Overflow the company, and our products. There is obviously some potential there or the LEDs wouldnt light. But, not with a switch that has a relay, or an open contact with an air gap, switching the load. Voltage between hot and ground is 120 volts. Worse, a variety of factors may cause the amount of available voltage and current on the "disconnected" circuit to change unexpectedly, so even if a voltage tester shows that a circuit is "dead" that doesn't mean it won't seemingly-spontaneously become lethally energized as soon as the tester is put away. 4.5 (735) 100+ bought in past week. If not at that outlet go to the next one prior to that and do the same check. Be sure to make a good splice and use the correct size wire connectors approved for the number of wires, and the gauge of the wires. Does that make sense? Review invitation of an article that overly cites me and the journal. This is a measurement of voltage drop (also called IR drop). It would be essential to have the electrical utility provider verify that the voltage on there side is within tolerance. Before I go ripping out sheetrock, is there something simple I can do to further diagnose things? Why don't objects get brighter when I reflect their light back at them? The wiring in the switch is correct as far as the switch leg is concerned, again the white being the hot should preferably be marked. Ive seen as much as 85 volts on some.
