It's caused by load current that flows through the impedance of the neutral wire. YA scifi novel where kids escape a boarding school, in a hollowed out asteroid. If a circuit is run as two wires from the panel to the load, then when the breaker trips everything in the circuit will be de-energized. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. First of all I would test using the multimeter at both ends. I think it just boils down to my fundamental understanding (or lack thereof) of how bulbs work. 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. Are the neutral and ground (green) wires reversed or shorted? There's probably 10 feet of wire between the outlet that's good and the one that's bad. It is not uncommon to find phantom voltage on non-energized conductors on 3-ways. (Referring to the OPs). All the other outlets work fine. If not it may be on a run with other outlets and the fault in the run could be upstream in another outlet. Make sure to check the equipment voltage on the machine because in many cases the machine wiring configuration may be adjusted for different voltages, however this will depend on the specific machine that you have. Learn more about Stack Overflow the company, and our products. To make sure this is the case before ripping the wire out and replacing it, you should A) Confirm there isn't any sub panel or fuse in the wire path B) Disconnect all wires from any hardware (plugs, breakers) and make a no-power circuit to test impedance. Electrical Safety Advice | ElectriciansForums.net. it may be that you have a faulty switch or an induced voltage that shows you have 50v on the switched live conductor.

Circuit breaker is 15a and also connects to 3 light switches controlling 6 light fixtures total. Voltage should read about 120 V (typically 115 V to 125 V). This is exactly what happened to me. With a standard switch I am getting 120v on, 0v off as expected. Also, what does the outlet show when you test in AC? Most likely the next one in sequence would be the one physically closest, but you'll again have to revert back to my answer of testing each outlet down the line. Hi John, This list of articles will help you learn about the features and benefits provided by GFI and GFCI Receptacles and how they are wired. I plan on trying to reset all of my breakers again to make sure I did it properly and with enough force. Considering it's getting 13v even on going hot to ground, maybe that means the hot wire melted somewhere (?). Flush mount power outlet, straight blade, grounding, Al and Cu, side wired, steel strap. 30V should, then, be very unlikely in a direct circuit even with poor connections. This is an older home which was upgraded with a significant expansion and electrical circuits that were joined together in a manner driven by the convenience of a circuit being nearby as opposed to other factors that might appear more logical, such as putting all kitchen outlets together. I did verify when all these 3 wires are disconnected that: black is hot when switch is on, white and ground has no electricity. Thanks for your electrical wiring question Paul. Privacy Policy. Clamp a wire stripper around the outlet end of the 10/4 cable so it's 1 foot (30 cm) from the end. If so, what is it and how much current would it cause to leak from the line to the load. Tug on both ends to ensure that it's held together tightly. So more than likely, what you are seeing is normal when testing with a meter that most use. Google phantom voltage on 3-way . Hey guys. This handy tool has multiple uses: typically this involves turning the circuit OFF and inspecting each outlet for a burnt wiring splice or a faulty connection. How do two equations multiply left by left equals right by right? New information (both scenarios have the switch off): So, not sure why I only get a reading with the circuit off when the leads are backward. The electrical circuit load of these high consuming devices is placed on and through every splice or connection within the circuit. Very handy and easy to use. How can I detect when a signal becomes noisy? Why would the receptacles in the kitchen not have power after replacing one of them? Thanks again guys, its semi-embarrassing to not understand this stuff. By the way, the wiring in my house is all aluminum. The best way to troubleshoot this type of electrical problem is to locate the upstream outlet that is working and giving normal voltage readings. Only appliances on this circuit are the fridge, microwave, and toaster oven. Thanks for all of the thoughts so far. See how wiring electrical outlets for the home are done. If you continue to have issues, check the gauge of the wire to ensure it is the correct size for the voltage. At the switch, I am measuring 0v when off (load to ground, load to neutral, neutral to ground - all 0v). While not wrong, this doesn't add anything that wasn't already stated. so I got these readings and they are different from a normal working AC outlet so there's something obviously weird going on with this circuit. Outlet 1 which has only the microwave on it gave me weird readings. Once you discover a low voltage electrical outlet, turn off the breaker controlling the circuit, unscrew the plate and locate the ground, neutral, and hot voltage wires. A single reversed neutral and ground can compromise the entire ground system. Making statements based on opinion; back them up with references or personal experience. About 6 months ago, I replaced the receptacle in this outlet with new one (I actually did for all outlets inside the house, except garage), and did verify that it works properly with a receptacle tester. A wire stripping tool used to safely strip electrical wires. GFCI Wiring When replacing the light fixture I noticed that there is only 30 V AC between the white and black wires. Hi Cory, 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. Shop Utilitech. Does the voltage change when you turn the switch on? This is a measurement of voltage drop (also called IR drop). What do I look for? Next, tape, twist, and wrap one end of the old wire with an end of your new wire. Why am I only getting 92V at receptacles? In the process of attempting to resolve a similar problem this evening, my son and I discovered a similar problem and our solution was not related to any of these suggestions so I though I would share the resolution we found.
